Hi guys, i have never had to do a PWM Output or input before
i have a Device that to dimm the lamp output from the ballast, the ballast has a 24V PWM input
i need my PLC to output this to the ballast
but i dont want it a dial like the manufacture advised
i want to create 3 settings for power output of lamp
so lamp will run at 3 power settings 50%, 75% and 100% now i have noticed by default if i just apply 24V dc directly to this contact its allow full power
so is the PWM just dropping the voltage ?
and the settings of the PWM in the click sofware confuse me
it wasnts cuty cycle ? is this where i specify the 50,75 and 100 ?
sorry to be a pain but i really want to get my head around this
