Hi gentlemen
I have an older Teco 1hp VFD 230 single phase to 230v three phase VFD. I had been using this VFD with a 3/4 horse motor with no problems. I upgraded to a 1 hp motor and I have a problem that I can't figure out and don't understand. When I attempt to start the motor at any frequency, it turns slowly in the wrong direction most of the time. Sometimes but rarely it will start and come up to speed in the correct or reverse direction. I have looked at all settings and can not solve the problem. Can you make any recommendations please so it will start in the correct direction as it used to when connected to the 3/4 hp motor? Both of the motors are GE 3 phase motors and are wired correctly. I have tried re-arranging all three phase lines with no change in the outcome. The only item I changed was the motor. When it does start up and run at the correct speed it performs properly, a variable speed, sufficient power no weird noises and no smoke escaping.
Here is what the unit is
