Question. Talking of switching drive directions:
Servo drive. I'm using a small opto module to switch the digital input on/off for cw/ccw - m3/m4.
It's 5v in 24v out direct connected to uc300eth port #5. Works great, however.
What do you think about using the cw/ccw inhibit along with it as an extra measure?. (more just because it can maybe).
So:
ccw=on - cw=inhibit. M3.
cw=on - ccw=inhibit. M4.
I'd use the opto module as a series connection to 2 outputs M3+CWL, M4+CCWL.

Worth bothering or not?.
Thnx.
