KE300A Inverter Parameter Description
135
Group PA PID Function
PID control is a common used method in process control, such as flow, pressure and temperature control.
The principle is firstly to detect the bias between preset/given value and feedback value, then calculate
output frequency of inverter according to proportional gain, integral and differential time. Please refer to
following figure.

This parameter is used to select the given channel of PID target value
This value is an actual physical quantity. It must correspond to the measure range. For example, if the PID
keypad given value is 0.3Mpa, PA-01 should be set to 3.0.
