Time stamp mode
The mode for the time stamp can be set via parameter p3100.
Setting Explanation
p3100 = 0 Time stamp based on operating hours
p3100 = 1 Time stamp UTC format
p3100 = 2 Time stamp operating hours + 01.01.2000
Additional setting for firmware V4.7 and higher:
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.
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 response required is
the one for versions older than V4.7 then p3100 = 0 should be set.
9.3.15 Simulation mode
Description
Simulation mode 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, simulation mode is reset, and a fault code F07826 is issued.
Communication with a higher-level automation system can be tested using 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.
Simulation mode also allows you test the correct functioning of the power module.
Particularly with devices greater than 150 HP (110 kW) (400 V), you must check that the
power semi-conductor can be activated properly after repairs. This is done by injecting a low
DC voltage as DC link voltage (e.g., 12 V) and then switching on the device and enabling the
pulses.
