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
gain value is 1)
Factory Setting: d100
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
