Current Control Mode Selection
Current control mode selection reduces high-frequency noise while the Servomotor is being
stopped.
The setting depends on the capacity of the SERVOPACK.
To use current control mode selection, use current control mode 2 (set Pn009 to n.1 or
n.2).

If current control mode 2 is selected, the load ratio may increase while the Servomotor is being
stopped.

Current Gain Level Setting
You can set the current gain level to reduce noise by adjusting the parameter for current control
inside the SERVOPACK according to the speed loop gain (Pn100). The noise level can be
reduced by decreasing the current gain level (Pn13D) from its default setting of 2,000% (dis-
abled). However, if the setting is decreased, the level of noise will be lowered, but the response
characteristic of the SERVOPACK will also be reduced. Adjust the current gain level within the
range that maintains the SERVOPACK response characteristic. This function is always disabled
during torque control (Pn000 = n.2).

If the current gain level is changed, the response characteristic of the speed loop will also
change. Servo tuning must therefore be performed again.
