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. During the home return operation,

positioning completion signal PEND and moving signal MOVE are set to OFF and ON,

respectively.
