The motion detected by the proximity dog slows down to stop, and return to the proximity dog front end,
setting there to the home position. When deviation compensation is invalid, only the proximity dog signal
for the master axis is used.

Note 1. The proximity dog signal for the master is the only valid signal. The slave axis also returns to home position based on the
proximity dog signal for the master.
2. The final stop position for both the master axis and the slave axis is based on the master axis proximity dog front end. Also,
only the master axis parameter for the value for the home position shift amount is valid.
