Hoping that someone with greater experience / electrical knowledge might be able to offer some advice. I hooked up a TECO Westinghouse L510-203 frequency inverter to a 3hp 3 phase motor this evening (dust collector blower). The VFD flashed "5.00" before I ran through the modes to set up and or check factory settings, then "run". The impeller spun in the correct direction but at a small fraction of the 3450 RPM I was expecting. I couldn't guess the speed but it wouldn't move dust.
Here are a few of the setup parameters I've confirmed:
- 00-05=1 for keypad controls for potentiometer (tried turning knob)
- 02-03= 3450 RPM for motor rated speed
- 02-04= 230 motor rated voltage
- 02-06= 60Hz motor rated frequency
I hooked the VFD up to a second 3ph 3phase motor and had the same issue.
Something I haven't mentioned is that i checked both motors to see if they were wired for high voltage (460v), and I'm not sure what to make of what I saw. The first motor box was a bunch of wires & nuts without a board or diagram so I moved over the second motor. It had a nice diagram on the inside cover illustrating the high and low wiring configurations with three rows and two numbers in each row.. but the actual board was two rows of 4 connections so the diagram wasn't of help. I can say the second motor is a "Wye" configuration with 3 pairs and the 4th has 3 wires (9 total).
Sorry for the long post but I wanted to cover what I've checked so far. Any help would be appreciated.
