Standard default output: DA1 default 0 ~ 10V; DA2 default 4 ~ 20mA.
V-3-2 Connection:
The voltage meter showing the frequency is connected to the DA1 and GND
terminals of the inverter, and the ammeter is connected to the DA2 and GND terminals.
V-3-3 parameter setting:
When the system requires the drive DA1 0-5V signal output, you need to set the parameters as
follows:
No.

Note: DA1 jumper cap on drive control board needs to be shorted to V terminal.
When the system requires DA2 to provide 4-20mA signal output, the following parameters need
to be set:
No.
