About Tuning a Position Axis -----Into the positioning window is too slow.
See the attachment
Into the positioning window is too slow, I think should adjust the Acceleration Feed Forward.
But in the Acceleration phase, the following error is ok, Deceleration phase is not good。
If i adjust the Acceleration Feed Forward，will Influence the Acceleration phase。
How to modify the parameter to go into the positioning window quickly?

It appears that this axis has some problems with the actuator. In the beginning, there is a delay of almost 0.2 sec before the axis starts moving. Also, at the end the Control Output is not changing very much, but the velocity is oscillating. This makes me suspect the valve may have an overlapped spool, or the valve may be far from the cylinder.
Is the valve far from the cylinder?
Is the valve connected to the cylinder with hard pipe or with hose?
What is the make and part number of the valve?
Is the valve far from the cylinder? no
Is the valve connected to the cylinder with hard pipe or with hose? hose about 500mm
What is the make and part number of the valve？ moog d661
What is the cylinder size? What is the complete valve part number?
