band compensation
(4) Fine torque compensation
There may be cases when not much torque is generated during low speed feed, or when the wear
torque and unbalance torque during lowering an unbalance axis or the wear torque and
deceleration torque before a quadrant torque changeover during circular cutting are unbalanced.
These can cause the motor output torque to be approximately zero and the control accuracy to
drop. In this case, the control accuracy can be improved by using fine torque compensation. Note
that this may cause vibration during motor operation to increase.

Chapter 8 Adjustment
Set the standard value 20. Note that the vibration could increase during
motor operation.
Set the fine torque compensation amount Cx in the high-order
8 bits.
Normally, 0 is set. Set 255 to use this function.
µm Set the fine torque compensation Cy in the high-order 8 bits.
Normally, 0 is set. Set 255 to use this function.
