Setting Parameters
The function is enabled when you perform the operating procedure on page 8-59. To cancel
speed ripple compensation, use Pn423 = n.
0 (Disable speed ripple compensation) to dis-
able it.
If you enable speed ripple compensation, a compensation reference will be applied to reduce
ripple even when stopped at a 0 speed reference. In speed control mode, this may result in the
Servomotor moving slightly. To prevent this, set Pn423 = n.
