Configuring Acorn for 0-5V spindle control
Posted: Fri Dec 11, 2020 2:01 pm
I have drilled down in multiple posts to get clarity on configuring Acorn for 0-5V spindle control. It appears there are four possible solutions:
1) Throw away your 0-5V spindle drive and get a drive and motor that works on 0-10V (allow me a little humor here) = unacceptable
2) Install a KBSI-240D. Cost: $60 - $100 depending on source, shipping etc. = marginally acceptable if you don't mind spending the $$
3) Make a simple voltage divider circuit with a couple of resistors. = cheap, simple, easy, acceptable, but not an elegant solution IMHO.
4) Someone has alluded to the possibility of editing the PLC code by changing the DAC values. = elegant, no cost (except time and possible fear of mistakes).
So, is it possible to edit the PLC code to cause Acorn to output 0-5V, or not? If so, what values? Even better, a screen shot of the edited code - unless it is classified beyond my security clearance.
Thanks guys,
Love y'all
