Adjustments
6.8.3 Current Control Mode Selection
This function reduces high-frequency noises while the motor is being stopped. This function is enabled by
default and set to be effective under different application conditions.
6.8.4 Current Gain Level Setting
This function reduces noises by adjusting the parameter value for current control inside the SERVOPACK in
accordance with the parameter value for the speed loop gain (Pn100). To change the parameter value for cur-
rent control, the current gain level must be changed from 2000%, which is the default value of Pn13D to dis-
able this function. This function is always disabled in torque control mode (Pn000.1 = 2).
Note: If the set value of Pn13D is decreased, the level of noise will be lowered, but the responsiveness of the SERVO-
PACK will also be degraded. Lower the current gain level to one at which SERVOPACK responsiveness can be
secured.
6.8.5 Speed Detection Method Selection
This function can ensure smooth movement of the motor while the motor is running. This function is disabled
by default. Set the value of Pn009.2 = 1 to enable this function.

• If the parameter setting of the current gain level is changed, the responsiveness char-
acteristic of the speed loop will also change. The servo must, therefore, be readjusted
again.
