Offset Input for CR
Motor Calorific
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.
Selecting this function saves the offset into the EEPROM. Non-target
