Combined tests
For newly developed systems the
customer's request, the frequency converter
is tested combination with motor the
works verify its performance and that it
conforms the design data.
Large units are tested «back-to-back»
(see picture above), i.MEGADRIVE-LCI under test
Back-to-back testing of

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.
Routine testing a
frequency converter. Routine tests and functional tests
form integral part the scope supply
of MEGADRIVE system.
Routine tests
Every component sub-system drive
is tested part the normal production
process. Where additional
tests such load tests, combined tests or
special tests are considered necessary,
they should agreed early possible.
Every component drive subjected
to thorough testing verify that quality
standards and customer requirements are
fully met.e. one converter/motor
combination drives similar combination in
a generation mode. They are carried out accordance
with international standards (e. ABB has adequate
facilities perform all these tests.
Load tests
Major components,
sub-systems the
complete drive are
tested load to
verify power or
current output at
rated and overload
operating points
under defined
cooling conditions.
