Exactly why you should remain silent or at least think before telling people that something can't be done like you are an authority on it when really you have no clue or experience yourself other than something you read.!
The fact it's not the best idea has nothing to do with anything, it can be done and that's what was basically being asked but luckily Neale is no duck egg so knows better but if this had been a new user then your post could have sent them off in directions they didn't need to go. If you or anyone is not 100% on electrical matters they should either state this when dishing out advice or keep quiet.
I've done far stupider and costly cocks so don't go into hiding over it, your not the first and won't be the last to do it.
Sorry, Neale, I missed this.!
I always control a relay Neale for a number of reasons, isolation being one but I can also control several things at the same time the spindle turns on ie water pump etc.Last edited by JAZZCNC; 12-05-2022 at 09:00 PM.

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.

For what purpose.? I see none as it can only spin in one or the other direction never both together so no need. And if the servo is clever enough then it would throw either a fault or inhibit itself if both inputs become active at the same time.
I'm guessing this is for a spindle drive.? In which case, if your hell bent on using the inhibits use them when changing tools either via a switch or on-screen button.!-use common sense, if you lack it, there is no software to help that.
