Regulated current to pilot proportional solenoids from MC050-10

[MimmoA]

Dear Sirs,
 
we are programming a Sauer Danfoss controller MC050-10 to manage an electro-hydraulic crawler drill prototype. In particular we have to pilot a variable displacement pump equipped with one electro-proportional regulator that has two proportional solenoids. Each solenoid must be actuated by 24VDC electric current linearly variable from 200mA to 560mA.
Could the MC050-10 controller provide in output (i.e. from the pins 37..40) a regulated current with these specifications?
Alternatively, could we use the input pins 27...30 like trimming potentiometers, so the 24VDC electric current that supplies the two proportional solenoids can be regulated in the range 200mA - 560mA?
Ultimately, in our intention, we would like to adjust the pump displacement regulator by our JS6000-CAN joystick rocker - that is obviously connected to the MC050 controller - without an external current regulator or analog amplifier. In other words we would like to get by the controller a regulated current for the actuation of proportional solenoids.
I hope I was clear enough.
 
Thanks in advance.
 
Best regards.

I would use a 3 point sensor function block to input my joystick data and a proportional output function block to scale my outputs.

Good luck.

For the output, you could use the pins 37 to 40. With PinConfig at 4, you will have a PWM output that can vary the current from 0 to 3A.

I would suggest that your MC050 should be fed by the same 24V DC input as the solenoid.

For the scaling, use a scale component that scale the input (0-10000 variable rocker joystick switch) from 0-10000 to 2000-5600 and send the output from the scale component to the OutputValue of the pin 37 by example).
