P0-19 UD
2nd position loop dierential time
constant
0 0 ~ 30000 ms P S T
◆
Set the position loop dierential time constant for position control.
◆
0 means no derivative eect, the smaller the set value, the stronger the eect of the derivative term. When the set value of the
dierential time constant (UD) is too large, the system's ability to suppress vibration is insucient, and obvious oscillation will occur
during the acceleration / deceleration process, the uniform speed process and after the stop, Oscillations will decrease gradually and
eventually stabilize.
◆
When the set value of the dierential time constant (UD) is reasonable, the system's ability to suppress vibration is signicantly
enhanced, and it tends to stabilize quickly.
◆
When the dierential time constant (UD) is set too small, the motion system will be too sensitive, easily vibrate and generate noise.

P0-20 UE 2nd position loop derivative lter 20000 0 ~ 40000 0.1Hz P S T
Set the position loop dierential low-pass lter for position control.
0 means no ltering eect. The dierential control parameters lter frequency. This lter is a simple one-pole, low-pass lter intended
for attenuating high frequency oscillations. This value is a constant that must be calculated from the desired roll o frequency.

P0-22 UP 2nd velocity loop gain 183 0 ~ 30000 0.1Hz P S T
Set the proportional gain of the speed loop. In order to improve the overall response of the servo system, it is necessary to increase
the speed loop gain value. Setting the value too high will cause vibration.

P0-23 UI
1st velocity loop integral time
constant
189 0 ~ 30000 ms P S T
Set the integral time constant of the speed loop.
0 means no integral eect, the smaller the set value, the stronger the integral eect.
This integral gain term is used to increase stiness and reduce steady-state velocity errors
