Cause | Measure | |
A fault occurred in a hardware component of the power section, e.g.: Overcurrent hardware comparator. | – Check the current supply. – Increase the ramp time. – Check for correct motor size (the motor current is too high). – Contact SEW-EURODRIVE Service. | |
Switched-mode power supply fault, hardware fault. | – Check the current supply. – Check the DC 24 V supply voltage. | |
Fault at the gate driver of an IGBT. | Defect in the power output stage. Contact SEW‑EURODRIVE Service. | |
