Note that the corresponding short-term his-
togram/short-term monitoring is also reset
on resetting long-term histogram/long-term
monitoring.
On performing the tests MAN, the measur-
ing data of the last measurement as well as
the reference measurements (for d1 and d2)
are stored in the positioner.
On restarting a test MAN, the existing data
are updated by the repeated measurement
data.
In addition, the repeated measurements of
the tests MAN such as drive signal diagram
steady-state and drive signal diagram hys-
teresis can be reset by selecting the
Status
messages
folder (>
Reset
).
Note!
Resetting the measured data does not cause
the reference graphs to be reset:
4
Drive signal diagram steady-state
4
Drive signal diagram hysteresis
4
Reference value for the end position
trend
However, the existing data set is replaced
by the new reference data when the refer-
ence graphs for steady-state and hysteresis
graphs (see section 1.5) are replotted.
The data sets from already existing mea-
surements of steady-state and hysteresis
graphs recorded in both statistical informa-
tion AUTO and tests MAN are reset when
both reference graphs are updated.
Initialization
After an initialization has been successfully
completed, new reference measurements are
automatically plotted and the existing refer-
ence data are overwritten. The new refer-
ence data and the optimized control param-
eters cause the following statistical informa-
tion AUTO and MAN tests to be reset:
4
Drive signal diagram steady-state
(AUTO and MAN tests)
4
Drive signal diagram hysteresis
(AUTO and MAN tests)
4
Setpoint deviation histogram (long-term
and short-term)
4
End position trend
