SINAMICS G120 Control Units CU240S, Edition 05/2007
Description: Performs calculations necessary for optimized motor operation.
After completion of calculation, P3900 and P0010 (parameter groups for commissioning) are automatically reset to
their original value 0.
Values: 0: No quick commissioning
1: End quick commissioning with factory reset
2: End quick commissioning
3: End quick commissioning only for motor data
10: Accept safety changes (only on safety CU)
11: Cancel safety changes (only on safety CU)
Dependency: Changeable only when P0010 = 1 (quick commissioning).
Or for safety commissioning P0010 = 95.
Note: P3900 = 1 :
When setting 1 is selected, only the parameter settings carried out via the commissioning menu "Quick commis-
sioning", are retained; all other parameter changes, including the I/O settings, are lost.
Motor calculations are also performed.
P3900 = 2 :
When setting 2 is selected, only those parameters, which depend on the parameters in the commissioning menu
"Quick commissioning" (P0010 = 1) are calculated.
The I/O settings are also reset to default and the motor calculations performed.
P3900 = 3 :
When setting 3 is selected, only the motor and controller calculations are performed.
Exiting quick commissioning with this setting saves time (for example, if only motor rating plate data have been
changed).
Calculates a variety of motor parameters, overwriting previous values. These include P0344 (motor weight), P0350
(demagnetization time), P2000 (reference frequency), P2002 (reference current).
P3900 = 10 (only on safety CU)
Finishes the safety commissioning by accepting the safety changes.
The safety commissioning including safety dynamization will take about 5 s.
P3900 = 11 (only on safety CU)
Finishes the safety commissioning by discarding the safety changes. The safety settings that were active before the
safety commissioning are reloaded.
The safety commissioning including safety dynamization will take about 5 s.
When transferring parameter p3900, the frequency inverter uses its processor to carry-out internal calculations.
Communications - both via USS as well as via the Fieldbus - are interrupted for the time that it takes to make these
calculations. This can result in the following error messages at the connected SIMATIC S7 control (communications
via fieldbus):
• Parameter fault 30
• Drive fault 70
• Drive fault 75
When using STARTER (USS) to commission the drive system, data cannot be entered while these calculations are
being made.
The faults can be acknowledged as soon as the calculations have been completed in the frequency inverter. These
calculations can take up to one minute to complete.
