General scope of services 2
A variable-speed drive can include the following components:
● Induction motor, synchronous motor or PEM motor with or without speed encoder
● SINAMICS drives
● Drive transformer
● Cooling unit for water-cooled drives
● Small PLCs with drive functionality.
The Nuremberg Vogelweiherstrasse factory offers test equipment adapted to these types of
systems.
Note
Contact your sales person if additional components must be taken into account for your
particular project.
Scope of services offered
Unless otherwise stated in the quotation, the scope of services includes all activities,
equipment, materials and expendables required to perform the specified tests. The deadline
and testing period stated, and the quoted cost, can be met only if all the test and inspection
procedures to be performed are clarified in detail in advance. Due to the high capacity utilization
of the associated equipment, it might not be possible to carry out individual inspections and
tests that are requested late if the planned test is already in progress.
If you have received specific requirements from your customer, please send these as soon as
possible – with the necessary key data – to the Nuremberg Vogelweiherstrasse factory.
Sequence of a customer acceptance
A customer acceptance test is generally executed in the sequence:
1. Installation and commissioning of the components before the customer arrives.
2. Kickoff with presentation of the test schedule and discussion of individual steps in the
acceptance test workflow.
3. Execution of the tests according to the test schedule
4. Discussion of the test results
5. Preparation of test documentation for the customer.
The test documentation is created before or after the customer leaves depending on the
scope of testing and the time schedule.

Reference Manual Rev.201902141436 SM150 wassergekühlt 9
Components provided by customer
Components provided by the customer must be available in plenty of time so that tests can be
carried out on time. The Nuremberg Vogelweiherstrasse factory has no access to components
that are not within the PD LD scope of supply. This also applies to components ordered from
other Siemens' Groups. The technical data for these components is required at the latest eight
weeks before the start of the acceptance test, e.g.:
● Dimensions
● Weights
● Energy Requirement
● Interfaces
Location of the customer acceptance
All customer acceptance tests in the test fields for drives are performed as part of the
manufacturing process.
Note
Limited number of persons in the test field
For safety reasons, the number of persons in the test field is limited. In addition to the regional
sales partner, only two persons from the customer are permitted in the test field at the same
time.
Note
Test without load motors or multipulse infeeds via transformers in the test field
Some tests are simulated or performed in test mode with limited rated data.
Note
Tests with the customer's own cooling units or excitation equipment
If the customer's own cooling units or excitation equipment are to be tested, a system test can
be ordered with option F97.

2.2 Visual inspection
The visual inspection is performed to ensure that the equipment complies with the order
specifications. The tests are carried out with the drive in a no-voltage condition.
The visual inspection together with the customer – or with the company accepting the
equipment – is carried out with the drive installed and labeled. Each test step is documented in
the acceptance report with the specific results of the step.
The visual inspection is part of the function test (F72, F73).

2.3 Function tests
The drive functions are tested according to IEC 61800-5-1. In addition, excerpts from additional
standards apply, which are listed in the relevant chapters as well as internal Siemens directives
within the scope of quality assurance.
The function tests are performed and documented in the Siemens test field by internal test field
personnel. For the function test, the drive is in the test mode with restricted monitoring functions.

values with a tolerance of ±5 %.
3.2.9 Overvoltage monitoring in the DC link
Fundamentals
Fluctuations in the power supply can result in short-term changes to the DC link voltage.
The overvoltage monitoring senses the actual value of the DC link voltage, and switches off the
drive at a defined rated voltage.
Test procedure
1. The auxiliary voltage is present.
2. The DC link is charged up to 100 %.
3. The drive is operated with a load current ILoad = 50 ±5 A.

Result
The test is passed if the value calculated is 123 % of the nominal voltage of the DC link.
3.2.10 Failure of a power semiconductor module
Fundamentals
The power section must shut down if a power semiconductor module fails. The failure is
simulated by withdrawing the fiber-optic cable connector from the gating module of a power
semiconductor module. This interrupts the control.
Test procedure

3.3.3 Measuring the coolant conductivity and coolant temperature
Fundamentals
Tests are performed in accordance with IEC 60146-1-1.
Sensors in the drive coolant circuit acquire the coolant temperature in the supply line and the
coolant conductivity. The measured values from these sensors are compared with the
measured values of the calibrated cooling unit.
The coolant flow is set at the cooling unit to the calculated flow.
Test procedure
1. The cooling unit is switched on. The auxiliary voltage is present.
2. The calculated flow is checked. It is permissible that the flow deviates by ±5 % from the
calculated value.

3.4 Insulation test
3.4.1 High-voltage test
Fundamentals
The test is carried out according to the following standards:
● IEC 61800-5-1
● IEC 62103
● For marine applications, additional requirements from the marine classification societies
may apply.
The high-voltage test verifies the voltage strength (test voltage) for overvoltage conditions
specified in the standard.
Test equipment
A calibrated test instrument is used for the test.
Test procedure
1. The circuits to be tested are separately short-circuited corresponding to the individual
voltage levels.
– Power circuit/circuits
– Various auxiliary circuits
2. The circuits that are presently not connected to the test instrument are connected to ground
potential.
3. The test voltage is adjusted for each circuit corresponding to the insulation test report.
4. The circuits are tested with respect to one another and with respect to the PE protective
conductor at the electrical cabinet.
The test duration is 1 s, for marine applications, 60 s.
5. The test is repeated with 80% test voltage.
Result
The test is passed if the test instrument is not switched off (tripped) during the test as a result
of flashover.
