How did you confirm the encoder is working?
I assume this is the DC brushed motor version? If so there should be no encoder re-alignment?
The extra set of wires could be a Tach?
On many systems, the display shows anticipated position, not the actual position, some like Fagor have the option by parameter to set either case.
If your machine is the former, then you cannot check the encoder this way.
I have done it by disconnecting the motor power leads, and use a H.W. to increment a distance lower than the following error, then turn the motor by hand the same distance represented by the ball screw etc, if the H.W. is incremented and the manual turns to keep up with the anticipated display are done, if the encoder is OK, there will be no following error.
Sounds a bit complicated but it works.
