WARNING!
Electric shock hazard!
Risk of serious injury from contact with live parts!
 Observe the 5 safety rules (see chapter 2.5 Working on the machine).
 Disconnect the motor from the power supply before carrying out work!
 Ensure that the motor shaft is at a standstill before carrying out work! A rotating rotor
can generate high voltages at the terminals.
 Switch off the power supplies to all connected devices and devices to be connected.
Note that dangerously high voltages can still occur at the servo amplifier even 10
minutes after switching off the power supply due to the residual charge of the DC link
capacitors.
 Cover all open electrical connections, e.g with protective caps.
 Cordon off the installation area according to the safety regulations, e.g. with barriers,
warning signs.
8.1 Maintenance
If properly installed, the servo motors are more or less maintenance-free. As the operat-
ing conditions can differ widely, the maintenance intervals must be adapted to the condi-
tions at the operating site (e.g. degree of soiling, cyclic duration factor, load).
INFO
Note that repairs must only be carried out by Pilz GmbH & Co. KG. If the ser-
vo motor is opened without authorisation and handled improperly, the war-
ranty will be rendered invalid.
Maintenance interval What is to be done? What has to be observed?

inal paintwork must be retained at all
costs:
•
Allow the motor to cool down
• Do not use solvents
• Select the cleaning method accord-
ing to the protection class of the ser-
vo motor
