Fault 1 Output stage monitoring

Error: 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.

Error: 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 power 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.

Error: 1.5 (0105hex \| 261dec) Description: Unexpected shutdown
	Response: Output stage inhibit
Cause	Measure
The output stage has been inhibited. The precise cause of the fault could not be determined.	– Acknowledge the fault. – If the fault occurs repeatedly, contact SEW‑EURODRIVE Service.
