Huanyang FC01 modbus

Hi guys, previously I've been using hy inverter which worked well with hy_vfd via modbus. After it failed I've bought huanyang FC01 and connected the same way. Unfortunately with the same configuration it didn't work straight out of the box as I expected. Did anyone succeed with FC01 model? 

The manual www.huanyangvfd.com/wp-content/uploads/2.../FC01-Series-VFD.pdf says it uses Modbus, did you try that?

Same as the previous one. Same wiring. Same usb adapter.

Try Modbus. hy_vfd isn't Modbus.

You mean like writing my own hal component?
Where can I find some more info?

Based on modbus specification in this inverter manual I wrote a python program to steer vfd. Things so far I did (maybe useful for someone) :
1)connect Huanyang FC01 to 485-usb and then to rpi4 with linuxcnc
2)set jumper 4 to On on vfd to enable communication
3)program vfd:
P00.01 = 2
P00.06 = 8
P00.07 = 1
P00.09 = 0
P14.00 = 1
P14.01 = 3
P14.02 = 0
4)start my vfd_monitor

After those steps I was able to connect successfully and drive my spindle.

Next step will be to integrate it somehow with linuxcnc
