Parameters Details
 Determine 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 too high, however, may result in
vibration.
 The setting unit for Pn101 is Hz if the Inertia Ratio (Pn004) is set correctly.
When the speed loop gain is changed, the response is as shown in the following diagram.
 Set the speed loop integration time constant.
 The smaller the set value, the faster the error comes close to 0 when stopping. Set to 9,999 to
maintain integration. Set to 10,000 to invalidate the effect of integration.
When the speed loop integral time constant is changed, the response is as shown in the
following diagram.
 Set the time constant for the low pass filter (LPF) after speed detection to one of 6 levels (0 to 5).
 Increasing the set value increases the time constant and decreases the noise generated by the
motor. Responsiveness, however, also decreases.
 Normally, use the default set value.
