Further information

The thermal motor protection without temperature sensor is active as long as the inverter is in operation and supplied with at least DC 24 V.

The thermal motor protection without temperature sensor has no memory, i.e. it does not take the current motor temperature into account after a switch-on/switch-off process. Consequently, avoid subjecting an overheated motor to another overload immediately by switching the inverter off and on. SEW-EURODRIVE recommends performing a fault reset in the event of a fault message of the thermal motor protection without temperature sensor, instead of switching on or off.
