Simulation Operation - Siemens SINAMICS G130 Operating Instructions Manual

Time stamp mode
The mode for the time stamp can be set via parameter p3100.
Setting
p3100 = 0
p3100 = 1
p3100 = 2
Note
Time stamp settings depending on the firmware version
If a project is upgraded from firmware V4.6 to V4.7 then the time stamp settings for the old
project are retained. The times displayed for the error messages do not therefore differ from
those in the old firmware version.
If a new project is created in firmware version V4.7 and above, the factory setting for the
p3100 = 2 and therefore a different time basis for error messages. If the behavior desired is
the one for older versions than V4.7 then p3100 = 0 should be set.

Simulation operation

Description
The simulation function is predominantly used to simulate the drive without a motor being
connected and without a DC link voltage. In this case, it should be noted that the simulation
mode can only be activated under an actual DC link voltage of 40 V. If the voltage lies above
this threshold, the simulation mode is reset, and a fault message F07826 is issued.
Communications with a higher-level automation system can be tested using the simulation
mode. If the drive is also to return actual values, note that it must be switched over to
encoderless operation during simulation mode. This means that large parts of the SINAMICS
software (e.g., software channel, sequence control, communications, technology function,
etc.) can be tested in advance without requiring a motor.
Another application is to test the correct functioning of the power unit. Especially for drive
units with higher power ratings 75 kW (690 V) and 110 kW (400 V), after repairs, it is
necessary to test the gating of the power semiconductors. This is done by injecting a low DC
voltage as DC link voltage (e.g., 12 V). The drive unit is then powered-up and the pulses
enabled.

Additional setting for firmware V4.7 and above.
With this setting the value in p3102 is used as the time stamp for the error
messages. For firmware versions prior to V4.7 the time basis of p2114 was
used with the setting p3100 = 0.
