RT processor. To start recording, a trigger event based on the variable can be selected on the
Device trace tab (on a positive edge, a tolerance range or a bit map, for example).
The function generator can be used for test purposes to dynamically generate setpoints with
defined shapes (e.g. rectangle, sine) for various system variables. With the aid of the trace,
for example, the system response can be recorded in order to optimize the controllers.
System trace
You can use the system trace to record and evaluate parameters, system variables, and
program variables from multiple CPUs at the same time. It is essential that the CPUs
communicate via PROFINET. An isochronous connection must exist between the CPUs, and
the PROFINET Sync Master must be a SIMOTION device.
Function generator, mathematical processing and bit tracks are not available for recording with
the system trace.
Measuring function
The measuring function is used for controller optimization.
The SIMOTION measuring functions are used to commission the axis controller without
requiring a user program.
With the SINAMICS measuring function, you can directly inhibit the influence of higher-level
control loops by means of simple parameterization, and analyze the dynamic response of
individual drives. The free measuring function measures and averages several measurement
series with parameterizable noise sources without master control. This measuring function is
suitable for controller settings and for avoiding whirling resonance in magnetic suspension
bearing applications with rotor systems.
Automatic controller setting
The automatic controller setting can be used to configure the speed controller in the drive. For
Dynamic Servo Control (DSC), this is also possible for the position controller.

9.7.2 Task Trace
Application area
The SIMOTION Task Trace supports you when troubleshooting in the SIMOTION multitasking
environment. The SIMOTION Task Trace records the sequence of individual tasks, identifies
user events that you can generate via a program command, and displays these graphically.
