F. 20-01~05 = 5 Communication control signal switch reserve.
G. 20-01~05 = 6 PID function disable
When on, the PID function is disable, drive doesn’t concern about the
sensor feedback, in the same time, output frequency= 0.
H. 20-01~05 = 7 Forced operating frequency
This function is match with PID disable function to start the forced operating
frequency. More detail please refer to 18-C.
(30)：20-6~7 Multifunction output terminal:
20-6 : RELAY1(R1C, R1B, R1A terminal inTM2)
20-7 : RELAY2(R2B, R2A terminal inTM2)
0: Run
1: Auto restart
2: Auto restart
3: Momentary power loss
4: E.S.
5: Free run stop
6: Motor overload
7: Inverter overload protection
8: High/Low pressure alarm
9: Power On
10: PID feedback signal offline
11: Over torque detection
(31)：20-8 Source of bias target pressure
0 : Disable
1 : AIN
2 : VR(15-6 password is a must)
20-9 Range of bias target pressure 0.0 – 10.00
1.) 20-8 = 0 : Disable
2.) 20-8 = 1 : Voltage command is given by TM2 AIN, the target pressure cannot
be set from keypad now, target pressure will adjust according to 20-9 setting range
and AIN voltage, and it is based on 5V, it decreases (by ration) according to the AIN
voltage if it is lower than 5V, it will increase (by ration) if higher.
EX : 18-0 (Pressure setting) = 5.0 (Bar)
20-9 (Range of bias target pressure) = 3.0 (Bar)
If AIN input voltage 8V Î Target Pressure = 5 + ((8V-5V) / 5) x 3(Bar) = 6.8(Bar)
If AIN input voltage3V Î Target Pressure = 5 + ((3V-5V) / 5) x 3(Bar) = 3.8(Bar)
