Origin Compensation
The encoder phase Z position may not always designate the mechanical ori-
gin as desired. Sometimes the origin may be preferred a few pulses CW or
CCW from the phase Z pulse. In order to correct the origin’s position, set the
origin compensation parameter (addresses 414 for the X axis and 814 for the
Y axis) with the amount of compensation desired. Once the parameter is set,
the origin is established according to the desired compensation from the
phase Z pulse detected during origin search.
