3.1 Features
The 931M servo inverter is a synchronous motor with integrated busable servo inverter.
The difference between the 931W and the 931M servo inverters is the separate design of
motor and servo inverter.
Type M and W have the same functionalities in both voltage variants 230 V AC/320 VDC
and 24/42 V DC.

The servo inverters are equipped with different monitoring functions such as over and
undervoltage monitoring, following error monitoring, temperature monitoring, etc.. Both
motor or winding temperature and the temperature of the power electronics of the drive
controllers are detected. Due to the temperature sensitivity of the power electronics, a
power derating will be carried out from inverter temperatures of 70°C onwards. With
inverter temperatures of 78°C or more, the servo inverters will be switched off.
Only synchronous motors with resolver will be used as motors. The technical data of the
individual versions are listed in the following tables.
