8.1 Maintenance
With proper installation, the synchronous servo motors are largely maintenance-free. Since
operating conditions vary greatly, maintenance intervals must be adapted to the local condi-
tions (e.g. pollution degree, activation frequency, load).
Maintenance – Regular
Cleaning the synchronous servo motor
}
The cleaning intervals depend on the local pollution degree; note that the original finish
must be preserved. Let the motor cool before cleaning; do not use solvents; select the
individual cleaning methods based on the protection class of the motor.

DANGER!
Electric shock!
Serious injuries due to contact with live parts!
– Carry out all work on a de-energized motor!
– Make sure that the motor shaft is stationary during all work. A rotat-
ing rotor can cause high voltages at the connections.
– Disconnect the supply voltage. Be aware that there may still be dan-
gerously high voltages at the servo amplifier, even 10 minutes after
switching off the supply voltage, due to the residual charge of the link
capacitors.
– Cover all open electrical connections, e.g. using protective caps.
– Secure the installation location as per regulations, e.g. using locks or
warning signs.
NOTICE
Be aware that synchronous servo motors may be repaired only by Pilz
GmbH & Co. KG. Unauthorized opening of a synchronous servo motor and
improper handling will void the warranty.
