Note1: Pattern 5 cannot make a home return with HOME signal. Refer to 3.8.4 [1] Home
Return (ST0, HEND) for how to perform a home-return operation.
The HOME signal is intended for home return. The HOME signal is caught at the rising edge
(ON edge) to start the home return. At completion of the home return, home return completion
signal HEND is turned ON. Home-Return Complete Signal HEND will be kept ON once it is
turned ON even if getting off the home position. (HEND turns OFF when home position is lost
and undetermined.) Even when HEND is ON, home-return operation can be conducted again
by turning HOME Signal ON. HEND should be OFF during the home-return operation and
should be turned ON again once the home-return operation is complete.
Also, the positioning complete signal PEND turns OFF and the moving signal MOVE turns ON
during a home-return operation.
