8.2 Replacing an encoder

8.2 Replacing an encoder
Same interface, same encoder type
If you have to replace a defective encoder, then it is best if you use the same encoder type.
Same interface, different encoder type
If you use an different encoder type:
Different interface
If you connect the encoder at a different interface, you must perform a recommissioning.
8.2.1

Replacing the encoder - same encoder type

Procedure
Proceed as follows to replace a defective encoder by a new encoder of the same type:
1. Switch off the inverter power supply, including the external 24 V supply for the Control
Unit and digital outputs.
2. Replace the encoder. Connect the encoder cable shield as specified.
3. Switch on the power supplies.
4. If you have replaced an absolute encoder, and you use this encoder to sense positions,
then you must adjust the encoder. Further information about this topic is provided in the
"Basic positioner" function manual.
You have replaced the encoder.
