5. Spindle Adjustment
5 - 34
(8) Adjusting excitation rate
If the motor noise is excessive during constant-speed operation, adjust the variable excitation
(SP056) value downward in decrements of 10 from the standard setting of 50 (setting lower limit =
25). The SP033/bit9 parameter setting is an effective way to reduce noise for high-speed operation
only (it lowers the excitation rate for high-speed operation only).

(min value)
Set the minimum value of the variable excitation rate.
Select a smaller value when gear noise is too high.
Larger value is more effective on impact response.
