VFD Feedback

Hello, I'm wondering what is the best approach is to read/display the spindles current voltage, amps, rpm, status and error codes?

linuxcnc 2.9
Mesa 7i76e - VFD connected to TB4
Delta VFD-E
SilverDragon

thanks

There is a component for the delta VFD-b:
linuxcnc.org/docs/2.8/html/man/man1/vfdb_vfd.1.html

i don't know if it will work with your VFD.

Thank you but I'm not sure of the hardware connection for that option? Would that be using the VFD's RS-485 interface and a sserial signal converter for the 7i76e?

thanks

yes rs485
typically I think you would use the rs232 port or USB port with a converter.
