Description Causes and Solutions
During Rescue Operation, either the DC bus voltage dropped below
DCVoltLvl@Rescue (A1) x (PS ReductnDetLvl (A1) - 10%), or 100 ms after
triggering Rescue Operation, the DC bus voltage did not reach
DCVoltLvl@Rescue (A1) x PS ReductnDetLvl (A1) before the motor started.
• Check the DC bus voltage setting for Rescue Operation.
• Lower the speed reference set for Rescue Operation.
• Check the backup power supply. It may need to be replaced with another
UPS if it has become worn and can no longer provide enough power.
Encoder cable is disconnected.
• Reconnect the cable.
Encoder cable wiring is wrong.
• Correct the wiring.
Encoder has no power.
• Check the power line to the encoder.
• Replace the encoder cable.
Motor brake is not released.
• Ensure the motor brake released properly.
Encoder hardware issue
• Verify encoder is operating, or replace the encoder.

• Check the DC bus voltage setting for DCVoltLvl@Rescue (A1).
• Lower the speed reference set for Rescue Operation.
• Check the backup power supply. It may need to be replaced with another

Encoder cable is disconnected.
• Reconnect the cable.
Encoder hardware issues.
• Verify the encoder is operating, or replace the encoder.
PG option card is having issues.
• Verify that the correct PG encoder card is connected, and it is in the CN5-C
slot.
The proper braking resistor option has not been installed.
• Select the braking resistor option so that fits to the drives braking transistor
specification.
A regenerative converter, regenerative unit or braking unit is being used and
the +1 or +3 terminal is connected to - terminal.
• Disable the DB Tr Protection (C1).
The braking transistor is damaged, or the control circuit is damaged.
• Cycle power to the drive and check if the fault reoccurs.
• Replace either the control board or the entire drive. For instructions on
replacing the control board, contact Magnetek.
IGBT Fault, or IGBT short circuit detection circuit fault.
• Check the wiring to the motor.
• Turn the power supply off and then on again to check operation.
• If the problem continues, contact Magnetek.
The drive is damaged.
• Check the drive output side short circuit for broken output transistor from:
B1 and U/V/W and - (negative) and U/V/W.
A digital input set to (MEMOBUS/Modbus test) was closed while the drive
was running.
• Stop the drive and run the test again.
There is a problem with the motor contactor or auxiliary switch.
• Check the motor contactor, auxiliary switches and the wiring of the
contactor feedback signal.
The motor contactor is open.
• Check the contactor for any problems.
• Check for any sequencing problems between contact picking and the drive
being told to run.
