Good to see you got it going. Looks to be going at a respectable speed too.
I spy a ring hanging on the left ballscrew, so either it just got married or a locknut has fallen off? It looks like you'll have to put some threadlock on them if tightening the two nuts against each other isn't working.
If you press the sideways arrow (<<) key on the VFD it will scroll through various different useful readouts, including rpm. I tend to leave mine showing current since that's a good indicator of if the cutter is operating normally.
Also, if you haven't already, check that PD141,PD142 and PD143 are set correctly - these are the motor voltage (220), rated current (8) and number of poles (2) respectively. In addition if you want to save a couple of seconds waiting for the spindle to get up to speed and stop you can adjust PD14 and PD15 which are the ramp-up and ramp-down times. You should be able to set both to a couple of seconds safely, but don't go too low as it will draw too much current and needlessly stress the system.
Good eyes Jonathan, I hadn't noticed it came off!
I had set PD141 to 240V since I thought that was meant to be the over-voltage protection for the mains. I'm better to keep it at 220V, then?
I'll have to play with the VFD a bit more, the manual was hard to decipher.
Thanks again, I'll maybe post some videos again when I do more cutting.
