Trace function

5.3.2.1

Overview

Definition
Using the trace function, you can record the variables of a drive, and then subsequently
evaluate them. Variables are, for example, drive parameters or system and user variables of
a Control Unit. The maximum recording time is limited, for example by the respective
memory size and cycle.
A maximum of 8 individual channels can be recorded (refer to "Number of individual traces").
The recordings are directly saved to the drive, and when required, can be read out and
permanently saved using the engineering system (ES). As a consequence, the trace function
is suitable for monitoring high-speed operations. The recorded values are overwritten when
the trace function is reactivated.
The signals to be recorded, the recording time and the trigger conditions are defined in the
trace configuration.

Trace terminology
Icon Meaning
Settings for the signals to be recorded and the recording conditions
are defined in the trace configuration.
- A trace is being recorded in the device. One recording exists in the
drive for each trace configuration. Each new recording overwrites an
existing recording. A recording in the drive is lost after each switch-
off/switch-on operation, however, the measurement can be perma-
nently saved in the project.
A trace in the drive comprises a trace configuration and optionally,
one recording.
A measurement always comprises one trace configuration and the
associated recording. The recording of a measurement can also be
viewed offline.
