Introduction 1This document describes the preconditions when testing drives. The fulfillment of these preconditions is the basis for achieving the smoothest possible testing process and maximum possible customer satisfaction.

The following drive tests are described:

● Routine tests

● Tests that are offered as standard

Note

If the scope of testing and inspection cannot fulfill all customer requirements, please consult your Siemens sales advisor at head office.


Introduction



General scope of services 2A 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 offeredUnless 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 acceptanceA 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.


Components provided by customerComponents 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 acceptanceAll customer acceptance tests in the test fields for drives are performed as part of the manufacturing process.

NoteLimited 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.

NoteTest 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.

NoteTests 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.

3.2.25 Bypass

FundamentalsThe appropriate bypass contactor must energize 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 procedureThe test is carried out with reduced power across an inductive load.

1. The drive is switched on.

2. A fiber-optic cable connector of a gating module is withdrawn for each phase.The corresponding bypass contactor of the failed power semiconductor module energizes.An alarm message is displayed on the test station computer.

3. The fiber-optic cable connector of an additional gating module is withdrawn.The inverter is shut down.A fault message is displayed on the test station computer.


3.2.26 Load test without motor

Fundamentals The internal measuring device of the drive is checked for an inductive load. The calibrated measuring equipment is used as reference.

When testing a version with 60 Hz input transformer on a 50 Hz line supply, the power is reduced.

Test procedure1. The drive is switched on in a test mode.

2. The inverter is enabled.

3. The rms values of voltage, current, apparent and active power are measured at the input and output of the drive.

ResultThe test is passed if the values displayed on the test station computer match the reference values with a tolerance of ±5 %.

3.2.27 Display devices in the cabinet door

Fundamentals Three display devices are mounted in the cabinet door of the control section. During the "Load test without motor", a check is made whether the displayed values correspond to the measured values of the calibrated measuring equipment.




Test procedure1. The "Load test without motor" is carried out

The following values are displayed:

– Output current from 0 to +100 %

– Output voltage 0 to +100 %

– Speed in the range from -100 % up to +100 %

ResultThe test is passed if the display device values match the reference values with a tolerance of ±5 %.

3.5 Additional optional tests

3.5.1 Temperature-rise test

FundamentalsUsing the temperature-rise test, the temperatures under load at defined measuring points are determined.

Test procedure1. The drive is operated for eight hours in the test mode the same as in the "Load test without

motor".

2. The temperature is measured after eight hours at the following measuring points:

– Air discharge 1 at the transformer unit: Fan -E31

– Air discharge 2 at the cell unit: Fan -E32

– Transformer core: At the upper side of the core close to terminals T1:H1, T1:H2, T1:H3

– Reactor core: At the upper side and center of the core (only for option L09)

– Ambient temperature

ResultThe measured values are documented together with the "Functional test plan".

3.5.2 Temperature behavior of the infeed transformer

Fundamentals In addition to the temperature-rise test, the temperature of each of the windings of the infeed transformer is measured before and after the temperature-rise test. This test can only be ordered in conjunction with a temperature rise test.

Test procedure1. The temperatures of the individual windings are determined before the temperature rise test.

2. The drive is operated for eight hours in the test mode the same as in the "Load test without motor".

3. The temperatures of the individual windings are determined after the temperature rise test.

Tests3.5 Additional optional tests



ResultThe maximum temperature rise of the individual windings must not exceed the appropriate limit values. The measured values are documented together with the "Functional test plan".

3.5.3 Power factor measurement

Fundamentals The power factor is measured at different operating points.

Test procedure1. The drive is operated in the test mode the same as in the "Load test without motor".

2. The power factor is measured at the input and output at 50 %, 75 % and 100 % load.

ResultThe measured values are documented in the "Functional test plan".

3.5.4 Efficiency and loss measurement

Fundamentals Efficiency and losses are measured at various operating points.

Test procedure1. The drive is operated for 20 minutes each in the test mode, the same as in the "Load test

without motor".

2. Efficiency and losses are measured at two minute intervals at the input and output for 50 %, 75 % and 100 % load.

ResultThe measured values are documented in the "Functional test plan".

3.5.5 Harmonics

Fundamentals The effects of the drive on the supply grid/line supply are determined by recording the harmonics.



Test procedure1. The drive is operated in the test mode the same as in the "Load test without motor".

2. The first 50 harmonics are measured for each phase, and the average of the harmonics calculated on a proportional basis.

ResultThe test is passed if the corresponding average limit values are not exceeded.

3.5.6 Noise measurement without load

Fundamentals The noise measurement is conducted in operation without load, but with the main fans running according to EN ISO 3744.


2. The measuring points defined are documented in the report and evaluated.

ResultThe results of the noise measurement are separately recorded and documented together with the "Functional test plan".
