The address on completion of zeroing is the value automatically set in parameter No.42 (zeroing
position data).
(4) Adjustment
In dog type zeroing, adjust to ensure that the Z-phase signal is generated during dog detection. Locate
the rear end of the proximity 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".
