Hello Friends of LinuxCNC,
i think i am here in the right address, about VFD and Modbus RTU
I use LinuxCNC 2.9.2 and i try to get to run a VFD ( Powtran PI500) on the Modbus RTU.
I found something about PI500 in the description, but i think thats isnt the driver.
linuxcnc.org/docs/2.9/html/man/man1/pi500_vfd.1.html
My goal is to get to work the first one, then i get 2 others in modbus RTU as well ( 3 Spindle = slave 1; slave 2; slave 3 )
Has anybody an idea, how is to do for a PI500 VFD?
Thank you so much in advance

Best regards
Reinhard

If this is just standard modbus then there are several options. There is a brief description of the options in this docs section:
linuxcnc.org/docs/stable/html/drivers/mesa_modbus.html
(Note that that specific manpage is for what it probably the highest-effort option...)
