I have got a Huanyang P2 vfd 1.5kw
it works well in everyway but now I need to let it communicate with mach3 via its RS485
I have got the RS485 to usb adaptor (ch340 chipset)
its driver installed normally @ port 4

I went through routes trying this to work
1. via the Huanyang vfd plugin Mach3 plugin for Huanyang VFD | Le royaume d'éole

2. via mach3 modbus

please note that this P2 vfd does have :

0: non-standard
MODBUS protocol
1: standard MODBUS
protocol
2: ASCII

I have also tried to alter the wires of the RS485 adapter in both trials, did not work also

the port is open but no communication occurring
I am assuming the mach3 plugin will not work on this vfd as it is not created for it
the modbus on mach3 is very complicated and have a lot of setting that i dont understant
All I need is to control on/off and speed control via mach3

hope to get some help here
here is the vfd manual
