  • Technology unit selection (p0595) before changing the reference parameter p0596, set p0595 = 1.


A01035 (F)

ACX: Parameter back-up file corrupted

Cause: When the Control Unit is booted, no complete data set was found from the parameter back-up files. The last time that the parameterization was saved, it was not completely carried out.

It is possible that the backup was interrupted by switching off or withdrawing the memory card.

Alarm value (r2124, interpret hexadecimal): ddccbbaa hex:

aa = 01 hex: Power up was realized without data backup. The drive is in the factory setting.

aa = 02 hex: The last available internal backup data record was loaded. The parameterization must be checked. It is recommended that the parameterization is downloaded again.

aa = 03 hex: The last available data record from the memory card was loaded. The parameterization must be checked.

aa = 04 hex: An invalid data backup was loaded from the memory card into the drive. The drive is in the factory setting.

F01036 (A)

ACX: Parameter back-up file missing

Cause: When downloading the device parameterization, a parameter back-up file PSxxxyyy.ACX associated with a drive object cannot be found.

Fault value (r0949, interpret hexadecimal):

Byte 1: yyy in the file name PSxxxyyy.ACX

yyy = 000 –> consistency back-up file

yyy = 001 … 062 –> drive object number

yyy = 099 –> PROFIBUS parameter back-up file

Byte 2, 3, 4: Only for internal Siemens troubleshooting.



Remedy: If you have saved the project data using the commissioning software, carry out a new download for your project.

Save using the function “Copy RAM to ROM” or with p0971 = 1.

This means that the parameter files are again completely written into the non-volatile memory.

Note: If the project data have not been backed up, then a new first commissioning is required.
F01038 (A)

ACX: Loading the parameter back-up file unsuccessful

Cause: An error has occurred when downloading PSxxxyyy.ACX or PTxxxyyy.ACX files from the non-volatile memory.

Fault value (r0949, interpret hexadecimal):

Byte 1: yyy in the file name PSxxxyyy.ACX

yyy = 000 –> consistency back-up file

yyy = 001 … 062 –> drive object number

yyy = 099 –> PROFIBUS parameter back-up file

Byte 2:

255: Incorrect drive object type.

254: Topology comparison unsuccessful -> drive object type was not able to be identified.

Reasons could be:

– Incorrect component type in the actual topology

– Component does not exist in the actual topology.

– Component not active.

Additional values: Only for internal Siemens troubleshooting.

Byte 4, 3: Only for internal Siemens troubleshooting.



Remedy:

  • If you have saved the project data using the commissioning software, download the project again. Save using the function “Copy RAM to ROM” or with p0971 = 1. This means that the parameter files are again completely written to the non-volatile memory.

  • Replace the memory card or Control Unit.


F01039 (A)

ACX: Writing to the parameter back-up file was unsuccessful

Cause: Writing to at least one parameter back-up file PSxxxyyy.*** in the non-volatile memory was unsuccessful.

– in the directory /USER/SINAMICS/DATA/ at least one parameter back-up file PSxxxyyy.*** has the “read only” file attribute and cannot be overwritten.

– there is not sufficient free memory space available.

– the non-volatile memory is defective and cannot be written to.

Fault value (r0949, interpret hexadecimal): dcba hex

a = yyy in the file names PSxxxyyy.***

a = 000 –> consistency back-up file

a = 001 … 062 –> drive object number

a = 099 –> PROFIBUS parameter back-up file

b = xxx in the file names PSxxxyyy.***

b = 000 –> data save started with p0971 = 1

b = 010 –> data save started with p0971 = 10

b = 011 –> data save started with p0971 = 11

b = 012 –> data save started with p0971 = 12

d, c: Only for internal Siemens troubleshooting.



Remedy:

  • Check the file attribute of the files (PSxxxyyy.***, CAxxxyyy.***, CCxxxyyy.***) and, if required, change from “read only” to “writeable”.

  • Check the free memory space in the non-volatile memory. Approx. 80 kbyte of free memory space is required for every drive object in the system.

  • Replace the memory card or Control Unit.


F01040

It is not possible to write to file

Cause: It is not possible to write into a write-protected file (PSxxxxxx.acx). The write request was interrupted.

Alarm value (r2124, interpret decimal): Drive object number.



Remedy: Check whether the “write protected” attribute has been set for the files in the non-volatile memory under …/USER/SINAMICS/DATA/… When required, remove write protection and save again (e.g. set p0971 to 1).
F01054

CU: System limit exceeded

Cause: At least one system overload has been identified.

Fault value (r0949, interpret decimal):

1: Computing time load too high (r9976[1]).

5: Peak load too high (r9976[5]).

Note: As long as this fault is present, it is not possible to save the parameters (p0971).



Remedy: For fault value = 1, 5:

  • Reduce the computing time load of the drive unit (r9976[1] and r9976[5]) to under 100 %.

  • Check the sampling times and adjust if necessary (p0115, p0799, p4099).

  • Deactivate function modules.

  • Deactivate drive objects.

  • Remove drive objects from the target topology.

  • Note the DRIVE-CLiQ topology rules and if required, change the DRIVE-CLiQ topology.


When using the Drive Control Chart (DCC) or free function blocks (FBLOCKS), the following applies:

  • The computing time load of the individual runtime groups on a drive object can be read out in r21005 (DCC) or r20005 (FBLOCKS).

  • If necessary, the assignment of the runtime group (p21000, p20000) can be changed in order to increase the sampling time (r21001, r20001).

  • If necessary, reduce the number of cyclically calculated blocks (DCC) and/or function blocks (FBLOCKS).


A01066

Buffer memory: 70% fill level reached or exceeded

Cause: The non-volatile buffer memory for parameter changes is filled to at least 70%.

This can also occur if the buffer memory is active (p0014 = 1) and parameters are continually changed via a fieldbus system.



Remedy:

  • If required, deactivate and clear the buffer memory (p0014 = 0).

  • If required, clear the buffer memory (p0014 = 2).


In the following cases, the entries in the buffer memory are transferred into the ROM and then the buffer memory is cleared:

  • p0971 = 1

  • switch-off/switch-on Control Unit


See also: p0014 (Buffer memory mode)
A01067

Buffer memory: 100 % fill level reached

Cause: The non-volatile buffer memory for parameter changes is filled to 100%.

All additional parameter changes will no longer be taken into account in the non-volatile buffer memory. However, parameter changes can still be made in the volatile memory (RAM).

This can also occur if the buffer memory is active (p0014 = 1) and parameters are continually changed via a fieldbus system.



Remedy:

  • If required, deactivate and clear the buffer memory (p0014 = 0).

  • If required, clear the buffer memory (p0014 = 2).


In the following cases, the entries in the buffer memory are transferred into the ROM and then the buffer memory is cleared:

  • p0971 = 1

  • switch-off/switch-on Control Unit


See also: p0014 (Buffer memory mode)
F01068

  • Insert a memory card without parameter backup and carry out a POWER ON.

  • If required, withdraw the memory card and carry out POWER ON.

  • Save the parameters (p0971 = 1).


F01072

Memory card restored from the backup copy

Cause: The Control Unit was switched-off while writing to the memory card. This is why the visible partition became defective.

After switching on, the data from the non-visible partition (backup copy) were written to the visible partition.



Remedy: Check that the firmware and parameterization is up-to-date.
A01073 (N)

POWER ON required for backup copy on memory card

Cause: The parameter assignment on the visible partition of the memory card has changed.

In order that the backup copy on the memory card is updated on the non-visible partition, it is necessary to carry out a POWER ON or hardware reset (p0972) of the Control Unit.

Note: It is possible that a new POWER ON is requested via this alarm (e.g. after saving with p0971 = 1).



Remedy:

  • Carry out a POWER ON (power off/on) for the Control Unit.

  • Carry out a hardware reset (RESET button, p0972).


A01098

Remedy:

  • check the BICO interconnections for the limit switch signals.

  • check the sensors.


A07353
Drive: DC quantity control deactivated

Cause: The DC quantity control has deactivated itself. The manipulated variable was at its limit.



Remedy:

  • Optimize the DC quantity controller (Kp, Tn, bandwidth, PT2 filter).


F07390
Drive: DC link capacitor forming fault

Cause: The “DC link capacitor forming” function was canceled with fault. The expected DC link voltage is out of tolerance.



Remedy:

  • check drive device (supply voltage, terminals, …).

  • set activation/duration again (p3380 > 0).

  • restart forming.


A07391
Drive: DC link capacitor forming active

Cause: The “DC link capacitor forming” function is active.



Remedy:

  • Not necessary. The alarm is automatically withdrawn after forming has been completed.


A07400 (N)
Drive: DC link voltage maximum controller active

Cause: The DC link voltage controller has been activated because the upper switch-in threshold has been exceeded. The ramp-down times are automatically increased.



Remedy:

  • If controller is not to intervene: increase the ramp-down times or switch off the Vdc_max controller.

  • If ramp-down times are not to be changed: use a chopper or regenerative feedback unit.


A07401 (N)
Drive: DC link voltage maximum controller deactivated

Cause: The Vdc_max controller can no longer maintain the DC link voltage below the limit value and was therefore switched out.



Remedy:

  • check whether the input voltage is within the permissible range.

  • check whether the load duty cycle and load limits are within the permissible limits.


A07402 (N)
Drive: DC link voltage minimum controller active

Cause: The DC link voltage controller has been activated as the lower switch-in threshold has been undershot. The kinetic energy of the motor is used to buffer the DC link.



Remedy:

  • The alarm disappears when power supply returns.


F07404
Drive: DC link voltage monitoring Vdc_max

Cause: The monitoring of the DC link voltage p1284 has responded (only U/f control).

– motor data/configuration mismatch.

– power unit defective.



Remedy:

  • connect the motor or check the motor contactor.

  • check the motor parameterization and the connection type (star-delta).

  • check the DC link voltage.

  • check the power unit.


F07411
Drive: Flux setpoint not reached when building up excitation

  • For fault cause = 2: switch-on flux build-up control or shut down quick magnetizing.

  • For fault cause = 3: Re-parameterize Rs identification or shut down quick magnetizing.


F07426 (A)
Technology controller actual value limited

Cause: The actual value for the technology controller, interconnected via connector input p2264, has reached a limit.



Remedy:

  • adapt the limits to the signal level (p2267, p2268).

  • check the actual value normalization (p0595, p0596).


A07427
Motor switch-in alarm

Cause:

1: Technology controller not active or used for main setpoint.

2: Operating time limits exceeded in at least one external motor.



Remedy:

  • For alarm value = 1: enable technology controller, set mode p2251 = 0.

  • For alarm value = 2: increase p2381, p2382 or set p2380 = 0.


A07428 (N)
Technology controller parameterizing error

Cause: The technology controller has a parameterizing error. The upper output limit in p2291 is set lower than the lower output limit in p2292.



Remedy:

  • Set the output limit in p2291 higher than in p2292.


F07435 (N)
Drive: Setting the ramp-function generator for sensorless vector control

Cause: During operation with sensorless vector control the ramp-function generator was stopped. An internal setting command caused the setpoint speed to be frozen.



Remedy:

  • deactivate the holding command for the ramp-function generator (p1141).

  • suppress the fault (p2101, p2119).


F07436 (A)

  • check the scaling of the actual value signal.

  • check the signal source setting.


A07444
PID autotuning is activated

Cause: Automatic setting of the PID controller parameters (PID autotuning) was activated.



Remedy:

  • Not necessary. This alarm is automatically withdrawn after the PID autotuning has been completed.


F07445
PID autotuning canceled

Cause: The PID autotuning was canceled as a result of an error.



Remedy:

  • increase the offset.

  • check system configuration.


A07530
Drive: Drive Data Set DDS not present

Cause: The selected drive data set is not available. The drive data set was not changed over.



Remedy:

  • select the existing drive data set.

  • set up additional drive data sets.


A07531

Drive: Command Data Set CDS not present

Cause: The selected command data set is not available (p0836 > p0170). The command data set was not changed over.

See also: p0810, p0811, p0812, p0813, r0836



Remedy:



  • Select the existing command data set.

  • Set up additional command data sets.


F07800

Drive: No power unit present

Cause: The power unit parameters cannot be read or no parameters are stored in the power unit.

Note:

This fault also occurs if an incorrect topology was selected in the commissioning software and this parameterization is then downloaded to the Control Unit.

See also: r0200 (Power unit code number actual)



Remedy:



  • Carry out a POWER ON (switch-off/switch-on) for all components.

  • Check the power unit and replace if necessary.

  • Check the Control Unit, and if required replace it.

  • After correcting the topology, the parameters must be again downloaded using the commissioning software.


F07801

Drive: Motor overcurrent

Cause: The permissible motor limit current was exceeded.

– effective current limit set too low.

– current controller not correctly set.

– U/f operation: Up ramp was set too short or the load is too high.

– U/f operation: Short-circuit in the motor cable or ground fault.

– U/f operation: Motor current does not match current of power unit.

– Switch to rotating motor without flying restart function (p1200).

Note: Limit current = 2 x minimum (p0640, 4 x p0305 x p0306) >= 2 x p0305 x p0306



Remedy:



  • Check the current limits (p0640).

  • Vector control: Check the current controller (p1715, p1717).

  • U/f control: Check the current limiting controller (p1340 … p1346).

  • Increase the up ramp (p1120) or reduce the load.

  • Check the motor and motor cables for short-circuit and ground fault.

  • Check the motor for the star-delta configuration and rating plate parameterization.

  • Check the power unit and motor combination.

  • Choose “flying restart” function (p1200) if switched to rotating motor.


F07802

Drive: Infeed or power unit not ready

Cause: After an internal switch-on command, the infeed or drive does not signal ready.

– Monitoring time is too short.

– DC link voltage is not present.

– Associated infeed or drive of the signaling component is defective.

– Supply voltage incorrectly set.



Remedy:



  • Increase the monitoring time (p0857).

  • Ensure that there is a DC link voltage. Check the DC link busbar. Enable the infeed.

  • Replace the associated infeed or drive of the signaling component.

  • Check the line supply voltage setting (p0210).


See also: p0857 (Power unit monitoring time)
A07805 (N)

Drive: Power unit overload I2t

Cause: Alarm threshold for I2t overload (p0294) of the power unit exceeded.

The response parameterized in p0290 becomes active.

See also: p0290



Remedy:



  • Reduce the continuous load.

  • Adapt the load duty cycle.

  • Check the assignment of the motor and power unit rated currents.


F07806

Drive: Regenerative power limit exceeded (F3E)

Cause: For blocksize power units, types PM250 and PM260, the regenerative rated power r0206[2] was exceeded for more than 10 s.

See also: r0206, p1531



Remedy:



  • Increase the down ramp.

  • Reduce the driving load.

  • Use a power unit with a higher regenerative feedback capability.

  • For vector control, the regenerative power limit in p1531 can be reduced so that the fault is no longer triggered.


F07807

Drive: Short-circuit/ground fault detected

Cause: A phase-phase short-circuit or ground fault was detected at the motor-side output terminals of the converter.

Fault value (r0949, interpret decimal):

1: Short-circuit, phase UV.

2: Short-circuit, phase UW.

3: Short-circuit, phase VW.

4: Ground fault with overcurrent.

5: Motor cable phase U interrupted

6: Motor cable phase V interrupted

7: Motor cable phase W interrupted

8: Short-circuit with hardware shutdown

1yxxx: Ground fault with current in phase U detected (y = pulse number, xxxx = component of the current in phase V in per mille).

2yxxx: Ground fault with current in phase V detected (y = pulse number, xxxx = component of the current in phase U in per mille).

Note:

Also when interchanging the line and motor cables is identified as a motor-side short circuit.

The ground fault test only functions when the motor is stationary.

Connecting to a motor that is either not de-energized or partially de-energized is possibly detected as ground fault.



Remedy:



  • Check the motor-side converter connection for a phase-phase short-circuit.

  • Rule-out interchanged line and motor cables.

  • Check for a ground fault.

  • Check the motor cable connections.


For a ground fault the following applies:

  • Do not enable the pulses when connecting to a rotating motor without the “Flying restart” function activated (p1200).

  • Increase the de-energization time (p0347).

  • Increase pulse cancellation delay time (p1228) to ensure standstill.

  • If required, deactivate the monitoring (p1901).


F07810

Drive: Power unit EEPROM without rated data

Cause: No rated data are stored in the power unit EEPROM.

  • Acknowledge fault.


A07891

Drive: Load monitoring pump/fan blocked

Cause: The load monitoring is configured for a pump or fan (p2193 = 4, 5).

The monitoring function detects when the pump/fan is blocked.

It is possible that the blocking torque threshold (p2168) is set too low (e.g. heavy duty starting).

See also: p2165, p2168, p2181, p2193



Remedy:



  • Check whether the pump/fan is blocked, and if blocked, then resolve the problem.

  • Check that the fan can freely move, and if necessary, resolve the problem.

  • Adapt the parameterization corresponding to the load (p2165, p2168).


A07892

Drive: Load monitoring pump/fan no load condition

Cause: The load monitoring is configured for a pump or fan (p2193 = 4, 5).

The monitoring function detects when the pump/fan is operating under no load conditions.

The pump is running in the dry state (no medium to be pumped) – or the fan has a broken belt.

It is possible that the detection torque threshold is too low (p2191).

See also: p2181, p2191, p2193



Remedy:



  • For a pump, check the medium being pumped, and if required, provide the medium.

  • For a fan, check the belt, and if required, replace.

  • If necessary, increase the detection torque threshold (p2191).


A07893

Drive: Load monitoring pump leakage

Cause: The load monitoring is configured for a pump (p2193 = 4).

The monitoring function detects a leak in the pump circuit.

In this case, the pump requires a torque that is lower than in normal operation to pump the reduced quantity.

See also: p2181, p2182, p2183, p2184, p2186, p2188, p2190, p2193



Remedy:



  • Remove the leak in the pump circuit.

  • For a nuisance trip, reduce the torque thresholds of the leakage characteristic (p2186, p2188, p2190).


F07894

Drive: Load monitoring pump/fan blocked

Cause: The load monitoring is configured for a pump or fan (p2193 = 4, 5).

The monitoring function detects when the pump/fan is blocked.

It is possible that the blocking torque threshold (p2168) is set too low (e.g. heavy duty starting).

See also: p2165, p2168, p2181, p2193



Remedy:



  • Check whether the pump/fan is blocked, and if blocked, then resolve the problem.

  • Check that the fan can freely move, and if necessary, resolve the problem.

  • Adapt the parameterization corresponding to the load (p2165, p2168).


F07895

Drive: Load monitoring pump/fan no load condition

Cause: The load monitoring is configured for a pump or fan (p2193 = 4, 5).

The monitoring function detects when the pump/fan is operating under no load conditions.

The pump is running in the dry state (no medium to be pumped) – or the fan has a broken belt.

It is possible that the detection torque threshold is too low (p2191).

See also: p2181, p2191, p2193



Remedy:



  • For a pump, check the medium being pumped, and if required, provide the medium.

  • For a fan, check the belt, and if required, replace.

  • If necessary, increase the detection torque threshold (p2191).


F07896

Drive: Load monitoring pump leakage

Cause: The load monitoring is configured for a pump (p2193 = 4).

The monitoring function detects a leak in the pump circuit.

In this case, the pump requires a torque that is lower than in normal operation to pump the reduced quantity.

See also: p2181, p2182, p2183, p2184, p2186, p2188, p2190, p2193



Remedy:



  • Remove the leak in the pump circuit.

  • For a nuisance trip, reduce the torque thresholds of the leakage characteristic (p2186, p2188, p2190).


F07900 (N, A)

Drive: Motor blocked

Cause: Motor has been operating at the torque limit longer than the time specified in p2177 and below the speed threshold in p2175.

This signal can also be triggered if the speed is oscillating and the speed controller output repeatedly goes to its limit.

It may also be the case that thermal monitoring of the power unit reduces the current limit (see p0290), thereby causing the motor to decelerate.

See also: p2175, p2177



Remedy:



  • Check that the motor can freely move.

  • Check the effective torque limit (r1538, r1539).

  • Check the parameter, message “Motor blocked” and if required, correct (p2175, p2177).

  • Check the direction of rotation enable signals for a flying restart of the motor (p1110, p1111).

  • For U/f control: check the current limits and acceleration times (p0640, p1120).


F07901

Drive: Motor overspeed

Cause: The maximum permissible speed was either positively or negatively exceeded.

The maximum permissible positive speed is formed as follows: Minimum (p1082, CI: p1085) + p2162

The maximum permissible negative speed is formed as follows: Maximum (-p1082, CI: 1088) – p2162



Remedy:


The following applies for a positive direction of rotation:

  • Check r1084 and if required, correct p1082, CI:p1085 and p2162.


The following applies for a negative direction of rotation:

  • Check r1087 and if required, correct p1082, CI:p1088 and p2162.

  • Activate precontrol of the speed limiting controller (p1401.7 = 1).

  • Increase the hysteresis for the overspeed signal p2162. This upper limit is dependent upon the maximum motor speed p0322 and the maximum speed p1082 of the setpoint channel.


F07902 (N, A)

Drive: Motor stalled

Cause: The system has identified that the motor has stalled for a time longer than is set in p2178.

Fault value (r0949, interpret decimal):

1: Reserved.

2: Stall detection using r1408.12 (p1745) or via (r0084 … r0083).

See also: p2178 (Motor stalled delay time)



Remedy:


Steps should always be taken to ensure that both motor data identification and the rotating measurement were (if possible) carried out (see p1900, r3925).

  • Check whether the drive is in the open-loop speed control operating range (see p1755), or if the speed setpoint is still zero, whether the load alone caused the drive to stall. If yes, increase ramp-up time p1120, increase ramp-down time p1121 and increase current setpoint via p1610, p1611.

  • If the excitation time (p0346) of the induction motor was significantly reduced and the drive stalls when it is switched on and immediately run, then p0346 should be increased again.

  • Check whether a line phase failure is affecting power unit PM230, PM250, PM260.

  • Check whether the motor cables are disconnected (see A07929).


If there is no fault, then the fault tolerance (p1745) or the delay time (p2178) can be increased.

  • Check the current limits (p0640, r0067, r0289). If the current limits are too low, then the drive cannot be magnetized.

  • If the fault occurs with fault value 2 when the motor accelerates very quickly to the field weakening range, the deviation between the flux setpoint and flux actual value can be reduced and, in turn, the message prevented, by reducing p1596 or p1553.


A07903

Drive: Motor speed deviation

Cause: The absolute value of the speed difference from the setpoint (p2151) and the speed actual value (r2169) exceeds the tolerance threshold (p2163) longer than tolerated (p2164, p2166).

The alarm is only enabled for p2149.0 = 1.

Possible causes:

– The load torque is greater than the torque setpoint.

– When accelerating, the torque/current/power limit is reached. If the limits are not sufficient, then it is possible that the drive has been dimensioned too small.

– For active Vdc controller.

For U/f control, the overload condition is detected as the I_max controller is active.

See also: p2149 (Monitoring configuration)



Remedy:



  • Increase p2163 and/or p2166.

  • Increase the torque/current/power limits.

  • Deactivate alarm with p2149.0 = 0.


A07910 (N)

Drive: Motor overtemperature

Cause: KTY84/PT1000/PT100 or no sensor:

The measured motor temperature or the temperature of the motor temperature model 2 has exceeded the alarm threshold (p0604). The response parameterized in p0610 becomes active.

PTC or bimetallic NC contact:

The response threshold of 1650 Ohm was exceeded or the NC contact opened.

Alarm value (r2124, interpret decimal):

11: No output current reduction.

12: Output current reduction active.

See also: p0604, p0610



Remedy:



  • Check the motor load.

  • Check the motor ambient temperature.

  • Check KTY84/PT1000/PT100.

  • Check overtemperatures of the motor temperature model 2 (p0626 … p0628).

A07920

Drive: Torque/speed too low

Cause: For p2193 = 1: The torque deviates from the torque/speed envelope characteristic (too low).

For p2193 = 2: The speed signal from the external encoder (refer to p3230) deviates from the speed (r2169) (too low).

See also: p2181 (Load monitoring response)



Remedy:



  • Check the connection between the motor and load.

  • Adapt the parameterization corresponding to the load.


A07921

Drive: Torque/speed too high

Cause: For p2193 = 1: The torque deviates from the torque/speed envelope characteristic (too high).

For p2193 = 2: The speed signal from the external encoder (refer to p3230) deviates from the speed (r2169) (too high).



Remedy:



  • Check the connection between the motor and load.

  • Adapt the parameterization corresponding to the load.


A07922

Drive: Torque/speed out of tolerance

Cause: For p2193 = 1: The torque deviates from the torque/speed envelope characteristic.

For p2193 = 2: The speed signal from the external encoder (refer to p3230) deviates from the speed (r2169).



Remedy:



  • Check the connection between the motor and load.

  • Adapt the parameterization corresponding to the load.


F07923

Drive: Torque/speed too low

Cause: For p2193 = 1: The torque deviates from the torque/speed envelope characteristic (too low).

For p2193 = 2: The speed signal from the external encoder (refer to p3230) deviates from the speed (r2169) (too low).



Remedy:



  • Check the connection between the motor and load.

  • Adapt the parameterization corresponding to the load.


F07924

Drive: Torque/speed too high

Cause: For p2193 = 1: The torque deviates from the torque/speed envelope characteristic (too high).

For p2193 = 2: The speed signal from the external encoder (refer to p3230) deviates from the speed (r2169) (too high).



Remedy:



  • Check the connection between the motor and load.

  • Adapt the parameterization corresponding to the load.


F07925

Drive: Torque/speed out of tolerance

Cause: For p2193 = 1: The torque deviates from the torque/speed envelope characteristic.

For p2193 = 2: The speed signal from the external encoder (refer to p3230) deviates from the speed (r2169).



Remedy:



  • Check the connection between the motor and load.

  • Adapt the parameterization corresponding to the load.


A07926

Drive: Envelope curve parameter invalid

Cause: Invalid parameter values were entered for the envelope characteristic of the load monitoring.

The following rules apply for the speed thresholds: p2182 < p2183 < p2184

The following rules apply for the torque thresholds: p2185 > p2186, p2187 > p2188, p2189 > p2190

Load monitoring configuration and response must match.

It is not permissible that the individual load torque monitoring areas overlap.

Alarm value (r2124, interpret decimal): Number of the parameter with the invalid value.

The load torque monitoring has not been activated as long as the alarm is active.



Remedy:



  • Set the parameters for the load monitoring according to the applicable rules.

  • If necessary, deactivate the load monitoring (p2181 = 0, p2193 = 0).


A07927

DC braking active

Cause: The motor is braked with DC current. DC braking is active.

1) A message with response DCBRK is active. The motor is braked with the braking current set in p1232 for the duration set in p1233. If the standstill threshold p1226 is undershot, then braking is prematurely canceled.

2) DC braking has been activated at binector input p1230 with the DC braking set (p1230 = 4). Braking current p1232 is injected until this binector input becomes inactive.



Remedy:


Not necessary.

The alarm automatically disappears once DC braking has been executed.
A07929 (F)

Drive: No motor detected

Cause: The absolute current value is so small after enabling the inverter pulses that no motor is detected.

Note:
