This is a great unit. Came very well packed but cable was damaged. Bought it for driving Single Phase motor. Actually works quite well in this application if one is prepared to do wiring modifications to certain start winding motors. (eg Cut-out relay). Capacitor start motors seems to work fine except you cannot reverse single phase motor direction. I coupled the start winding of non capacitor motor (after cutting from centrifugal switch) to the third phase output of inverter.(W). I could then also reverse the motor direction via the front panel control. I still need to know how to port the Inverter Speed to relay contacts TA TB & TC to switch out the start winding once running. This would prevent start winding from overheating and burn-out. Pity NO technical back-up is supplied by Banggood! Will buy more of these. Leon bellair@webmail.co.za

kizosgr Maybe if you set the F047: Relay output terminal function (see page 56) parameter to 86 (see page 110), and use external relay to make the contact from the third phase output of inverter(W) to the start winding of motor... i think the acceleration time it needed to be small, 1-2 seconds max... kizosgr@yahoo.gr
