Hi all,
I'm working on a machine with 7i96s for brains and a 7i75 for IO. I'm adding a fuling BD612 VFD so i can use the high rpms that the spindle is capable of, and I'd like to do this via modbus.

I'm aware of the hm2_modbus and mesambccc manpages as well as the docs page Mesa Modbus, but... I can't tell if they are referring to the same thing. It seems clear that vfd_modbus and mb2hal are different ways to do this.
I'd be grateful if someone could confirm that these refer to the same thing or different things...

It's clear that hm2_modbus and mesambccc are parts of the same system - does anyone have an example file(s) for setting these up? I'm happy to spend hours with the manpages and guide but get on far better reading and tweaking existing code, than trying to write it myself from scratch.

I've flashed the 7i96s_pktv3.bin bitfile successfully, not sure of next steps. 

Many thanks,
Andy

 

Does the drive itself power down on a fault?
