			Chapter 5 ParametersVFD-S Series
Group A: PID Control
A-00	Input Terminal for PID Feedback
				Factory Setting: d0
	Settings	d0	Disable
		d1	Negative PID feedback from external terminal (AVI) 0 to +10V
		d2	Negative PID feedback from external terminal (ACI) 4 to 20mA
		d3	Positive PID feedback from external terminal (AVI) 0 to +10V
		d4	Positive PID feedback from external terminal (ACI) 4 to 20mA

Select an input terminal to serve as the PID feedback location. Please verify the feedback location is different from the Frequency Set Point location and J1 for selecting ACI or AVI must be in the correct position. (Refer to Pr. 2-00 for detail)

Negative feedback = Positive target value – detection value.

Positive feedback = Negative target value + detection value.

A-01		Gain over PID Detection value
		Settings	d0 to d999 (d100 means gain value is 1)		Factory Setting: d100
	To adjust feedback detective gain value. It is used to adjust target value error.
A-02		Proportional Gain (P)			Unit: 1
		Settings	d0 to d999% (d0: disable) (d100 means		Factory Setting: d100
			gain value is 1)
This parameter is used to determinate error gain. If I = 0 and D = 0, doing proportional gain
operation.
A-03		Integral Time (I)			Unit: 1
		Settings	d0 to d999		Factory Setting: d100
			d0	Disable
When this parameter is defined to gain is 1 and error value is fixed, integral value is equal to
error value as the setting of integral time is attained.
A-04		Derivative Control (D)			Unit: 1
		Settings	d0 to d100		Factory Setting: d0
			d0	Disable
