|Thread: Warco WM250v VFD. Start problem.|
Thanks for the pointers.
I'm pretty certain it's not the chuck cover switch as the fan slows when this is switched off
I'll open up the front and check the screw terminals as you suggest.
i have a WM250v (the one with the VFD) that has been working fine for several months.
Recently it started intermittently refusing to start. The main fan is running fine and if I toggle the direction to off, open the gear guard or toggle the spindle guard micro switch the fan slows so it is ot these switches
The problem is intermittent but getting more frequent when I hit the green 'go' button nothing happens I can hear the relay trigger it the spindle does not start when I hit stop and then start again it may or may not start
Eventually I can get it to start and works fine for that operation the next operation is pot luck if it will start
Very recently (yesterday) it has started stopping the spindle while turning the spindle with stop and start on its own until I cycle the red and green then I am back to pot luck if it starts
Anyone have any experience of this fault I am assuming there is some safety mechanism or sensor that is playing up but don't want to open the machine up without an idea what to look for
All help welcome
