– You can remove the encoder directly by inserting a special screw (see diagram).
– If a special screw is not available, you can remove the encoder by inserting a threaded
pin (e.g. DIN 913 M5 x 30) into the end of the motor shaft to protect the centering hole
thread and then inserting a screw M6 x min. 40.
