Home return signal HOME is a signal for performing home return motion.
When the HOME signal is turned ON, home return motion starts as the signal starts up (ON
edge). When the home return motion is completed, the home return complete signal HEND
turns ON. The HEND signal will stay ON unless the home is lost. During home return motion,
the positioning complete signal PEND turns OFF and the moving signal MOVE turns ON.
Caution
● In the positioner mode and simple direct mode, when an actuator with incremental
specification is connected and the positioning command is made to the position without
performing home return at power on, positioning is executed after home position is
automatically restored after the power is turned on (first time only).
● Note that in the direct numerical control mode, when a positioning command to the
position is made without executing home return at power-on, alarm code 083 "Absolute
position travel command in home return uncompleted status" is generated and
operation is canceled.
