Adjustments
5.8.3 Current Control Mode Selection Function
This function reduces high-frequency noises while the servomotor is being stopped. This function is enabled
by default and set to be effective under different application conditions. Set Pn009.1 = 1 to use this function.
This function can be used with the following SERVOPACKs.
5.8.4 Current Gain Level Setting
This function reduces noises by adjusting the parameter value for current control inside the SERVOPACK
according to the speed loop gain (Pn100). The noise level can be reduced by reducing the current gain level
(Pn13D) from its factory setting of 2000% (disabled). If the set value of Pn13D is decreased, the level of noise
will be lowered, but the response characteristics of the SERVOPACK will also be degraded. Adjust the current
gain level within the allowable range at which SERVOPACK response characteristics can be secured.
5.8.5 Speed Detection Method Selection
The speed detection method selection can be used to smooth the speed of the servomotor during operation. To
smooth the speed of the servomotor during operation, set Pn009 to n.1 to select speed detection 2.

Selects the current control mode 2 (low noise).
• If current control mode 2 is selected, the load ratio may increase while the servomotor
is being stopped.
