Controllers / PWM output, proportional Valve
« Last post by AP on April 17, 2024, 10:40:56 PM »Hello I am new to Danfoss! THANK YOU FOR ANY HELP!!
I am trying to control a proportional valve with a PWM signal, the valve requires a 0 to 600mA.
What are the steps involve in this. as simple as possible?
1. Scaling. the valve is inversely proportional so 0mA= 3000PSI and 600mA=0PSI, I can use y=mx+b or scale function from library.
2. is there a function block needed to output a PWM? or can I send the scaled value to the Multifunctional Output?
3. how is the ping configuration done? Output mode option 3,4 or 5?
Thank you again !!
