but perhaps is unstable. So it is necessary to consider the stability and the response speed at the
same time when setting the value
C01
Speed-loop low speed Ti
0.01~100.00
s
0.25
Y
It defines the integral time of the speed-loop low speed. The range is 0.01~100.00s. If the
integral time is too great, response is slow and the control of external disturbing signal become
bad; if the time is too little, response is rapid, but perhaps brings the surge.
C02
Speed-loop low speed Td
0.000~1.000
s
0.000
Y
It defines the differential time of the speed-loop low 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.
C03
Speed-loop low speed P
0~150
%
100
Y
It defines the proportion gain of speed loop low speed segment.And the range is 0~1000%.If
the gain is great, the response is rapid, but too great, surge perhaps occurs; if the gain is too little,
response is slower
C04
Speed-loop low speed shift
frequency
0.0~C08
Hz
7.00
Y
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
Speed loop high speed P
0~150
%
75
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.
C08
Speed Loop And High-

Frequency
C04~Max frequency

30.00
Y
It defines Integral time of speed loop high speed , the parameter and switching frequency at
low -speed optimize the speed-loop PID parameter.
C09

Y
Low-speed segment slip compensation gain。
