According to the YL620 manual, output current is in register P11.02. With modpoll, you can read single registers or a block of registers. I never used bmpoll. This may be stating the obvious, but make sure the modbus adaptor is set to the same serial parameters as the VFD. As for speed, my VFD has a minimum speed it can run, which is set in one of the registers. Yours likely also has a minimum allowable speed.
I have no problems with readings via modbus, I can read the data that interests me without any problems. The problem is only with the reading of the amperage. The value should be in register 0x200c or decimal 8204, but vfd shows the value 0.0, on the front panel also shows 0.0 so I think this is the problem of the inverter.
Hey Folks... Thankyou so much for this thread. I'm trying to setup yl620a... By following the thread I could reach to a point where I edited my axis configuration with the steps listed by @oficinerobotica. UI comes up I can see spindle controls.
However, I could not get it to run any gcode as it gets stuck after rapids and spindle start. I suspect it could be due to older overrides in the AXIS configuration which I took as base ?
Would anyone be kind enough to share the config folder to me to check whats needed and whats not.
Another issue I have is that pncconf does not show me qtdragon_hd option to configure. However I have it installed in /usr/share/xxx.
what shall I do so that I can get this option in pncconf .

This sounds like a problem with spindle-at-speed.
Have a look in your HAL file to see what is connected to spindle.0.at-speed (and also what is connected to that, and so on)
Thanks... I've done a clean qtdragon pncconf install and then changed to qtdragon_hd.
In the last step in my configuration I do not have a postgui_call_list.hal file. Instead I have custom_postgui.hal, qtvcp_postgui.hal files.
Ok... so I added it to custom_postgui.hal. But on cyclestart after rapids machine gets stuck with spindle on.
Attached screenshot. It shows line where it gets stuck.
