Monitoring Over/undervoltage, temperature of the motor and the
output stage
1) Forces for a bearing life of 20000 h
2) The idling speed indicates the max. possible speed of the drive system under
no−load condition depending on the supply voltage of the inverter.
3) Maximum torque at a speed of 0 min −1 to 500 min −1
4) Maximum torque at rated speed
5) The information refers to the torque indicated on the motor shaft. In these values,
the friction torque of the motor is also considered!
