Function Parameters
AC10 Inverter
When FA07=1, the sleep function is invalid.
FA09 Min frequency of PID adjusting (Hz)
Setting range:
F112~F111
Mfr’s value: 5.00
The min frequency is set by FA09 when PID adjusting is valid.
FA10 Sleep delay time (S)
Setting range:
0~500.0
Mfr’s value: 15.0
FA11 Wake delay time (S)
Setting range:
0.0~3000
Mfr’s value: 3.0
FA18 Whether PID adjusting target is changed 0: Invalid 1: Valid
Mfr’s value: 1
When FA18=0, PID adjusting target cannot be changed.
FA19 Proportion Gain P
Setting range:
0.00~10.00
Mfr’s value: 0.3
FA20 Integration time I (S)
Setting range:
0.1~100.0
Mfr’s value: 0.3
FA21 Differential time D (S)
Setting range:
0.0~10.0
Mfr’s value: 0.0
FA22 PID sampling period (S)
Setting range:
0.1
～
10.0
Mfr’s value: 0.1
Increasing proportion gain, decreasing integration time and increasing differential time can
increase the dynamic response of PID closed-loop system. But if P is too high, I is too low or D
is too high, system will not be steady.
PID adjusting period is set by FA22. It affects PID adjusting speed.
The following is PID adjusting arithmetic.
FA29 PID dead time (%)
0.0
～
10.0
Mfr’s value: 2.0
FA29, PID dead time has two functions. First, setting dead time can restrain PID adjustor
oscillation. The greater this value is, the lighter PID adjustor oscillation is. But if the value of
FA29 is too high, PID adjusting precision will decrease. For example: when FA29=2.0 and
FA04=70, PID adjusting will not be valid during the feedback value from 68 to 72.
FA58 Fire pressure given value (%)
Setting range:
0.0~100.0
Mfr’s value: 80.0
FA58 is also called second pressure, when the fire control terminal is valid, pressure target
value will switch into second pressure value.
