8.4.2 Procedure for Parameter Adjustment
1.Velocity Loop Adjustment
(1) Adjust Kvp according to the load.
① Set motor running at Auto Reverse mode by position(Operation mode -3),then open oscilloscope and set
the parameters to observe the curve.As shown in following figures.
② Adjust Kvp and observe the speed curve.Following figures show the different curve in different
Kvp.According to the curve,it shows that the bigger value of Kvp,the faster response of speed.
(2) Adjust Kvi according to load.
(3) Adjust Speed_Fb_N to reduce system noise.
Speed_Fb_N:This parameter is used to reduce system noise.But the bigger value of this parameter,the
slower response of system.
In Auto Reverse mode,Kvp=40
The oscilloscope is shown as follows:actual speed response is 33.88ms
