B.3.1

Proceed as follows if the compressed air supply is unstable

If your compressed air supply does not reliably fulfil the
requirements (tolerance of +/− 1 bar in operation), although a
compressed air reservoir has been installed (see chapter
3.2.3), the maximum values for acceleration and delay
ascertained during system identification may, under some
circumstances, not be reached.

This may result e.g. in overswing, if the operating pressure
required for delay is not available.

In order to avoid such overstressing, you can reduce the
dynamics of the system. In order to do this proceed as
follows:

1. Ascertain the lowest static supply pressure available for

positioning in your compressed air network.

2. Lower the supply pressure statically to this level.

3. Now carry out the dynamic identification travel again.

4. When system identification is concluded, increase the

supply pressure again to the value set in the application
data.
