Huanyang sl series VFD support was created by vre
I have a huanyang sl series vfd and i want to connect with linuxcnc via modbus.
There is support for hy series and gt series but no for sl series.
Can be added support for sl series ?
The manual is here

Thank you.

Do the existing drivers definitely not work?

The parameters in manuals are different so do not work.

To be honest I am not sure how the Modbus registers map to the VFD parameters or how Seb worked out which register was which for the GT driver.
Comparing the output bits it seems that the feedback parameters might work but will be mis-named in HAL. For example output power in the GT is bit 7 (and register 0x3006 in the driver) whereas it is bit 6 on the SL, so using the GT driver with the SL the output power might appear on another HAL pin (I was going to say which one, but, actually, I am not sure that it is actually correct in the driver for the GT)
Have you actually tried it?
