SM150 wassergekuhlt Introduction 1 This 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. SINAMICS SM150 6SL3845 G20 F03 F72 F79 F76 Reference Manual Rev.201902141436 SM150 wassergekuhlt 7 Introduction 8 SINAMICS SM150 6SL3845 G20 F03 F72 F79 F76 Reference Manual Rev.201902141436 SM150 wassergekuhlt 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. SINAMICS SM150 6SL3845 G20 F03 F72 F79 F76 Reference Manual Rev.201902141436 SM150 wassergekuhlt 9 General scope of services 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. 10 SINAMICS SM150 6SL3845 G20 F03 F72 F79 F76 Reference Manual Rev.201902141436 SM150 wassergekuhlt General scope of services 2.1 Routine test 2.1 Routine test During production, the drive is subject to an internal routine test.

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.
