Nobody else having this problem?

The active check box doesn't change the PWM direction.

General Mach Discussion / Mach 3 PWM signal inverted?

« on: February 23, 2016, 11:57:19 AM »

I need help with the PWM signal from Mach3.  I am hooking up a Super PID and the PWM signal is inverted.  When I send a M3 S5000 I get 25,000 rpm and when I send a M3 S25000 I get 5,000 rpm.  I have tried changing the Pin 14 output from active High to active Low but the signal does not invert.

Am I doing something wrong or do I have to build an inverter to go between the PWM and the PID?

Thanks,

Joe Lawrence
