Mechanically replacing an encoder

This chapter describes how you mechanically replace the encoder.
Note
When replacing several encoders, always replace them individually and one after the other. In
this way you avoid interchanging components and descriptions.

retrofit a motor with another encoder type.
Precondition
You require:
• An encoder of the same type
• Suitable tool for Torx screws
• A workplace with sufficient space
• A fixture to fix the motor in a vertical position
