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 such as alarm. During the home return
operation, positioning completion signal PEND and moving signal MOVE are set to OFF and
ON, respectively.
