I am new to this forum and getting this in depth with the electronic side of things.
I run a Flashcut CNC control box with PWM out to a Digispeed polarity protected/isolated speed controller to a KBIC manual motor controller.
Presently I have to set my RPM 2800-0 as opposed to 0-2800 as I only have isolated +5V and common ground out from CNC box, no hi low choices in software.
This is causing the spindle to start 100% when I power up if I forget to switch to manual and off at power down the day before, potential safety issue.
Wondering if with only the isolated +5V PWM and common ground out there is a way to reverse the polarity of +5V PWM signal?
Thank you for your time,
Mike
