Trace function
Description
Function overview
7-722
Selected measuring quantities in the drive can be measured correspon-
ding to the specified measuring parameters, using the trace
function and graphically displayed using SimoCom U.
The trace function has the following properties and features:
S
4 trace buffers with up to 2048 measured values
The actual number of possible measured values is dependent on
whether the measuring signal is 24 or 48 bit.
S
Freely–selectable measuring signals
The required signal is selected from a signal selection box.
S
Triggering
– without triggering (the trace starts immediately after START)
– with triggering to an additional trigger signal with signal edge/sig-
nal level/bit pattern triggering and trigger delay/pre–trigger
– trigger is initiated by a change in the bit mask (from SW 5.1)
A trigger is initiated as soon as one of the bits in the bit mask
changes.
S
X/Y scaling: Automatic and selectable
Using the scaling, a sub–range can be specified for the abscissa (x
axis) and ordinate (y axis), so that a section can be displayed.
It is possible to zoom in using an appropriately set scaling factor.
S
Signal measurement via cursor
This means that the signals can be analyzed using the X cursor
(time axis) and/or Y cursor.
S
From SW 5.1, individual bits of a signal can be evaluated.
One or several bits can be selected in the "SimoCom U" in the
"trace" input mask using the "bit masking" button. The bit masking
can be set, independently for each channel and can be recognized
by the units of the associated signal.
Reader's note
The trace function can only be used together with the SimoCom U
parameterizing and start–up tool, i.e. SimoCom U is used to control
the trace function and to display the measured values.
Additional information on the trace function is provided in the online
help for SimoCom U.
