|---|---|---|
| Response: Output stage inhibit + line contactor unchanged + module bus response "Critical" | |
Cause | Measure | |
Motor current too high. | Connect a smaller motor. | |
Current supply | Check the current supply. | |
Current transformer | Check the current transformer. | |
Ramp limit deactivated and set ramp time too short. | Increase the ramp time. | |
Phase module defective. | Check the phase module. | |
