I've been trying to get my vfd to be controlled from linuxcnc with a c41 pwm to 0-10v board. I'm getting my 0-10 ok, but i can't get the VFD to turn on. I've got it wired to VI and acm. All the settings i can find are for the 24k spindles. Can someone post the necessary settings for the above setup? It is an 1800rpm, 2hp, 220v., 60hz, 3ph motor. I'd like it to run at 3600rpm max or so, 120hz. It runs fine if I set it manually from the panel, just won't do anything from the 0-10v. I've tried quite a few setting combinations with no luck so far. I'm hoping someone has successfully set one up in this configuration.

Thanks,

Mike

You also need to:
1) Put jumper between FOR (forward) and DCM. This tells VFD, that you want to spin CW. You can go fancier with relays, but jumper will do.
2) Configure VFD to accept input from VI, not from operator panel. I believe for you VFD, you have to set PD01 and PD02 to 1 (default should be 0).

Take voltmeter and measure voltage between VI and ACM. Do you have anything between 0-10V there? Does it move, when you dial speed?
