• Use this parameter to determine speed loop responsiveness.
• The setting for the Speed Loop Gain must be increased to increase the Position Loop Gain and
• The setting unit for Pn11 will be Hz if the Inertia Ratio (Pn20) is set correctly.
• Use this parameter to set the speed loop integration time constant.
• The smaller the setting, the faster the deviation will come close to 0 when stopping. If 1000 is set,
improve the responsiveness of the entire servo system. Setting the Speed Loop Gain too high,
however, may result in oscillation.
the integral will be ineffective.
Speed Loop Gain
Speed Loop Integration Time Constant
When the speed loop gain is changed, the response is as shown in the following diagram.
When the speed loop integration time constant is changed, the response is as shown in the fol-
lowing diagram.
