7-2 Gain Parameters

*1 The default setting is 180 for a Servo Drive with 200 V and 1 kW or more.
This parameter determines speed loop responsiveness.
The setting for the speed loop gain must be increased to increase the position loop gain and improve
the responsiveness of the entire servo system. Setting it too high, however, may result in vibration.
The setting unit for Pn101 is Hz when Inertia Ratio 1 (Pn004) is set correctly.
Response for Speed Loop Gain Changes
*1 The default setting is 310 for a Servo Drive with 200 V and 1 kW or more.
Set the speed loop integral time constant.
The smaller the set value, the faster the error approaches 0 when stopping. When set to 9,999, the
effect of integration will be held. However, it will be lost when set to 10,000.
Response for Speed Loop Integral Time Constant
Set the time constant for the low pass filter (LPF) after speed detection in six levels (0 to 5).
Increasing the set value increases the time constant and decreases the noise generated by the
Servomotor. Responsiveness, however, also decreases.
Normally, use the default set value.
