Parker AC650G Drive

Fault Code and MeaningCause and Remedy
1
OVERVOLTAGE

Cause:
The drive internal dc link voltage is too high.



Remedy:

  • The supply voltage is too high.

  • Trying to decelerate a large inertia load too quickly; DECEL TIME too short.

  • The brake resistor is open circuit.


2
UNDERVOLTAGE

Cause:
DC link low trip.



Remedy:

  • Supply is too low/power down.


3
OVERCURRENT

Cause:
The motor current being drawn from the drive is too high.



Remedy:

  • Trying to accelerate a large inertia load too quickly; ACCEL TIME too short.

  • Trying to decelerate a large inertia load too quickly; DECEL TIME too short.

  • Application of shock load to motor.

  • Short circuit between motor phases.

  • Short circuit between motor phase and earth.

  • Motor output cables too long or too many parallel motors connected to the drive.

  • FIXED BOOST level set too high.


4
HEATSINK

Cause:
Drive heatsink temperature > 100ÂșC.



Remedy:

  • The ambient air temperature is too high.

  • Poor ventilation or spacing between drives.


5
EXTERNAL TRIP

Cause:
The external trip input is high.



Remedy:

  • Check configuration to identify the source of the signal (non-standard configuration).


6
INVERSE TIME

Cause:
A prolonged overload condition, exceeding the Inverse Time allowance, has caused the trip.



Remedy:

  • Remove the overload condition.


7
CURRENT LOOP

Cause:
A current of less than 1mA is present when 4-20mA setpoint is selected.



Remedy:

  • Look for a wire break.


8
MOTOR STALLED

Cause:
The motor has stalled (not rotating). Drive in current limit >200 seconds.



Remedy:

  • Motor loading too great.

  • FIXED BOOST level set too high.


9
ANIN FAULT

Cause:
AIN2 overload on terminal 3.



Remedy:

  • Overcurrent applied in Current mode to terminal 3.


10
BRAKE RESISTOR

Cause:
External dynamic brake resistor has been overloaded.



Remedy:

  • Trying to decelerate a large inertia too quickly or too often.


11
BRAKE SWITCH

Cause:
Internal dynamic braking switch has been overloaded.



Remedy:

  • Trying to decelerate a large inertia too quickly or too often.


12
DISPLAY/KEYPAD

Cause:
Keypad has been disconnected from drive whilst drive is running in Local Control.



Remedy:

  • Check if keypad was accidentally disconnected from drive (indicated over Comms, or by second keypad).


13
LOST COMMS

Cause:
Lost communications.



Remedy:

  • COMMS TIMEOUT parameter set too short.

  • Master device failed.

  • Wiring broken.

  • Incorrect Comms setup.


14
CONTACTOR FBK

Cause:
Contactor feedback signal lost.



Remedy:

  • Check connection to the terminal wired to “contactor closed” parameter in Sequencing Logic.


15
SPEED FEEDBACK

Cause:
Speed feedback error.



Remedy:

  • SPEED ERROR > 50.00% for 10 seconds.


16
AMBIENT TEMP

Cause:
Ambient temperature issue.



Remedy:

  • The ambient temperature in the drive is too high.


17
MOTOR OVERTEMP

Cause:
The motor temperature is too high.



Remedy:

  • Excessive load.

  • Motor voltage rating incorrect.

  • FIXED BOOST level set too high.

  • Prolonged operation of the motor at low speed without forced cooling.

  • Break in motor thermistor connection.


18
CURRENT LIMIT

Cause:
Software overcurrent trip. If the current exceeds 180% of stack rated current for 1 second, the drive will trip.



Remedy:

  • Caused by shock loads: Remove the shock load.

  • ACCEL TIME and/or FIXED BOOST set too high.

  • DECEL TIME set too low.


21
LOW SPEED OVER I

Cause:
The motor is drawing too much current (>100%) at zero output frequency.



Remedy:

  • FIXED BOOST level set too high.


22
10V FAULT

Cause:
10V fault detected.



Remedy:

  • +10V REF overload warning (terminal 4) – 10mA maximum.


25
DC LINK RIPPLE

Cause:
The dc link ripple voltage is too high.



Remedy:

  • Check for a missing input phase.


27
OVERSPEED

Cause:
Overspeed detected.



Remedy:

  • >150% base speed when in Sensorless Vector mode.


28
ANOUT FAULT

Cause:
AOUT overload on terminal 5.



Remedy:

  • 10mA maximum.


29
DIGIO 1 (T9) FAULT

Cause:
DIN3 overload on terminal 9.



Remedy:

  • 20mA maximum.


30
DIGIO 2 (T10) FAULT

Cause:
DOUT2 overload on terminal 10.



Remedy:

  • 50mA maximum.


31
UNKNOWN

Cause:
Unknown trip.



Remedy:

  • Consult technical support if persistent.


32
OTHER

Cause:
“OTHER” trip is active (Trip ID 34 to 44 inclusive).



Remedy:

  • Check specific Trip ID (34-44) for details.


34
MAX SPEED LOW

Cause:
During Autotune, MAX SPEED RPM limits the speed to less than the nameplate speed of the motor.



Remedy:

  • Increase the value of MAX SPEED RPM up to the nameplate rpm of the motor (as a minimum).

  • It may be reduced, if required, after the Autotune is complete.


35
MAIN VOLTS LOW

Cause:
The mains input voltage is not sufficient to carry out the Autotune.



Remedy:

  • Re-try when the mains has recovered.


36
NOT AT SPEED

Cause:
The motor was unable to reach the required speed to carry out the Autotune.



Remedy:

  • Motor shaft not free to turn.

  • The motor data is incorrect.


37
MAG CURRENT FAIL

Cause:
It was not possible to find a suitable value of magnetising current to achieve the required operating condition for the motor.



Remedy:

  • Check the motor data is correct, especially nameplate rpm and motor volts.

  • Check that the motor is correctly rated for the drive.


38
NEGATIVE SLIP F

Cause:
Autotune has calculated a negative slip frequency, which is not valid.



Remedy:

  • Nameplate rpm may have been set to a value higher than the base speed of the motor.

  • Check nameplate rpm, base frequency, and pole pairs are correct.


39
TR TOO LARGE

Cause:
The calculated value of rotor time constant is too large.



Remedy:

  • Check the value of nameplate rpm.


40
TR TOO SMALL

Cause:
The calculated value of rotor time constant is too small.



Remedy:

  • Check the value of nameplate rpm.


41
MAX RPM DATA ERR

Cause:
MAX SPEED RPM is set to a value outside the range for which Autotune has gathered data. The drive had no data for this new operating area.



Remedy:

  • To run the motor beyond this point it is necessary to re-autotune with MAX SPEED RPM set to a higher value.


42
LEAKGE L TIMEOUT

Cause:
The motor is moving during Autotune.



Remedy:

  • The motor must be stationary when starting the Autotune.


43
MOTOR TURNING ERR

Cause:
The motor cannot rotate during Autotune.



Remedy:

  • The motor must be able to rotate during Autotune.


44
MOTOR STALL ERR

Cause:
The leakage inductance measurement requires a test current to be inserted into the motor. It has not been possible to achieve the required level of current.



Remedy:

  • Check that the motor is wired correctly.


Product Code Error
Cause:
Internal product code error detected.



Remedy:

  • Switch unit off/on. If persistent, return unit to factory.


Calibration Data Error
Cause:
Internal calibration data error detected.



Remedy:

  • Switch unit off/on. If persistent, return unit to factory.


Configuration Data Error
Cause:
Internal configuration data error detected.



Remedy:

  • Press the E key to accept the default configuration.

  • If persistent, return unit to factory.
