CDE500 Vector Control AC Drive Chapter 6 Parameters Description
Figure 6- 36 PID feedback signal filtering
E5.09 Range: 0.0~999.9 Default: 100.0
PID proportional
gain Kp1
Unit: %
It decides the regulating intensity of the PID regulator.
100% indicates the adjustment amplitude of output frequency is
b0.00 (Max frequency) in PID regulator when the deviation between PID
feedback and PID setting is 100%.
0% means the PID regulator is a integral and differential controller.
Higher proportional gain can speed up the dynamic response.But too high
proportional gain will easily cause a system oscillation.
E5.10 Range: 0.01~99.99 Default: 1.00
PID integral time
Ti1
Unit: Sec
It decides the integral regulating intensity.The shorter the integral time is,
the larger the regulating intensity is.
1.00 second means the PID output will change with a speed of 10.0%/Sec
when the deviation between PID feedback and PID setting is 10%.
0.00 second means the PID regulator is a proportional and differential
controller.
The integral control can reduce the static error.
Short integral time can speed up the dynamic response.But too short
integral time will easily cause overshoot and system oscillation.
E5.11 Range: 0.000~9.999 Default: 0.000
PID differential
time Td1
Unit: Sec
It decides the regulating intensity of the PID regulator on the deviation
change. The longer the differential time is, the larger the regulating
intensity is.
1.000 second means the PID output will change 10.0% when the deviation
between PID feedback and PID setting is 10%.
0.000 second means the PID regulator is a proportional and integral
controller.
Differential control can forecast regulating intensity of the PID regulator on
the deviation change,then make a quick response to improve the system
dynamic performance.But it’s easily interfered.
