Hello,

V700 with V200-18-E3XB

 

Like my title says my PWM output is not working. Which is weird because it was working before. I have a PID controlling a PMW output and it has stop switching. When I use the operand view I do see that the out is set to 1000 but my solid state relay is not switching. I was able to switch the solid state relay by using a memory bit and setting it high.  Thanks for any suggestions!

I think it look's good.

Do you test it?

 

Sorry, my answer is a little incorrect.

I found in your program that you operate with PWM output frequency MI1.

Duty cycle in your code = 0. Then output is not active.

Please SET some constant freqency to MI1.  And run PID with MI2 output (Duty cycle).

Then maybe system start working.
