Reduced run function

The Reduced run function is available for parallel-connected inverters. The function
makes it possible to continue the operation with limited current if an inverter
module(s) is out of order. If one of the modules is broken, it must be removed.
Parameter change is needed to continue the run with reduced current
CONFIG USER). For instructions on how to remove and reconnect an inverter
module, see the appropriate drive hardware manual.
