Motor
• Check the servo motor for any transport damage. Never install a servo motor that
shows clear signs of damage!
• Ensure that any anti-corrosion agents and/or contamination on the shaft end (drive
end) are thoroughly removed. This can be done using a standard solvent. Make sure
that the solvent cannot come into contact with the gaskets and/or bearings, otherwise
materials may be damaged!
Carrying out the installation
WARNING!
Electric shock
Contact with live parts will result in serious injury.
The motor should always be installed with the supply voltage switched off. Switch off
the supply voltages to all connected devices!
Hazardous values may still be present up to 5 minutes after the voltage is switched off,
due to residual charges in the servo amplifier’s capacitors.
When the shaft is rotating (externally driven, running down) the motor acts as a
generator. This means that hazardous voltages will be present at the connection
terminals.
If possible, only use backlash-free, frictionally engaged chucks or clutches.
Use the tightening thread provided in the motor shaft to tighten the clutches, gears or
belt pulleys and, if possible, warm up the drive elements. Do not use excessive force as
this will damage bearings, feedback and the motor shaft.

Please note:
• Align the clutch correctly
Misalignment can cause undue vibration and can damage the ball bearings and
clutch!
