Commissioning
7.3 Putting the motor into operation
Only put the synchronous servo motor into operation if you have reviewed its installation
and connection in accordance with this documentation as well as all other necessary re-
quirements specific to your system. In addition, follow the instructions for commissioning
your servo amplifier. In multi-unit systems, every drive must be put into operation individu-
ally.
7.3.1 Notes for troubleshooting
The following table includes typical faults that can occur on the synchronous servo motor
during commissioning. Other possible fault sources include the corresponding servo ampli-
fier, any higher-level controller or the integration of the motor into a multi-unit system.
Therefore, observe the respective documentation.

– Observe the specifications in this operating manual and in the docu-
mentation of the servo amplifier used.
– Make sure that components attached to the motor, such as feather
keys and coupling elements, are sufficiently secured against centrifu-
gal forces.
