Spindle Frequency?

Post by marlondave »

I bought and installed a new 1.5kw water-cooled spindle with an inverter to run it. Now whenever I switch the spindle on it triggers my limit switches (in Mach 3) and I can only reset it when the spindle is not running. I'm virtually at a standstill. Any help? :cry:

Dave...
Things to try:
Add debounce to limit switches
Add line reactor to VFD

Make sure your Spindle and limit switch wiring is all shielded and properly grounded.

I'd also recommend a line reactor. Take a look at Trans-Coil (TCI). I have used them with my ABB drives.
