4-5-25 Limit signal of homing, Trigger signal of zero-return

These functions are used for homing performance.
One of three types of homing operations can be selected by homing mode
P068
selection ( ). When a homing operation ends, the current position counter
is cleared (to 0). Use homing direction selection (
of homing operation. If homing operation is not performed, position control is
performed based on the assumption that the motor position detected at
power-on is the origin.
