Hello,
I am trying to figure out a way to get a possibility to quicktest all our Victor 884s and 883s without using the cRIO or any other FIRST hardware.
So I've built a simple timer circuit which gives me a
PWM input rate T = 22 ms
and a PWM puls rate of 1.1 - 2.3 ms (controllable with a potentiometer).
I monitored that signal with a storage oscilloscope to double check this data. The values are correct.
According to that information, it should work fine:

But, with the Victor 883 it doesn’t work at all. It blinks orange, which means no PWM signal.
And with the Victor 884 it only works for reverse and stop. If I come to the puls rate > 1.5 ms - which should be forward - it starts blinking orange very fast (faster then the slow 'no PWM signal' blink)
Do you have any idea what I am doing wrong?
