V
It defines low-speed loop switching frequency, the parameter and switching frequency at
high-speed optimize Speed-loop PID parameter.
C05
Speed loop high speed Ti
0.01~100.00
s
0.50
Y
It defines integration time of High-speed section of the speed loop.Range is
0.01~100.00s.integration time too large and unresponsive, external interference control variation
becomes weak ; integration time is small the reaction speed, oscillation occurs when it is too small
C06
Speed loop high speed Td
0.000~1.000
s
0.000
Y
It defines the differential time of the speed-loop high speed segment and the range is
0.000~1.000s.
If the time is great enough, the surge which is caused by P action when difference occurring
can attenuate quickly. But too great, the surge will happen contrary. When the time is little, the
attenuation function is little too.
C07

Y
It defines the proportion gain of speed loop high-speed section, range from 0~1000%. Gain
is large,response speed, but too large gain will occur vibration; if the gain is small, the reaction
lag.
