A user on the forum is wondering why the base frequency (P04) disappeared:

The commit says that it is never used, but he seems to think that it needs
to be changed when he swaps between spindle motors:
https://forum.linuxcnc.org/38-general-linuxcnc-questions/32903-huanyang-vfd-inverter-modbus-base-frequency#94557
Was the parameter removed because the VFD does not use it for anything?
I might have goofed there.
I'm used to setting VFD parameters via the VFD face plate, not via HAL,
but clearly that's not the only way to do it.
I also found I had to set the max frequency (PD005), but did not have to
set the base frequency (PD004), whatever that is. I noted this in the
manpage.
If there's a good reason to use the base freq i'm open to reverting the
commit that removes it.
