supply
10V reference power supply
Max. output current: 50mA
As the adjusting power supply of the
external potentiometer
Potentiometer resistance: 5kΩ above
1. Input range: AI2 voltage and current can
be chosen: 0 – 10V/0 – 20mA; AI3: -10V –
+10V.
2. Input impedance: voltage input: 20kΩ;
current input: 500Ω.
3. Voltage or current input can be set by dip
switch.
4. Resolution: the minimum AI2/AI3 is
10mV/20mV when 10V corresponds to
50Hz.
1. Output range: 0 – 10V voltage or 0 –
20mA current;
2. Voltage or current output is set by
jumpers or toggle switch;
3. Error ±1%, 25°C;
4. There is only one AO1 for VFDs ≤ 2.2kW.
1. Contact capacity: 3A/AC250V,
1A/DC30V;
2. Please note that it should not be used as
high frequency switch output;
3. There is only one relay output for VFDs
≤2.2kW.

Use U-shaped contact tag to set NPN mode or PNP mode and the internal or external power
supply. The default setting is the PNP internal mode.
