Replacing the Motor

Replacing Cables

• Switch main switch off.
• Make sure main switch cannot be switched on again.
• Disconnect plug-in connectors.
Note: When replacing the motor, cap open connector ends
particularly if there might be the chance that they get in contact
with coolant/lubricant or dirt (allowed level of contamination is
V2 according to DIN VDE 0160).
• Replace motor.
Note: To mechanically replace the AC servo motor, note the
instructions of the machine manufacturer.
• Connect plug-in connectors.
Danger caused by unwanted axis motion!
⇒ Servo axes with indirect path measuring system via
the motor encoder will loose the reference dimension
when the motor is replaced!
ATTENTION
This reference to the machine coordinate system
must therefore be reestablished after replacement.
• Servo axes with absolute motor encoder: reestablish the reference
dimension.
Lethal electric shock caused by live parts with
more than 50 V!
⇒ Power connectors of the cables may only be
separated or connected if the installation has been
ATTENTION
de-energized!
Note: When replacing cables, note the instructions of the machine
manufacturer.
If you do not use standard cables from Rexroth, then check to
ensure that the cables agree with the terminal diagram of the
machine manufacturer!
• Switch main switch off.
• Make sure main switch cannot be switched on again.
• Disconnect plug-in connectors.
