Description
Two current foldback algorithms run in parallel in the drive: the drive foldback algorithm and the motor foldback
algorithm. Each algorithm uses different sets of parameters.
Each algorithm has its own foldback current limit, IL.DIFOLD and IL.MIFOLD. The overall foldback current limit
is the minimum of the two at any given moment.
IL.IFOLD = min (IL.DIFOLD, IL.MIFOLD).
IL.DIFOLD is an artificial current, which can be higher or lower than the drive or motor peak current. When
IL.IFOLD becomes lower than the existing current limit (such as IL.LIMITP), it becomes the active current limit.
