Back-to-back testing of

drives ABB's motor works
at Birr Switzerland. ABB has adequate
facilities perform all these tests.
Large units are tested «back-to-back»
(see picture above), i. Where additional
tests such load tests, combined tests or
special tests are considered necessary,
they should agreed early possible. Routine tests and functional tests
form integral part the scope supply

If desired these tests
can also verify the

Special and performance tests
At the customer's request, special tests the
complete drive system can carried out to
check the noise level, short-circuit capability,
electromagnetic compatibility (EMC) etc.e.g
