8.11.3 Setting Parameters

The function is enabled when you perform the operating procedure on Operating Procedure on
page 8-61. To cancel speed ripple compensation, use Pn423 = n.0 (Disable speed ripple
compensation) to disable it.
Pn423
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
motor moving slightly. To prevent this, set Pn423 = n.X (Speed Ripple Compensation
Enable Condition Selection) and Pn427 or Pn49F (Speed Ripple Compensation Enable Speed).
Pn423
• For Rotary Servomotors
Pn427
• For Linear Servomotors
