I have a Delta VFD and a 2.2kW spindle. I would like to set up control via Mach3, but I don't even know where to start.
I've done a ton of searching but all of the information seems very spread out.
I have experience with RS-232 and RS-485 for serial data and control of cameras.
Here are a few questions;
1. Do I need a plug-in for Mach?
2. Is the ModBus signal sent via the serial port?
3. Do I need an ModBus card or module or is it just wiring the serial port on the computer to the VFD.
Is there a ModBus reference manual for Mach3?
Thanks,
James
