I am running a toshiba 3 axis tb6560 board, and it has a relay, in/ground/out
I ran it with a pwm 0-10 volts and it has an adjustable knob poten. when i had a 0.4 kw spindle 12v, and i did the rpm manually .

I switched to a 2.2 kw spindle and vfd HY

I know there are four things on the vfd; 2 are on/off which is (FOR and DCM )
I know there are 2 for the 0-10 volt rpm control of the 400hz freq (V1 and ACM)

My question is what four wire do i use on the tb6560?

Can I only use the relay and do on and off for the spindle control?, or is there a way to do both, spindle control and rpm control ?
Thanks!!
