0: Output frequency before
compensation (0~Max frequency)
1: Output current (0~2 times of inverter’s
rated current)

rated torque)
7: Output power (0~2 times of Inverter’s
rated power)
8: Bus voltage (0~1000V) 9: AI1 (0~10V)
10: AI2 (0-10V/0~20mA) 11: Output frequency after compensation
(0~maximum frequency)
12~14: Reserved 15: NULL
Note:
◆ The inverter has two analog outputs（3004GB and the below models as one signal）.
The output can be voltage or current. The full range of voltage is DC 10V and the
current is 20mA. You can select what to output, and adjust the range according to
your actual need.
◆ The inverter model of 3004GB and the below models have only one analog
channel (AO1).The corresponding P4.18, P4.21and P4.23 all cannot be set.
P4.20 AO1 output range selection
Range: 0,1【0】
P4.21 AO2 output range selection
Range: 0,1【0】
0: 0~10V / 0~20mA 1: 2~10V / 4~20mA
P4.22 Gain of AO1
Range: 1~200%【100%】
P4.23 Gain of AO2
Range: 1~200%【100%】
Note:
◆The inverter output and instrument systems are likely to produce bias, you can adjust
the output gain (AO1or AO2) for the meter calibration and the change of measuring
range.
◆To avoid fluctuations of output in calibrating, you can make the inverter output a
standard signal (set P4.17 or P4.18 to 5 to get DC 5v. It is 50% of the full range) for
AO gain calibration. For example, to calibrate AO1, select the function code P4.22
and press “ENTER” key to enter into the function parameter menu, turn encoder on
the keyboard right
+
or left
-
to set output signal just to 5 VDC .The
modification of P4.22 is valid immediately, and would be saved into P4.22 after
pressing ENTER key. To calibrate AO2 is like the above.
◆If the external instrument has a great bias, the instrument should connect to the
inverter and carry out the actual adjustment.
