Description:
Runtime error if at least one of the six transistors in the inverter or the transistor for the braking resistor registers overcurrent.
When using the following ACOPOS servo drives, this error is also registered for overcurrent in the current transformer (U and V):
8V1180.xx-x....95.4 Apeak
8V1320.xx-x....160.4 Apeak
8V1640.xx-x....400.0 Apeak
8V128M.xx-x....585.0 Apeak
Reaction:
Synchronous motor: Movement stop with short-circuit braking.
Asynchronous motor: Movement stop by switching off the power section and switching on the holding brake.
If the error occurs two times consecutively, then a movement is stopped by switching off the power section and switching on the holding brake.
Setting STOP_ERR_DECEL_RAMP=ncCTRL_OFF:
Movement is aborted by switching off the controller and the power section immediately. The drive has no electrical torque.
Cause/Remedy:
Motor wiring error:
- Phase and ground conductor switched. -> Check if the ground conductor PE in the motor cable on the X5 plug is connected with motor phase U, V or W.
- Short circuit in the motor cable. Short circuit between two phases, ground PE and phase or shield and phase. -> Check the resistance between U-V, V-W, W-U, U-PE, V-PE, W-PE, U-shield, V-shield and W-shield.
Motor defect:
- Winding short in a motor phase. -> Check on the motor plug and on the motor terminals if two of the three motor impedances (phase-phase) have lowered.
- Winding short between two motor phases. -> Check on the motor plug and on the motor terminals if one of the three motor impedances (phase-phase) has lowered.
- Housing short between motor phase and housing. -> Using a continuity tester or a megohmmeter, check the insulation resistance between the motor phases and the housing.
ACOPOS servo drive defect:
See error number 6052.
See error number 6054.
- Alloyed transistor or control for braking resistor defective. -> Check if the error is registered when the DC bus voltage UDC_ACT is greater than the switch-on voltage of the braking resistor UDC_BLEEDER_ON.
External braking resistor defect:
- Short circuit. -> Check if the error is also registered when the external braking resistor is not connected.
Set current value jump: See error number 9300. This cause is more likely on devices with current transformer monitoring.
