6.8.3 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.

6.8.4 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. This
function is always disabled in torque control (Pn000.1 = 2).

6.8.5 Speed Detection Method Selection

This function can ensure smooth movement of the servomotor while the servomotor is running. Set the value
of Pn009.2 to 1 and select speed detection 2 to smooth the movement of the servomotor while the servomotor
is running.

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.

• If the parameter setting of the current gain level is changed, the responses character-
istics of the speed loop will also change. The SERVOPACK must, therefore, be read-
justed again.

Selects speed detection 2.
• If the speed detection method is changed, the response characteristics of the speed
loop will change and the SERVOPACK must be readjusted again.
