Gday All.
About two years ago I bought a Huanyang VFD/phase changer for my Bridgeport clone mill. I also fitted an almost new 2.2Kw 3 ph motor.
Spent a fair bit of time getting it all set up and until today I haven't had a problem with it. I have a remote mounted speed control pot as well as a remote mounted reversing switch with the centre being another motor "off". I also have two remote mounted start/stop switches.
I have only had the VFD set up to use a frequency range from 50Hz to 100hz.
I haven't used the mill much since I fitted the VFD. In fact until this arvo I haven't used it since late January when it was working fine. When its not in use the machine is unplugged from the wall socket.
So this arvo I went to do a small job and thats when I discovered the VFD is not working properly now.
1) I no longer have speed control at my remote controller
2) The does the direction switch work properly. The motor runs but I think its only running at 50 Hz. The direction switch doesn't switch the motor off when I put it in the centre "Off" position. If I stop the motor using the stop button and then change the direction switch, then restart, the motor runs the other way.
Bugger.
Now I haven't had a chance to have a look at it yet so I cant supply any more info at this point, but I thought I'd put this up in case someone else has knowledge of an issue like this.
I'm really hoping its just some sort of programming glitch and not a component failure
As I haven't touched it from a setting up perspective for over 2 years its going to be a bit like starting out from scratch again.
Any info would be greatly appreciated.
I'm hoping to have some time to have a look at it tomorrow arvo.
