Fault CodesCause & Solution
F001
Failure of
electronics
power supply
Cause: Failure of the electronics supply voltage (terminals 5U1, 5W1, 5N1) in “RUN” state for longer than the “restart” time set in parameter P086 or the electronics are operating on undervoltage.

Possible fault causes:
– Line contactor has opened in “RUN” state
– Brief supply failure
– Supply voltage too low

Soultion:

Fault value: r047 Index 002 to 016:
1 Electronics supply voltage in “RUN” has been interrupted for longer than setting in P086 i002 Duration of actual supply failure in 1/10 seconds
2 Supply failure prewarning responds periodically –
3 Supply failure prewarning is active for longer than 1.28 s
F004
Phase failure
in armature
supply
Cause: The supply voltage RMS value, calculated from the area of each supply half-wave (rectified average value * peak factor), must be greater than the response value for phase failure monitoring

The distance between two identical supply zero passages of a phase must not exceed 450 degrees. If one of these two conditions remains unfulfilled for longer than the “restart time” set in P086, a fault message is activated. After switch-on, the converter waits in operating states o4 and o5 together for a period not exceeding the setting in P089 for voltage to appear at the power terminals (and for field current) before activating the fault message.

Possible fault causes:
– Parameter P353 is incorrectly set
– Armature phase has failed
– Line contactor opened in operation
– Fuse has blown on three-phase side in armature circuit
– Fuse has blown in power section
– Interruption in a thyristor firing pulse cable (auxiliary cathodes at connectors X12, X14, X16 are voltage carriers).

Soultion:

Fault value:
1 Voltage failure has occurred in armature supply (1U1, 1V1, 1W1) (when P086=0)
2 Delay time set in parameter P089 has expired in operating state o4
3 Fuse has blown in power section
4 Voltage failure has lasted longer than period set in P086 (if this is >0)
6 The “Main contactor checkback” (control word 2 bit 31) [see also P691] did not switch to “1” before the time set in P095 ran out, or switched back to “0” during operation [V1.8 and later].
F005
Fault in the
field circuit
Cause: The line voltage RMS value calculated from the area of each network half-wave (rectification average value * peak factor) must be greater than the response value for phase failure monitoring

The distance between two identical network zero passages of the voltage for the field converter must not exceed 450 degrees. The actual field current K0265 equals < 50% of the required field current setpoint K0268 for more than 500ms. This monitoring function is effective only if the field current setpoint corresponds to >2% of the converter rated field current. [In SW 1.9 and later, the percentage (50%) and time (500ms) can be altered in P396 and P397 respectively] If one of the fault conditions described persists in operation (or ≤ o4) for longer than the “restart” time set in P086, the fault message is output.
After the converter is switched on, it waits in operating state o5 for a period not exceeding the setting in P089 for the field supply voltage or sufficiently high field current before this fault message is activated. Monitoring for timeout as the field decays or builds up after initiation of field reversal (fault values 6 and 7) is not implemented until SW 1.7 and later.

Possible fault causes
– Threshold for phase failure (P353) set incorrectly
– Undervoltage / overvoltage threshold (P351, P352) set incorrectly
– Field phase failed
– Line contactor opened during operation
– Fuse blown in the field circuit
– Field current controller and/or field current precontrol not optimized or badly optimized (check P112, P253 to P256; possibly execute current controller optimization)
– Check P396 (field current monitoring threshold) and P397 (field current monitoring time)
– If the fault value is 6: Offset fault in the actual field current value sensing, relevant parameter: P825.i01-i03 (Offset depends on P076.i02) or P394, P395 (Threshold and hysteresis for message I_field < I_field_min) must be checked
– If the fault value is 7: Circuit for the “new” field direction is interrupted (e.g. because the contactor for “new” field direction does not pick up), P398, P399 (Threshold and hysteresis for message I_field < I_field_x) must be checked

Solution:

Fault value:
1 Voltage failure occurred in the field supply (terminals 3U1 and 3W1) (if P086 = 0)
2 Delay time according to P089 elapsed in state o5.1. Wait until the voltage and frequency at the field power section are within the tolerance range (P351, P352, P353, P363, P364).
3 Delay time according to P089 elapsed in state o5.0 Wait until IField act (K0265) > 50% of the instantaneous field current setpoint K0268 [as of SW 1.9, can be altered by means of P396] and until “I Field extern > I f min” (see P265)
4 After P086 > 0 has elapsed (time for automatic restart) in operating state ≤ o4: Voltage failure in the field supply or
IField act (K0265) < 50% IField set (K0268) for longer than 500 ms [as of SW 1.9, can be altered by means of P396 or P397] or "I Field extern > I f min” (see P265)
5 When P086 = 0 (no automatic restart) in operating state ≤ o4: IField act (K0265) < 50% IField set (K0268) for longer than 500 ms [as of SW 1.9, can be altered by means of P396 or P397]
or “I Field extern > I f min” (see P265)
6 If field reduction before field reversal, I_field ≤ I_field_min (P394) is not reached within 30 s
7 If field build-up after field reversal, I_field > I_field_x (P398) is not reached within 30 s
F006

– Rectifier stability limit αG (P150) is incorrectly set
– Drive is operating at αG limit (e.g. due to supply undervoltage)

– EMF is too high because field weakening is not selected (refer to P082)
– EMF is too high because field current is set too high (refer to P102)

F041
Ambiguous
selection of
parameter set
or ramp-function
generator
While an optimization run is in progress, the function data set selection must not be changed. Fault F041 is displayed if another, different function data set is selected while an optimization run is being executed.
– Check whether ramp-function generator parameter set 1 or 2 or 3 (parameters P303 to P314) is clearly selected. If parameter sets 2 and 3 are selected simultaneously for more than 0.5s, then fault message F041 is displayed. While the parameter set selection is ambiguous, the system continues to apply the last clearly identified ramp-function generator parameters.

Possible fault causes
– P676 or P677 (selection of binectors which determine the active function data set in control word 2, bits 16 and 17) is incorrectly set
– P637 or P638 (selection of binectors which determine ramp-function generator setting) is incorrectly set

Fault value:

F042
Tachometer
fault
Possible fault causes
– Open circuit in tachometer or pulse encoder cable.

– Pulse encoder supply has failed.
– Polarity for actual speed value (P743) is incorrectly set.
– Armature circuit data (P110 und P111) are incorrectly set (execute current controller optimization run).
– Tachometer or pulse encoder defective
– Pulse encoder supply voltage is incorrectly set (P140)
– The field polarity is not reversed by the external hardware when the field is reversed.

– 2 Polarity of tachometer or pulse encoder is incorrect: i003 Actual EMF value (K0287) in case of fault
F043
EMF too high
for braking
operation
This fault message is activated if the following 5 conditions are fulfilled when a torque direction reversal is requested (selection of MI or MII):
– P272=0 (fault message is parameterized and not alarm + field weakening)
– A parameterized, additional, torque-free interval (P160 ≠ 0) has expired
– Parallel drive is ready for engagement of the new torque direction
– The absolute value of the armature current (K0118, filtered with P190) requested in the new torque direction is >1% of P072.002
– The calculated firing angle (K0101) for the armature current requested for the new torque direction is >165 degrees or >P151 when P192=1

Possible fault causes:
– No “speed-dependent field weakening” (P081=0) is parameterized even though operation in the field weakening range is needed for the requested maximum speed
Note: In motor operation, it is possible to reach EMF values corresponding to the peak of the phase-to-phase supply voltage at a firing angle of αG=30° (rectifier stability limit P150) and low armature currents.
– Setpoint EMF for field weakening operation too high (parameter P101 is set too high)
– Supply voltage dip
– EMF controller or field current controller is not optimized, possibly resulting in excessive EMF on power-up.

Fault value: r047 Index 002 to 016:
1. Calculated firing angle (armature) before limitation (K0101)
– i002 Instantaneously measured actual EMF (K0287)
– i003 Armature current controller setpoint (K0118)

Possible fault causes
– Open circuit in supply cable
– P710 is incorrectly set
F048
Fault in
measuring channel
for digital
speed sensing
using pulse
encoder
1. Disturbances on encoder cables: Faults on the encoder cables (transitions to 0 with a 1 signal or to 1 with a 0 signal) are signalled as a rotational direction change by the evaluation circuit. Frequent changes in rotational direction can occur only at speeds around 0. The fault message is activated if 10 consecutive pulse encoder signal evaluations identify “direction of rotation change” at a speed of ≥ 48 rev/min and an EMF > threshold (see below).
2. Pulse encoder defective: The fault message is activated if, at an EMF > threshold (see below) 10 consecutive pulse encoder signal evaluations identify “implausible characteristics” of these signals (i.e. frequent rotational direction changes, edges too close together, failure of an encoder cable or short circuit between two encoder cables).

Possible fault causes
– EMC-related interference on a pulse encoder signal (terminals 28 to 31)
– Interruption in an encoder cable
– Short circuit between an encoder cable and the supply voltage or another encoder cable
– P110 or P111 is incorrectly set (resulting in incorrectly calculation of EMF)


Note: When the speed encoder is operating correctly, signal sequences, which are characteristic of a faulty pulse encoder or disturbances on the pulse encoder cables, may occur continuously at the input terminals (e.g. continuous changes in rotational direction or short pulse intervals) at about 0 speed, e.g. as the result of slight oscillation around a bright/dark transition on the speed encoder disk).
Fault value:
1 Disturbances on encoder cables
2 Defective pulse encoder
F050
Optimization

possible
Cause: A fault has occurred during an optimization run.

NOTE: The contents of r047, Index 002 to 016, can provide specialists with more detailed information about fault causes. For this reason, please read out and document all the indices associated with this fault.

Fault value:
1 Armature current is too low when α=30° and EMF=0. (average armature current <75% of IA, motor or <75% of IA, rated)
Possible cause:
– Armature circuit interrupted
– High-resistance load
– P150 (Alpha G limit) has been set to excessively high value

2 It was not possible to determine the armature circuit resistance (P110) because the armature current was ≥ 37.5 % of P100 in fewer than 20 of the 150 firing cycles of the measuring phase.
Possible cause:
-Armature current of 37.5% of P100 (I A, motor) is no longer possible (although a current of 75% of P100 was already
flowing, maybe a fuse has blown).

3 Armature current peaks are too small at α=30° and EMF=0 (armature current peak value <50% of IA, motor or <50% of IA,rated)
Possible cause:
• Armature circuit inductance is too high (field supply from armature terminals)
• P150 (Alpha G limit) has been set to excessively high value
Possible remedy:
• Reduce P100 (IA,motor) while this optimization run is in progress

4 The armature circuit inductance (P111) cannot be determined from the sampled values of the armature current and line
voltage of the armature current crest last generated
Possible cause:
•P100 (IA,motor) or r072.i002 (IA,rated) very much smaller than actual motor rated current of the armature
•LA >327.67mH (armature circuit inductance too large)
•P100 (IA,motor) very much smaller than r072.i002 (IA,rated)
•Armature circuit short-circuited

5 Offset adjustment of actual field current sensing is not possible
(value detected for P825 is outside permissible value range)
Possible cause:
• Fault in actual field current sensing circuit
(defective A7004 gating board or A7001 electronics board)

7 The field circuit resistance (P112) is indeterminable
(the actual field current does not reach the internally specified setpoint of 95% of P102 as a result of P112 variation)
Possible cause:
• RA >3276.7Ω
• Fault in actual field current sensing circuit (defective gating board or A7001 electronics board)
• The command “Inject standstill field” is applied
• P102 is set too high
• A thyristor in the field bridge is not firing

8 80% of rated EMF (K287=P101 – P100 * P110) cannot be reached within 15s (or maximum of the three set acceleration
times)
Possible cause:
• Acceleration time (P303, P307, P311) is set too low
• P101 does not match the set maximum speed (UA at nmax < P101) or setting for P102 is too low
• The command “Ramp-function generator enable”=0 or ”Ramp-function generator stop”=1

9 Field current control loop is not stable enough to record field characteristics
(30s after injection of internal field current setpoint, actual field current is deviating by more than (0.39% of P102 + 0.15 %
of r073.002) from the setpoint)
Possible cause:
• Field current controller or field current precontrol is not optimized or optimized badly (check P112, P253 to P256 or
execute a current controller optimization run (P051=25))

10 Field characteristic is not uniform
(i.e. in spite of field current setpoint reduction, the flux values of this measuring point calculated from EMF and actual speed
are rising)
Possible cause:
• High armature reaction and sharp load variations during recording of field characteristics
• Field current controller or field current precontrol is not optimized or optimized badly (check P112, P253 to P256 or
execute a current controller optimization run (P051=25))

11 A lower field current limit of ≥ 50% of P102 (IF,motor) is applied
(for this reason, it is not possible to plot a minimum of 9 field weakening measuring points)
Possible cause:
• P103 ≥ 50% of P102
Check P614 !

12 The drive has reached the positive torque limit even though the applied field current setpoint is still ≥ 50% of P102
(IF,motor)
Possible cause:
• Armature current is very “unsteady”, e.g. due to high speed controller P gain setting in P225 (on drive with high integral-
action time). In this case, setting a lower actual speed filtering value in P200 and execution of another speed controller
optimization run (P051=26) may help.
• Check torque limits

13 The drive has reached the positive armature current limit even through the applied field current setpoint is still ≥ 50% of
P102 (IF,motor)
Possible cause:
• Armature current is very “unsteady”, e.g. due to high speed controller P gain setting in P225 (on drive with high integral-
action time). In this case, setting a lower actual speed filtering value in P200 and execution of another speed controller
optimization run (P051=26) may help
• Check armature current limits

14 The speed has changed by more than 12.5% at a constant speed setpoint even through the applied field current setpoint is
still ≥ 50% of P102 (IF,motor)
Possible cause: as for fault value 12

15 The EMF setpoint is too small to plot a field characteristic
EMFset = UA – IA,motor * RA = P101 – P100 * P110 < 10% of 1.35 * P078.i001
(e.g. P078.i001 = 400 V . . . minimum EMFset = 54 V)

16 Field weakening operation is not allowed in operation without a tachometer (P083=3)

17 The field current controller cannot be optimized because the field circuit time constant cannot be determined (actual field
current does not decay after switch-off to below 0.95*initial value within approximately 1s or to below 0.8 * 0.95*initial
values within approximately 2 s)
Possible cause:
• Setting in P103 is too high
• Field circuit inductance is too high
• Fault in actual field current sensing circuit (gating board or A7001 electronics board defective)
• Ratio r073.02 / P102 is too high (change P076.02 if necessary)

18 Field weakening range is too wide, i.e. during power-up (at full field) to a speed setpoint of +10% nmax , the |EMK| is > 77%
of setpoint EMF (P101 – P100 * P110)
Possible cause:
• Maximum speed setting is incorrect
• Pulse encoder parameters are incorrect (P140 to P143)
• Parameters for tachometer adaptation are incorrect (P741)
• Setpoint EMF is not correct (P101, P100, P110)
• An excessively high load torque (in positive or negative direction, e.g. a suspended load) causes the drive to rotate, one
of the armature current or torque limits may be parameterized too low

19 A steady-state actual speed of +10%, +20%, +30% . . . or +100% of the maximum speed cannot be reached within 3
minutes (or maximum value of the three set acceleration times) in speed-controlled operation (the speed setpoint/actual
value difference averaged over 90 firing cycles must equal <0.1% nmax for a specific time period)
Possible cause:
• Acceleration time is set too low (P303, P307, P311)
• Drive is blocked
• An excessively high load torque (in positive or negative direction, e.g. a suspended load) causes the drive to rotate, one
of the armature current or torque limits may be parameterized too low
• Poor speed controller setting (P225, P226, P228) or speed controller is parameterized as pure P controller or with
droop
• A band elimination filter (P201, P202 or P203, P204) is active
• Command “Ramp-function generator enable” =0 or ”Ramp-function generator STOP” =1 is applied
• “Field weakening operation” (P081 = 1) is not parameterized

20 Current limit is too low
(With speed controller optimization run: Less than 30% or 45% of P100 (IA,motor) + the armature current required for zero
speed,
With optimization run for friction moment and moment of inertia compensation: Less than 20% of P100 (IA, motor) + the
armature current required for a steady-state speed corresponding to 10% of maximum speed)

21 Field weakening range is too wide (nact < +7% nmax produces |EMF| > 54% setpoint EMF)
(setpoint EMF= K289= P101 – P100 * P110)
Possible cause:
• Maximum speed setting is incorrect
• Pulse encoder parameters are incorrect (P140 to P143)
• Parameters for tachometer adaptation are incorrect (P741)
• Setpoint EMF is not correct (P101, P100, P110)
• Caution:
Even a high absolute negative actual speed value can produce an | EMF | of > 54% setpoint EMF

22 With speed controller optimization run:
With an acceleration current equaling 20% or 30% of P100 (IA, motor) + armature current required for zero speed or
With optimization run for friction moment and moment of inertia compensation:
With an acceleration current equaling the current required to achieve a steady-state speed of 10% of maximum speed +
20% of P100 (IA, motor), the maximum speed cannot be reached within 45s +7%
Possible cause:
• Centrifugal mass is too large
• Drive is blocked, heavily speed-dependent or excessively high load torque
• “Active” load is attempting to maintain a certain speed
Possible remedy:
• Increase P100 while the optimization run is in progress in order to raise the applied acceleration current during
optimization (during the speed controller optimization run, a maximum of 45% of IA, motor (+ armature current for zero
speed) is applied as the armature current setpoint, IA,motor (P100) can thus be increased to 2.2 times the value at
maximum without exceeding 100% IA, motor during optimization)

23 With speed controller optimization run:
With an acceleration current equaling 20% or 30% of P100 (IA, motor) + armature current required for zero speed or
With optimization run for friction moment and moment of inertia compensation:
With an acceleration current equalling the current required to achieve a steady-state speed of 10% of maximum speed +
20% of P100 (IA, motor), the maximum speed or 100% of setpoint EMF cannot be reached within 90s +13%
Possible cause:
• Flywheel mass is too large
• Drive is blocked, heavily speed-dependent or excessively high load torque
• “Active” load is attempting to maintain a certain speed
Possible remedy:
• Increase P100 while the optimization run is in progress in order to raise the applied acceleration current during
optimization (during the speed controller optimization run, a maximum of 45% of IA, motor (+ armature current for zero
speed) is applied as the armature current setpoint, IA,motor (P100) can thus be increased to 2.2 times the value at
maximum without exceeding 100% IA, motor during optimization)

24 With speed controller optimization run:
The actual speed does not drop to below +2% of maximum speed or to below the speed threshold nmin set in P370 within 2
minutes
With optimization run for field weakening:
The actual speed does not drop to below +2% of maximum speed or to below the speed threshold nmin set in P370 within
10 minutes
With optimization run for friction moment and moment of inertia compensation:
The actual speed does not drop to below +2% of maximum speed or to below the speed threshold nmin set in P370 within
11 or 2 minutes
Possible cause:
• Single-quadrant drive coasts to a standstill too slowly

25 The average armature current required for the speed range from +7% to approximately +13% of maximum speed to cover
the friction and/or steady-state load torque cannot be calculated
Possible cause:
• Drive with very little friction or very small integral-action time and, as a result of the very short measuring time,
computational inaccuracies during evaluation
• Distorted or disturbed actual speed value
• Large flywheel mass that is coupled to the drive via long shaft with high torsion, possibly via a
coupling with large amount of play
Possible remedy:
• Reduce P100 for duration of the optimization run to decrease the acceleration current applied during optimization and
thus to lengthen the measuring time

26 Load torque too high (nset =0% nmax results in nict ≥ 40% nmax) (actual speed value is averaged over 90 firing cycles,
speed monitoring at ≥ 40% nmax does not start for 1s after application of speed setpoint of nset=0)
Possible cause:
• An excessively high load torque (in a positive or negative direction, e.g. suspended load) causes the drive to rotate (the
speed controller parameters are parameterized according to the factory setting during this run)
• One of the armature current or torque limits is parameterized too low (the motor field may not be reaching full field
strength fast enough with the result that the initial motor torque is too low)
• Maximum speed setting is incorrect
• Pulse encoder parameters are incorrect (P140 to P143)
• Parameters for tachometer adjustment are not correct (P741)

27 Load torque is too high (nset=0% nmax results in |EMF| >100% setpoint EMF) (EMF monitoring at ≥ (P101 – P100 * P110)
does not start for 1 s after application of speed setpoint of nset=0)
Possible cause:
• An excessively high load torque (in a positive or negative direction, e.g. suspended load) causes the drive to rotate (the
speed controller parameters are parameterized according to the factory setting during this run)
• One of the armature current or torque limits is parameterized too low (the motor field may not be reaching full field
strength fast enough with the result that the initial motor torque is too low)
• Maximum speed setting is incorrect
• Pulse encoder parameters are incorrect (P140 to P143)
• Parameters for tachometer adjustment are not correct (P741)
• Setpoint EMF settings are incorrect (P101, P100, P110)

28 A steady-state actual speed corresponding to 0% of maximum speed cannot be reached within 0 s in speed-controlled
operation (the speed setpoint/actual value difference averaged over 90 firing cycles must be <1.0% nmax for a total of 4s)
Possible cause: As for fault value 26

29 The calculated armature circuit inductance is greater than 327.67 mH, therefore P111 = 327,67 mH has been set. All other
parameters (the current controller parameters P155 and P156 too) have been set correctly despite that. (For the real
armature circuit inductance in mH, see r047.i010).
Possible cause:
•e.g. field supply from the armature terminals

30 The calculated armature circuit inductance is greater than 327.67 mH and the calculated armature circuit resistance is
greater than 32.767 Ω, therefore P111 = 327,67 mH and P110 = 32,767 Ω has been set. All other parameters have also
been set. However, the values of the current controller parameters P155 and P156 might differ from the optimum setting.
Possible cause:
•e.g. field supply from the armature terminals

31 The calculated armature circuit resistance is greater than 32.767 Ω, therefore P110 = 32,767 Ω has been set. All other
parameters have also been set. Possibly the calculated P111 and therefore also the current controller parameters P155
and P156 have been distorted by the limitation in P110 .
Possible cause:
•e.g. field supply from the armature terminals

50 The protocol selection for basic-device interface G-SST2 has not been set to communication with the SIMOREG CCP.
Possible remedy:
Set P790 to 6

51 The protocol counter of the error-free telegrams r799.i001 is not incremented. Communication with the SIMOREG CCP
does not take place.
Possible cause:
e.g. defective cabling for the peer-to-peer connection at X172

52 Incorrect MLFB identification number of the SIMOREG CCP (n570 < 250, see r047.i003)
Please contact your nearest SIEMENS agent

53 The electric strength of the SIMOREG CCP is too low. The SIMOREG device’s rated input voltage set in P078.i001 (see
r047.i003 in V) is higher than the rated supply voltage of the SIMOREG CCP (see r047.i004 in V). It is not permissible to
operate the SIMOREG CCP in this hardware configuration.

54 It is not possible to set parameter U578. The calculated voltage setpoint for precharging the surge absorbing capacitors in
the SIMOREG CCP (see r047.i003 in V) is higher than the rectifier average of supply voltage actually being applied
(minimum value in line with the lower tolerance limit in accordance with P351(see r047.i004 in V)
See also the description for parameter U578 in the SIMOREG CCP operating instructions

55 The maximum energy – to be reduced during extinguishing – in the armature circuit (see r047.i003 in kJ) is higher than the
energy that can be absorbed in the chopper resistors of the SIMOREG CCP (see r047.i003 in kJ). The selected
SIMOREAG CCP is not suitable for the existing hardware configuration.
See also step 5 in the section entitled “Commissioning steps” of the operating instructions of the SIMOREG CCP.

56 The value set at parameter P111 for the armature inductance is 0
Possible cause:
The optimization run for the current controller has not been carried out.

57 In the existing software of the SIMOREG device, there are still no setting data for operation with SIMOREG CCP.
Possible remedy:
Update the SIMOREG software

as a result
of external
cause
This fault message is activated when the converter ceases operating in the RUN state (state I, II or –) during an optimization run (and thus in response to every FAULT) or if the EMERGENCY STOP or SHUTDOWN command is applied. The optimization run is aborted. Only those parameters which had been fully optimized prior to activation of the fault message are altered. When the STANDSTILL command is applied, this fault message is not activated if the optimization run for field weakening is interrupted after the 1st field weakening measuring point has been recorded or, in the case of the optimization run for friction and moment of inertia compensation, after the measuring point at 10% maximum speed has been determined. In these cases, the run may be interrupted by STANDSTILL so as to be able to complete the run in several stages (by repeated restarts) for a limited travel path.

Fault value: r047 Index 002 to 016:
1. Run was aborted because converter is no longer operating in RUN mode (For example, this can occur when r047i002=2 in the case of a motor with a very high field circuit time constant
→ For help, see P051 = 26 in chapter 7.5)
2. Run was aborted because EMERGENCY STOP command was applied (speed controller setpoint =0)
3. Run was aborted because STANDSTILL command was applied (ramp-function generator setpoint=0)
4. Operation has been aborted because P051 was changed during the optimization run
5. Run was aborted because SWITCH-ON command was not applied within 30 s of selection of optimization run
6. Operation has been aborted because the OPERATING ENABLE command was not entered within 1 minute of selection of the optimization run.
7. Operation has been aborted because converter was not in operating state < o7.2 15 s after selection of the optimization run with P051 = 25, 26, 27 or 28 (input of OFF1 command may have been forgotten)

Fault message
from thyristor
check function
This fault message can be activated only if the thyristor check is activated via parameter P830.

If “Thyristor defective” or “Thyristor unable to block” is signaled, then the relevant thyristor module must be replaced.
Possible causes for irreparable damage to thyristors:
– Interruption in snubber circuit
– Current controller and precontrol are not optimized (excessive current peaks)
– Inadequate cooling (e.g. fan is not operating, ambient temperature is too high, fan is rotating in wrong direction (incorrect phase sequence), inadequate air supply, heatsink is very dirty)
– Excessive voltage peaks in incoming supply system
– External short circuit or fault to ground (check armature circuit)

If “Thyristor unable to block” is signaled, the cause can generally be attributed to a firing circuit fault, rather than to a defective thyristor.
Possible causes:
– Firing pulse cable to relevant thyristor is interrupted
– Ribbon cable X101 or X102 is incorrectly inserted or interrupted
– Defective electronics or gating board
– Internal interruption in gating cable in thyristor module

The designations of the firing cables and associated thyristors can be found in Section 6.4 (power connections).

Fault in
parameter
memory
Software monitoring of correct functioning of the EEPROM module (non-volatile memory) on the A7009 board. The EEPROM values contains all data which must be protected in the case of a power failure (i.e. parameter values and process data which must remain stored during power failures).

The following are monitored:
– Connection between the A7001 electronics board and the EEPROM on the A7009 backplane wiring assembly
– Whether the parameter values stored on the EEPROM are within the permissible value range
– Whether data are being correctly stored on the EEPROM. For this purpose, values are read and checked for correctness after they are transferred to the module
– Whether the checksum of the non-volatile process data in the EEPROM is correct

Possible causes for all fault types:
– Excessive EMC-related interference is present (e.g. due to unprotected contactors, unscreened cables, loose shield connections)

A035
Drive blocked
The monitoring function responds if the following conditions are fulfilled for longer than the time set in parameter P355:
– Positive or negative torque or armature current limit reached
– Armature current is greater than 1% of converter rated armature DC current
– The actual speed value is less than 0.4% of maximum speed
A036
No armature
current can
flow
This monitoring function responds if the armature firing angle is at the rectifier stability limit for more than 500 ms and the armature current is less than 1% of the converter rated armature DC current.
A037
I2t motor
monitor has
responded
The alarm is activated when the calculated I2t value of the motor reaches the value which corresponds to the final temperature at 100% of permissible continuous motor current (= P113*P100).
A038
Overspeed
The monitoring function responds if the actual speed value (selected in P595) exceeds the positive (P512) or negative (P513) threshold by 0.5%.

Possible causes
– Lower current limit has been input
– Current-controlled operation
– P512, P513 are set too low
– Tachometer cable contact fault in operation close to maximum speed
A039
I2t value
of power
section
too high
This alarm is activated if the permissible I2t value for the relevant power section is reached. At the same time, the current limit is set to P077 * 100% of the converter rated DC current. This limit is not cancelled again until the setpoint drops below 100% of the converter rated DC current. See also Fault F039 and Parameter P075.
A043
Automatic field
current reduction
if EMF is too
high in operation
1. This alarm is active only when parameter P272=1 and activated if the following equation applies to firing angle α (armature) before limitation (K101):
– α > (αW (inverter stability limit acc. to P151) – 5 degrees) or , at a low (pulsating) current
– α > (165 degrees – 5 degrees)
– AND armature current setpoint K0118 filtered with P190.F is > 1% of r072.002

2. The field is reduced simultaneously with A043, implemented through control of the armature firing angle to (αW (or 165 degrees)
– 5 degrees) using a P controller whose output reduces the EMF controller setpoint. For this reason, “Field weakening operation through internal EMF control” (PO81=1) must be parameterized.

3. When a change in torque direction is requested, both torque directions are inhibited until the calculated control angle (K101) is <165 degrees for the armature current requested in the new torque direction, i.e. until the field, and thus the EMF, have been reduced accordingly.
4. See also parameter P082.
