Electronics for New Machine + Chinese Spindle + VFD

[njhussey]

Thanks NJ...

I read that somewhere to, but what's the difference?
Surely if you cut the power to the VFD with a relay or with a switch your still cutting the power ?

Thanks

The absolute correct way to do it is to use a relay to tell the software to say stop to the VFD, meanwhile a timed relay cuts the power after a second or so by which time the stop signal has reached the VFD...
