ABB ACS355 18.5kW taking input voltage of around 410V but no voltage in the output ports. Motor doesn't run

An ABB squirrel cage induction motor is used. That is of 25hp rated. The motor is installed in a wind tunnel.
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.
