Faults to be reset
The cause of the fault should be rectified before resetting by powering down until the display goes out, then
switching on again.
Fault Probable cause Remedy
/92
CANopen fault
• CANopen bus communication
interrupted
• Check the communication bus.
• Please refer to the product-specific
documentation.
/H2
capacitor load circuit
• Load relay control fault or charging
resistor damaged
• Replace the drive.
112
EEPROM fault
• internal memory fault • Check the environment
(electromagnetic compatibility).
• Replace the drive.
5D2
internal fault
• Short-circuit on 10 V supply
• Internal fault
• Check the circuits connected to the 10 V.
• Check the wiring of inputs AI1 and AI2
and the RJ45 connection.
• Check the environment
(electromagnetic compatibility).
• Replace the drive.
722
Loss of 4-20mA
• Loss of the 4-20 mA reference on input
AI3
• Check the connection on input AI3.
9>2
overvoltage
during deceleration
• Braking too sudden
• Driving load
• Increase the deceleration time.
• Install a braking resistor if necessary.
• See the brA function (please refer to the
CD-ROM).
9/2
overcurrent
• Incorrect parameters in the SEt- and
drC- menus
• Inertia or load too high
• Mechanical locking
• Check the SEt- and drC- parameters.
• Check the size of the motor/drive/load.
• Check the state of the mechanism.
942
drive overload
• Drive temperature too high • Check the motor load, the drive
ventilation and the environment. Wait
for the drive to cool down before
restarting.
972
motor overload
• Triggered by excessive motor current
• Incorrect value for parameter rSC
• Check the ItH setting (motor thermal
protection) (page 31), check the motor
load. Wait for the drive to cool down
before restarting.
• Re-measure rSC (see page 33).
9:2
motor phase break
• Loss of phase at drive output
• Downstream contactor open
• Motor not connected or motor power
too low
• Instantaneous instability in the motor
current
• Check the connections from the drive to
the motor.
• If a downstream contactor is being
used, set OPL to OAC (please refer to
the CD-ROM, FLt- menu).
• Test on a low power motor or without a
motor: set OPL to nO (please refer to
the CD-ROM, FLt- menu).
• Check and optimise the UFr (page 31),
UnS and nCr (page 33) parameters and
perform auto-tuning with tUn (page 34).
9;2
overvoltage
• Line voltage too high
• Disturbed line supply
• Check the line voltage.
