Hi everyone,
Now I used Micromaster 430 controlled by a PLC. I set parameters as follows:
P0010: 0
P0100: 0
P0700: 2 (using BOP-2)
P0701: 1 (start)
P0702:12
Terminal 3+4: Connected to Analog output of the PLC
Terminal 5: connected to 24V via a relay which is controlled by the PLC
DIP switch1 on (analog input1 with 0-20mA)
When I turn on the relay to power to terminal 5, the inverter runs about 5 seconds, then stop automatically while terminal 5 is still powered.
There are no fault and no alarm. I checked the parameter P0947 and P2110 with value 0.
Especially, when I set P0700 = 1 (using Start button in Panel), the inverter runs well without stop automatically.
Please give me some solutions.
