General Mach Discussion / Re: Converting from ncstudio
« on: November 22, 2022, 05:48:30 PM »I need some help connecting mach3 board to vfd.
The new board has a spindle on/off and 0-10v PWM
any ideas on how I wire this?
Actually quite simple
1. You need (maybe later!) another cheap (Arduino type ) relay to be switched by P16 for M4 (spindle counter-clockwise)
2. As is you can only do M3 (spindle spinning clockwise).
3. The relay jumper for Pin 17 on your BOB must be ON (connected)
4. You will need a small capacitor and a ferrite core for your 0-10V connection to the VFD (read VFD Manual).
5. Relay(s) to be connected to ANIn1 and ANIN2 with Common DIGITAL GROUND.
6. F0.01 on your VFD will need to be switched to 2 (from 0).
7. You need to define Output#1 in Mach3 to port 1 pin 17 and Output#2 to port 1 pin 16 (maybe later).
