Input Terminal for PID Feedback
Factory Setting: 00
Settings 00 Inhibit PID operation; external terminals AVI, ACI might be used
for V/F control if required (Pr.02-00).
01 Input negative PID feedback from external terminal AVI (0 to
+10V).
02 Input negative PID feedback from external terminal ACI (4 to
20mA).
03 Input positive PID feedback from external terminal AVI (0 to
+10V).
04 Input positive PID feedback from external terminal ACI (4 to
20mA).
 Note that the measured variable (feedback) is the output frequency (Hz). Select input
terminal accordingly. Make sure this parameter setting does not conflict with the setting for
Pr.02-00 (Master Frequency)
The negative feedback is (+target value – feedback).
The positive feedback is (-target value + feedback).
10 - 01
Gain Over the PID Detection Value
Factory Setting: 1.00
Settings 0.00 to 10.00 Unit: 0.01
 This is the gain adjustment over the feedback detection value, which is utilized in
adjusting the inaccuracy between the target value and the measured value.
10 - 02
Proportional Gain (P)
Factory Setting: 1.0
Settings 0.0 to 10.0
 This parameter specifies proportional control and associated gain (P). If the other two
gains (I and D) are set to zero, proportional control is the one effective. With 10%
deviation (error) and P=1, the output will be 1/6 x P x10% x Master Frequency.
10 - 03
Integral Gain ( I )
Factory Setting: 1.00
Settings 0.00 to 100.00 sec
0.00 disable
 This parameter specifies integral control (continual sum of the deviation) and associated
gain (I). When the integral gain is set to 1 and the deviation is fixed, the output is equal to
the input (deviation) once the integral time setting is attained.
