CV3100 series and MINI series high performance general purpose inverter instruction manual
PID ration given by summation of AI1 and AI2 provision.
8：AI1-AI2
PID ration given by difference of AI1 and AI2 provision.
9：MIN｛AI1,AI2｝
PID ration given by the smaller one of AI1 and AI2.
10：MAX｛AI1,AI2｝
PID ration given by the bigger one of AI1 and AI2.
P6.02 PID Feedback channel selection
Setting range
Note: The value of provision channel set can't be same as feedback channel, or else
the ration will be same as feedback quantity, deviation value is 0, and PID can't work
normally. In addition, there is without any sense if Feedback channel is set between 0
and 3.
P6.03 Specified digital quantity setting
Setting range
When PID specified channel selection is digit setting （ P6.01=1） , this parameter is used
for setting the digital quantity value of PID control.
For constant pressure warter supply close loop control system, setting of this
paramerter shall base on carefully considerating the relationship between capacity and
output feedback signal of manometer far away from the inverter.
For example, if the capacity manometer is 0-10Mpa and we need 6Mpa pressure
toward 0-10V(0-20mA) voltage output, we can set digital quantity to 6.00V in order to
get pressure of 6Mpa after stable adjustment of PID.
