Trace function for optimizing the drive

Description
The trace function is used for converter diagnostics and helps to optimize the behavior of the
drive. Start the function in the navigation bar using "... Control_Unit/Commissioning/Device
trace".
In two settings that are independent of one another, using
signals each. Each signal that you interconnect is active as standard
You can start a measurement as often as required; the results are temporarily stored (until
you exit STARTER) under the "Measurements" tab, together with the date and time. When
terminating STARTER or under the "Measurements" tab, you can save the measurement
results in the *.trc format.
If you require more than two settings for your measurements, you can either save the
individual traces in the project or export them in the *.clg format – and if necessary, load or
import.
Recording
Recording is performed in a CU-dependent basic clock cycle. The maximum recording
duration depends on the number of recorded signals and the trace clock cycle.
You can extend the recording duration by increasing the trace clock cycle by multiplying with
an integer factor and then accepting the displayed maximum duration by
you can also specify the measurement period and then you can calculate the trace clock
cycle of STARTER using
Recording individual bits for bit parameters
You can record individual bits of a parameter (e.g. r0722) by allocating the relevant bit using
"bit track" (
Mathematical function
Using the mathematical function (
between the speed setpoint and the speed actual value.
Note
If you use the "record individual bits" or "mathematical functions" option, then this is
displayed under signal No. 9.
