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 automatic 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. The home-return complete signal HEND is kept ON
unless the memory of origin point is lost for a reason. The positioning complete signal PEND
turns OFF and the moving signal MOVE turns ON during a home-return operation.
