Note. Configure a sequence that changes the point table selection earlier, considering the delay time of CC-Link communication.
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.
