The Spin1X is (as I understand it) basically the PWM-to-Analog stage
from a Mesa card as a standalone board.
(The 7i76 spindle out does _not_ use PWM, that's a smart-serial digital signal.

Andy just to confirm.
On a 7i76 the 0_10v is isolated from the Mesa card I think. Is a 7i77
similar? I just a bit cagy about connecting up electrically to the VFD
inputs. As I don't want to blow anything.
I'm still struggling to understand how this would work.

The 7i77 is +/- 10V so you would want to use an "abs" module to make
sure that the 7i77 analogout doesn't see the negative spindle speed
commands
Then se
hey everyone
I have a fanuc velocity amp which I have hacked and found the 0-10v speed
reference input on it. the amp takes in 0-10v and Rev/FWD inputs. this is
ideal to control with a Pot and two switches and how I am currently
controlling it. On my cnc mill i used a 7i76 card and the virtual
18 matches
