(3) set closed-loop presetting frequency function (F3.14, F3.15)
(4) set closed-loop proportion gain, integral gain, differential gain, sampling
cycle, error limit (F3.08~F3.12)
F3.00 Closed-loop run control selection Range: 0, 1, 2 0
0: closed-loop run control ineffective
1: PID closed-loop run control effective
2: Specialized for constant water supply PID control
This parameter is mainly used for implementing one-driving-two water supply
function. If need one driving three or one driving four, please choose a dedicated
water supply substrates to achiveve.
F3.01 Provision channel selection Range: 0~3 0
0: digital provision.
1: VCI analog 0－10V voltage provision
2: CCI analog provision. Can choose 0~10V voltage or 4~20mA current
provision
3: keypad analog potentiometer provision
F3.02 Feedback channel selection Range: 0~6 0
0: VCI analog input voltage 0－10V
1: CCI analog input
2: VCI+CCI
3: VCI-CCI
4: Min { VCI, CCI }
5: Max { VCI, CCI }
When CCI analog input is selected to be current input, it will be converted to
voltage value in the inverter.
6: pulse feedback

When F3.00=1, figure given value F3.03 will be as specified value of
closed-loop control system directly. At this time please setF3.21to 9.999(v);
(1) When the constant water supply function is used on “one –drive-two” system, set
F5.10－F5.13（OC1－OC4）=21.
(2) When the constant water supply function is used on “one- drive-one” system, set
F5.10－F5.13
