Description Causes and Solutions
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.
The feedback contact on the brake is defective or the wiring is incorrect.
• Check the brake feedback contact and the wiring.
The brake control circuit does not work properly.
• Ensure the motor brake operates properly with a brake control command
from the drive.
Torque Limit is set too low.
• Set the torque limit to an appropriate value using Mtr Torque Limit (A1)
and Regen Torq Limit (A1).
Excessive load torque.
• Reduce the amount of load torque.
Noise interference along encoder wiring.
• Check the encoder signal for noise reference.
The wrong motor code has been set (only used for motor by drive
manufacturer).
• Enter the correct motor code for the PM being used into the A5 sub-menu.
• For special-purpose motors, enter the correct data to all parameters in the
A5 sub-menu according to the Test Report provided for the motor.
Load is too heavy.
• Reduce the load.
• Increase the motor or drive capacity.
Accel/decel ramp is too short.
• Lower the acceleration and deceleration in the A2 sub-menu.
• Lower the jerk setting in the A2 sub-menu.
IGBTs have reached 90% of their expected performance life.
• Replace the drive.
Parameter settings are not appropriate for the load.
• Check the settings of parameters.
There is a fault on the machine side.
• Check the load for any problems.
Parameter settings are not appropriate for the load.
• Check the settings of parameters.
There is a fault on the machine side.
• Check the load for any problems.
