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 designed in accord
ance with the regulations (see CMAX system description).
· Make sure that all axis and application data are set cor
rectly.
· Always carry out the identification.
· Then always have several positioning cycles carried out.
This is to guarantee that the adaptation is effective.
If problems still occur, proceed as follows:
1. Observe the positioning behaviour. Use the FCT plugIn in
this case. With the PlugIn you can record and graphically
display setpoint and actual values for path, speed and
acceleration, for
example.
Detailed information on this can be found in the help for the
CMAX PlugIn.
2. Compare the positioning behaviour or the graph compiled
with PlugIn with the following examples.
3. In order to optimize the positioning behaviour, proceed as
described in the table of the corresponding example.
Check first from top to bottom the most
probable causes
and their remedial measures.
