Test rig with automated control of L90 valve

Hey together,

for a customer project I am using two plunger cylinders to simulate ground effects on gage wheels.

Therefore the motion of the cylinders should be one extend, the other retract and the other way around with a certain frequecy.

My idea was to realize that with an L90 valve section where the spool goes from one max. stroke to the other.

Is there a possibility to automate this function so for example after activation on the display the COUT goes into max. positive direction and afterwards into max. negative direction and back again? The speed I could adjust via slopes.

I guess this task can be solved with some math channels but do we maybe have a different solution with other channels?

Thanks for your support and regards
