INVERTER,S PID control mode selection.

PID control mode selection.


the operating method of inverter which adopts  pid control.
0: pid control is disabled.
1:pid control is enabled ; deviation signal is subject to derivative control.
2: pid control enabled ,feedback signal is subject to derivative control .
3 : pid control enabled (frequency command +pid output,deviation is subject to derivative control.
4: pid control enabled (frequency command + pid output,feedback is subject to derivative  control.

note : the pid control function is a control system that matches a feedback  value (i.e..a detected value) to the set targed value, combining proportional (p),integral (1),andderivative (d)control makes control possible even for a mechanical system with dead time.
