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 factory offers adapted test systems adapted to address such 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 tests ordered includes all activities, equipment, materials and expendables required.

Additional activities, services and provisions - for example, the use of third-party converters - must be coordinated well in advance.

The deadline and testing period stated, and the quoted cost, can be met only if all the test and inspection procedures 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 system test facility.

Test equipmentSiemens ensures the availability of the equipment required for the agreed tests and inspections, including test couplings for load runs.

Customer couplings, coupling dummies and coupling jigs for non-cylindrical shaft extensions are excluded.


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 factory has no access to components, which are not part of the scope of supply of PD LD. 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.

General scope of services
