Hi
We have bought a new VSD and we are testing in workshop before installing on site. We have connected the control signals as attached. We have set a min frequency of 38 Hz. We have connected a small motor 0.37 kW for testing. When we press start push button, we can hear the VSD fan running as if the VSD has started but the motor does not rotate. We have set the kW and current the lowest possible in the VSD.

When we press emergency push button, the VSD stops. Can you please tell me what may be wrong and why the motor does not rotate?

We have contacted Schneider technical dept but have not receive the right advice up to now.
