Well after getting the motor VFD up and running have the last issue hopefully with this . There is a main control valve connected to a pilot valve that then goes to the cylinder that to control the Roboarm up and down .The pilot valve was acting up (or so i assume) as when i hit the main control .cylinder goes up and when i let go of the main control it stops as it should.The problem is when i hit the main control down the cylinder does not stop goes right to the bottom. I have now changed the pilot valve 3 times and it does the same thing .If you reverse the 1/8 lines of the main control it goes down and will stop but cylinder will go right to the top in the up position .I disconnected the lines at the main control to see if that is the issue but the air stops as soon as i let go of the lever
