Safety
- Drive/power/encoder circuit: hazardous voltages may remain in the DC link after power-off. Lock out / tag out, wait for discharge per the drive documentation, and use qualified personnel only.
Common Causes
- The matching factor from setpoint torque to cross current in the speed controller is too large
Troubleshooting Steps
- 1Please inform the authorized personnel/service department.
- 2For standard motors: Reset the drive (delete the bootfile) and repeat the startup.
- 3For third-party motors: Check and, if necessary, refer to the motor data sheet to correct MD 1103: $MD_MOTOR_NOMINAL_CURRENT (rated motor current) or MD 1107: $MD_INVERTER_MAX_CURRENT (transistor limit current) or MD 1113: $MD_TORQUE_CURRENT_RATIO (torque constant).
- 4Switch control OFF - ON. 2-729
