Limitation
When the Main Board, CR Motor or PSB/PSE Board is changed
individually, this adjustment is made to write the maximum
offset to prevent the occurrence of damage to the motor at the
time of CR Motor heat generation.
However, when the CR Guide Shaft is changed together with
the above part, this adjustment is made to measure the
manufacturing variations of the CR Motor and PSB/PSE Board,
utilize the motor capability to the maximum for motor heat
generation control, and prevent the motor from being damaged
by CR Motor heat generation.
Select and execute this function in the exclusive servicing program to
save the offset into the EEPROM.
