Encoder diagnostics
7.19.1
A datalogger is available to support troubleshooting; this datalogger can localize errors in the
encoder evaluation.
1. Set parameter p0437.0 = 1 to activate this function.
The datalogger is automatically active as soon as the current controller time is slower
than 125 μs.
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).
iles can only be evaluated by Siemens.

is output while diagnostics data is being actively recorded. Do not switch off
the system during this time.
x = encoder number (x = 1, 2 or 3)
