The setting value of [Pr. PT08 Home position return position data] and [Pr. PT58 Home position return
position data (extension parameter)] is used as the position address at the homing completion.
(4) Adjustment
For the dog type homing, adjust the Z-phase so that the Z-phase signal is surely generated while
detecting a dog. Make an adjustment so that the rear end of DOG (Proximity dog) is positioned almost at
the center between the positions specified by a Z-phase signal and the next Z-phase signal.
The generated position of the Z-phase signal can be checked with "Position within one-revolution" of
"Status Display" on MR Configurator2.
