5 Inspection/Maintenance
Isolate the drive from the supply before you start any maintenance work and safeguard the
drive against unintentional power-up. Do not undo connectors while the drive is energized.
Only use original spare parts in accordance with the valid parts list.
5.1 Inspection and maintenance periods
The service life of a part is influenced by many factors and differs for the various parts. Inspection
and maintenance periods must therefore be determined individually in accordance with the project
planning documentation. Carry out regular visual inspections of the drive.
The bearings should only be changed by SEW-trained personnel since the resolver must be re-set
each time the motor has been disassembled.
