Startup Trace - Siemens SINAMICS S120 Commissioning Manual

Sequence of multiple trace
1. A multiple trace is started just like a conventional single trace using parameter p4700.
2. The multiple trace component saves the measurement result after the trigger condition
3. The single trace that has actually been completed is now automatically restarted from the
4. All additional cycles are automatically executed in the same way. The currently running
Trace status
The status of the particular single trace can be read via parameter r4705. You cannot stop a
multiple trace and then continue it. A multiple trace can only be canceled and restarted.
Time assignment
An individual trace can be assigned with respect to time using two parameters. The two
parameters show the time at which the trigger condition was fulfilled:
● r4797 shows the trigger instant for trace recorder 0
● r4798 shows the trigger instant for trace recorder 1

Startup trace

A start up trace basically consists of a conventional single trace with all of its configuration
options (number of channels, sampling depth, recording cycle, etc. ). With the appropriate
configuration, a startup trace is automatically active after a drive restarts.
Configure startup trace
1. Set the required trace configuration (e.g.: p4710, p4711, ...).
2. Activate the startup trace using the parameter setting p4703[bit 0] = 1.

multiple trace component. In this case, the same trace configuration (trigger condition,
recording cycle, etc. ) is used as before. The trace buffer of the previous single trace is
emptied in the process.
cycle is displayed in parameter r4841 – including its subsequent deadtime (starting
with 1).
After the drive restarts, a new trace is immediately started (without any additional user
action).
