5.2.7 PG Offset Value Adjustment
 Overview
To compensate the deviation of the PG position (see Table5.3.1 (p235)) derived from
the difference of the result of PG Adjustment (p235) due to individual variability of the
mechanism, write the notch positions of the parallelism adjustment bushings when PG
Adjustment (p235) is performed into EEPROM to correct the PG position during APG
operation.
 Preparation
After PG Adjustment (p235) is complete, check the notch position of the parallelism
adjustment bushing at the rear on the 0-column side and note down the offset value
according to the figure below.
