If you use the motor table motor.sn instead of motor.mot, the control
attempts to communicate with an encoder with EnDat interface. The control
then assumes that it is dealing with an encoder with a Z1 track, and tries to
read the track. If this is not possible, for example because it is actually an
encoder with EnDat interface, the error message C3F0 DSP error in axis
<axis> appears.
