I have a TB Woods SW1 model SW1C1S015H02 hooked up to a 2hp 220v 3ph motor.
The reason for this combination is that I only have a 120v power available to run a 2hp 3 phase mill. The VFD is only rated to 1.5hp, 1.1kW and the motor is 2hp, 1.5kW. I was told that this would be ok so long as I didnt mind the loss in motor hp.
So far everything is hooked up as I could surmise to be correct. The VFD powers on and I am able to power up and control the motor. But something is definitely not right. W/some VFD adjustments, the motor is only able to reach a max of 40Hz if the Acceleration Ramp Time is set to a slow 60 seconds. The VFD trips if acceleration is set faster or if pushed past 40Hz. The VFD will also trip if ran more than about a minute(at any speed) due to an "over-current on drive output" or "motor thermal overload". Also the motor spindle seems to slow down at around 10Hz then speed up again past that. Randomly, the motor will self reverse direction at around 3Hz.
Needless to say - though the wires are hooked up - its definitely not right. I have moved the 3 motor wires to every combination to U,V,W to no avail. Below is my current wiring. Any help would be greatly appreciated.
