Datalogger

A datalogger is available to support troubleshooting; this datalogger can localize errors in the
encoder evaluation.
Commissioning
1. Set parameter p0437.0 = 1 to activate this function.
Principle of operation
The datalogger reads out several internal signals of the encoder evaluation, which serve as
basis for the actual value generation. A change in the fault state serves as trigger for the
recording. Data is recorded a short time before the fault state as well as afterwards.
The diagnostics data is saved on the memory card in the following directories:
/USER/SINAMICS/DATA/SMTRC00.BIN
...
/USER/SINAMICS/DATA/SMTRC07.BIN
/USER/SINAMICS/DATA/SMTRCIDX.TXT
The following information is contained in the index file (SMTRCIDX.TXT):
● Displaying the last written BIN file
● Number of still possible write operations (from 10000 downwards).
Note
BIN files can only be evaluated by Siemens.
