Details
:
This parameter is used to set the second speed loop proportional gain, customers can switch it from the first speed loop
proportional gain, please refer to chapter 5 section 5.8 for gain switching function.
The larger the value is, the greater the stiffness would be. The value is determined by the type of servo and the load condition. In
general, larger load inertia needs larger value. If there is no oscillation, the higher the value is the better the servo system performs.
Note
:
For different motor, the default value is different.

The smaller the value, the greater the stiffness. The value is determined by the type of servo and the load condition. In general, larger
load inertia needs larger value. Set the parameter as small as possible without oscillation.
Note
:
For different motor, the default value is different.
Pn-38
Parameter
The second low-pass bandwidth of speed loop
(

This parameter is used to set the second low-pass bandwidth of speed loop, customers can switch it from the first speed loop
proportional gain, please refer to chapter 5 section 5.8 for gain switching function.
Normally, smaller value results in slower and smoother speed response. Too small value may cause system oscillation.
