Just need some help from experts.... can we use the variable frequency drive as a power supply for equipment with 50hz rating since our rated frequency supply here is 60hz? The equipment has electronic control board for the fan blower, pumps and inlet valves. Thanks......

But some customer use to control “other equipment” on the drive. I suggest: - having output choke and short (motor) cable - using (fmax) 50Hz output frequency, (fmin 25Hz) - using the default motor data (e.g.P0305) - P0610 = 0 (Motor temperature reaction) - using V/f-control - using pulse frequency (p1800) 2kHz or 4kHz Then it may be works. Good luck ….
