Reduced run
A “reduced run” function is available for supply/rectifier units consisting of parallel-connected
modules. The function makes it possible to continue operation with limited current even if
one (or more) module is out of service, for example, because of maintenance work.
In principle, reduced run is possible with only one module, but the physical requirements of
operating the motor still apply; for example, the modules remaining in use must be able to
provide enough current.
