Fieldpoint FP-PWM-520

What is the minimum pulse width that can be generated by the FP-PWM-520 module on the 1ms time base and can each individual channel be sychronised to each other programatically?

Hi,

The minimum pulse with you can reach with the 1 ms period is of 10 microseconds.

The channels on the FP-PWM-420 cannot be exactly sinchronized between each other, the pulse generation mechanism of the FP-PWM-520 is controlled through sofware, not hardware, so we cannot assure that the pulses will start at the same time... Even if you create a multi-channel item to write to both channels, you will still have a difference of phase between the channels (1 - 2 ms)...

You can also look at this discussion forum document here :

I hope it helps
