Chapter 6 - Parameter Description [FU2]
6-27
FU2-51: PID Feedback Signal Selection
FU2-52: P Gain for PID Control
FU2-53: I Gain for PID Control
FU2-54: D Gain for PID Control
FU2-55: High Limit Frequency for PID Control
FU2-56: Low Limit Frequency for PID Control
Select the feedback signal for PID control. This can be set
one of ‘I’, ‘V1’, ‘V2’ according to the signal (current or
voltage) and the terminal (V1 or V2).
Set the proportional gain for PID control. When P-Gain is
set at 100% and I-Gain at 0.0 second, it means the PID
controller output is 100% for 100% error value.
Set the integral gain for PID control. This is the time the
PID controller takes to output 100% for 100% error value.
Set the differential gain for PID control.
This is the frequency at which the output frequency is
limited under during PID control.
This is the frequency at which the output frequency is
limited over during PID control.
FU2-57: PID Output Inversion
FU2-58: PID Output Scale
FU2-59: PID P2 Gain
FU2-60: P Gain Scale
This code is used to inverter PID controller output.
This code sets the scale of PID controller output.
This code sets the second P-Gain for PID control. The
second P-Gain is can be selected for PID controller by
setting a multi-function input (I/O-12 ~ I/O14 or EXT-02 ~
EXT-04) to ‘Open-loop’.
This code sets the scale of P-Gain and P2-Gain. (FU2-52,
FU2-59)
☞ PID output value can be set to ‘0’ by setting a multi-
function input terminal (P1 ~ P6) to ‘Open loop’ in I/O-
12 ~ I/O-14 or EXT-02 ~ EXT-04.
☞ The accumulated value by I-Gain can be set to ‘0’ by
setting a multi-function input terminal (P1 ~ P6) to
‘iTerm Clear’ in I/O-12 ~ I/O-14 or EXT-02 ~ EXT-04.
