Motor Balance (OFFSET) Adjustment is used to adjust the GAIN for CW and CCW directions to be equal.
– Ex.1 in the figure shows that both the OFFSET and
GAIN are adjusted in both CW and CCW
directions.
– Ex.2 shows that the GAIN is adjusted but the
OFFSET is shifted. Therefore, the GAIN will be
big in CCW direction and small in CW direction.
As a result, motor becomes dull in CCW direction
and sensitive in CW direction causing problems.

Servo Motor
CPU
Servo Motor feeds back to the CPU the actual rotation corresponds to the instruction.
Motor tries to follow the instruction from the CPU.
Difference between the actual rotation and the
instruction could be adjusted with the Motor Balance
(GAIN) Adjustment.
– If the difference is small (=GAIN is small), motor
becomes very sensitive. As a result, it vibrates.
– If the difference is big (=GAIN is big), motor
becomes dull to the instruction. And as a result,
cutting quality will be damaged.
