ABB ACS355 18.5kW taking input voltage of around 410V but no voltage in the output ports. Motor doesn't run
The motor doesn't run. When the drive is started the rpm rises up as asked but the motor doesn't run and the basic panel shows 0 amp current. No fault or alarm is shown.
I am in Bangladesh where there is no repair workshop of ABB.
I am a undergraduate student but the professor gave me the responsibility to fix it. I am not in condition to buy a new drive.
Check the 3 wires from U2,V2,W2 to the motor's terminals ! Do you have a correctly connected motor (star or delta)? Open the motor's terminal box and check for the correct bridges.
After start command, do you have any voltage between U2,V2,W2?
Do you have STO function activated? Do you have a bridges on terminals X1C:STO as in the manual ??
