Replacing the Motor
• open main switch
• make sure main switch cannot be switched on again
• disconnect plug-in connectors
Note: When replacing the motor, cover the open mating sites of
power lines with protective caps if sprinkling with cooling
liquid/lubricant or soiling may occur (allowed degree of soiling
according to EN50178: 2).
• replace motor
Note: To mechanically replace the AC servo motor, observe the
instructions of the machine manufacturer.
• connect plug-in connectors
WARNING
Risk of accident due to accidental axis
movement.
⇒
Servo axes with indirect distance measuring system
via the motor encoder will loose the position data
reference when the motor is replaced!
This position data reference to the machine
coordinate system must therefore be reestablished
after replacement.
• for servo axes with absolute motor encoder, reestablish the position
data reference
