Remotely controlling the Huanyang VFD with LinuxCNC over RS485 Modbus

Get a Motor + VFD set: http://bit.ly/2IO0cP5

1. Get a couple of those cheat RS485 USB Adapters
2. Connect to VFD with a twisted pair cable
3. Configure the VFD like this:

PD001 = 2
PD002 = 2
PD163 = 1
PD164 = 1
PD165 = 3

4. Make a fresh LinuxCNC config without any spindle pins
5. Put into the custom.hal:

loadusr -Wn vfd hy_vfd -n vfd -d /dev/ttyUSB0 -p none -r 9600

net spindle-cmd-rpm-abs =▷ vfd.speed-command
net spindle-cw motion.spindle-forward =▷ vfd.spindle-forward
net spindle-ccw motion.spindle-reverse =▷ vfd.spindle-reverse
net on motion.spindle-on =▷ vfd.spindle-on

7. Change the ▷to pointy brackets which youtube wont let me put in my description ...
8. Put into the custom_postgui.hal:

setp vfd.enable 1
