Breakout board to Telemechanique Altivar 18 wiring (Mach3)

Thanks for the quick reply. I tried feeding 24v from the inverter to the 12-24v input but it just lit up a led on the BOB - not sure what the purpose of the 12-24v input is.

I haven't altered anything in the inverter programming for the pot - you may have hit on it. I've been using these things for years, don't know why I didn't think of it straight away. I'll check it in the morning. Thanks.

I know nothing about that inverter, but for my Chinese inverter I had to set parameters to accept a 0-10V input (rather than front-panel controls). But, yes, the idea is to connect the 0-10V output (and ground) to the COM/A12 on the inverter.
