5-61

5.11 Group A: PID Parameters

A - 00 PID Visszacsatolási terminál kiválasztása Factory Setting: d 0

Settings d 0 Disable PID function

d 1 Negative feedback 0~10V AVI

d 2 Negative feedback 4~20mA ACI

d 3 Positive feedback 0~10V AVI

d 4 Positive feedback 4~20mA ACI

! 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 Visszacsatolási érték erősítése Factory Setting: d100

Settings d0 to d999% (d100 means gain value is 1) Unit: 1%

! To Adjust feedback detective gain value. It is used to adjust target value error.

A - 02 Arányosítási növekmény beállítása (P) Factory Setting: d100

Settings d0 to d999% (d0: disable) (d100 means gain value is 1)

! This parameter is used to determinate error gain. If I = 0 and D = 0, doing proportional

gain operation.

A - 03 Integrális idő (I) Factory Setting: d100

Settings d0 to d999 (d0: disable) Unit: 0.01 second

! 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 Differenciális idő (D) Factory Setting: d0

Settings d0 to d100 (d0: disable) Unit: 0.01 second

! When this parameter is set to gain =1, PID output is differential time. At this time, error

value –error value of the preceding item= additional respond speed and it is easy to have

over compensation situation.
