Note. External input signal detection delays by the input filter setting time of parameter No. PD19. Also, make up a sequence that will
change the point table selection earlier by the time that takes into account the output signal sequence from the controller and the
variation of a signal change due to the hardware.
The parameter No.PC07 (home position return position data) setting value is the positioning address after
the home position return is completed.
(4) Adjustment
In dog type home position return, adjust to ensure that the Z-phase signal is generated during dog
detection. Locate the rear end of the proximity dog (DOG) at approximately the center of two consecutive Z-
phase signals.
The position where the Z-phase signal is generated can be monitored in "Within one-revolution position" of
"Status display" of the MR Configurator or the parameter unit.
