Note 1. External input signal detection delays by the input filter setting time of parameter No. PD19. Additionally, make up a
sequence that changes DI0, DI1 and DI2 ahead of time by considering delays in output signal sequence from the controller
and variations of a signal change due to hardware.
2. Point table method: Select the home position return mode by turning OFF DI0, DI1 and DI2.
Program method: Select a program that has the home position return "ZRT" command.
The set value in parameter No. PE08 (home position return position data) is applied as position address at the
time of the home position return being completed.
