Note:
An acceptance test of static excitation units according to options
F03
,
F73
and
F77
is only possible together with the converter
which must be ordered simultaneously.
In general, a high voltage test of the converter is already
performed during the type test. When the test is repeated as
part of option
F77
, the test voltage is reduced to 80 % (accord-
ing to DIN EN 61800-5-1/VDE 0160 T105 (IEC 61800-5-1)).
Excitation units are only accepted as part of option
F97
when
this option is simultaneously selected for the converter and
excitation unit and is generally performed at another location
and at another time.
F28, F72, F76
Converter acceptance tests without the customer present
The acceptance scope of these options corresponds to that of
options
F29, F73
or
F77
, however, without the customer being
present.

Customer-specific system acceptance tests (on request)
For a system acceptance test, transformer (if technically required), converter, cooling system (if technically required) and motor should be
set up and commissioned. Converter, cooling system and transformer are mounted directly next to each other, but separately from the
motor.
Only already pre-tested components (together with a test certificate) are subject to a system test.
The tests that can be performed in the System Test Center are listed in the following. For each system acceptance test, the actual test
scope must first be coordinated with the Siemens contact person.
Temperature-rise test
Full load test run or partial load test run of the motor in converter operation until the temperature reaches its steady-state level.
The operating point should be preferably selected where the highest temperature increases is expected (
M
N
,
n
N
). The resistance method
is the basis for determining the temperature rise. During the temperature-rise test, in addition to the motor temperatures, the electrical
operating parameters of the complete drive system are also continuously recorded.
Load tests
• Load points at four different operating points
• The system efficiency is determined at the defined load points
• Line-side harmonics analysis
Additional tests
• High-voltage insulation test:
The converter and motor have already been tested as part of the routine tests performed during production. Re-testing the converter is
time-consuming and is not recommended. It can only be performed as part of a test that is separately performed for options
F73/F77
.
• Converter function test:
The fault and alarm functions are checked using defined simulation routines (e.g. overtemperature trip, EMERGENCY-STOP, overcurrent,
overspeed, undervoltage)
• 120 % overspeed test
• Noise measurement (motor fed from the converter without load)
• Vibration measurement (motor fed from the converter without load)
• Visual inspection (converter and motor and where relevant, transformer)
