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
Replacing the Supply Unit
Note: Replacing the unit requires, depending upon unit weight, a
lifting device and an identical replacement unit.
DANGER
Electrical shock due to voltage-containing parts
of more than 50 V!
The unit may only be replaced by qualified
personnel, which have been trained to perform the
work on or with electrical devices.
Note: Prior to the replacement of the unit please check according to
the type plates, whether these units are of the same types.
Replace only units of the same types.
Proceed as follows:
1. Switch voltage to installation off and secure it against being switched
back on.
2. Using an appropriate measuring device, check whether the
installation is power free. Wait the discharge time.
3. Motors must be standing still.
4. Secure vertical axes against motion.
5. Release all connections from the defective unit.
6. Release the fixing bolts and remove the unit from the control cabinet.
Use the lifting device, if necessary.
7. Hang replacement unit into mounting rails. Use the lifting device, if
necessary.
