Replacing Motor
NOTE: Perform the work only when the material is soft (approx. 70°C /
158°F, depending on material); otherwise the coupling can not be turned.
1. Disconnect motor power cable in the electrical cabinet.
2. Detach plug connector from motor controller.
3. Turn the coupling until the screws of the coupling half shells are
accessible.
4. Release the screws of the coupling half shells on the motor side.
5. Remove the coupling half shell carefully from the motor side to prevent
the coupling from falling apart.
CAUTION: The bracket should not be slid back in the slot or unscrewed. If
this is unavoidable, refer to Aligning Motor.
6. Unscrew motor from bracket (1).
7. Remove any protective varnish from the shaft of the new motor.
8. Attach the coupling to the shaft without using force (no jolts or pounding).
If necessary, sand pulley keys and shaft with emery cloth. Lubricate
pulley keys and shaft if needed.
9. Install the new motor in the bracket. Tighten the fixing screws crosswise
using a torque wrench. Torque: 20 Nm / 177 lbin.
10. Attach coupling (Refer to Important Regarding Coupling). Torque
(screws): 36 Nm / 320 lbin.
Reconnect motor electrically.
11. Secure power cable with strain relief. Ensure that the cable shield and the
clamp have contact.
12. Verify that the connection effects the desired direction of rotation (see
arrow).
