B.3 Optimize positioning behaviour
The following problems can occur during positioning:
the axis stops prematurely on several occasions
swinging around the nominal position
stability problem, very frequent swinging around the
nominal position
overswing
underswing.
However, before you begin to optimize the positioning behav
iour of your axis, proceed at first as follows:
· Make sure that the pneumatic axis is built up in
accordance with the regulations (see chapter 3.2 and
appendixA).
· Make sure that all axis and application data are set
correctly.
· Always carry out the static identification and at least one
of the dynamic system identifications.
· Now carry out several positioning cycles. This is to
guarantee that the adaptation is effective.
The adaptation is only effective with position quality
classes 3, 4, 5 and 6; in positioning quality classes 1
and2 the adaptation is not effective.
