B.3 Optimize positioning behaviour
The following problems can occur during positioning:
ć the axis stops prematurely on several occasions
ć swinging around the nominal position
ć stability problem, very frequent swinging around the
nominal position
ć overswing
ć underswing.
However, before you begin to optimize the positioning behavĆ
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
appendixĂA).
· 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
andĂ2 the adaptation is not effective.
