Fault 1 Output stage monitoring
Fault: 1.1 (0101hex | 257dec) Description: Overcurrent on motor output terminals | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
Short circuit at the motor output. | – Check motor cable for short circuit. – Remove the short circuit. | |
Power output stage defective. | Contact SEW-EURODRIVE Service. | |
Motor current too high. | Connect a smaller motor. | |
Fault: 1.2 (0102hex | 258dec) Description: Overcurrent in output stage | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
Motor current too high. | Connect a smaller motor. | |
Current controller of intelligent supply module set incorrectly. | Contact SEW-EURODRIVE Service. | |
Ramp time too short. | Increase the ramp time. | |
One of the following components is faulty: – Internal current supply – Current measurement – Phase module | Contact SEW-EURODRIVE Service. | |
External DC 24 V supply voltage instable. | Check the DC 24 V supply voltage. | |
The voltage fluctuations are too strong. The current controller of the intelligent power supply module cannot compensate for them. | – Stabilize the voltage. – Check the supply. – Check the project planning. | |
