Code Description / LCD
C00 Filter time of speed-loop
It defines the filter time of the speed-loop. The range is 0.01~100s.If the value is too great,
the
Control is stable but response is slow; if the value is too little, the system response is rapid
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
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
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
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
