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 fold-
back 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 cur-
rent. When IL.IFOLD becomes lower than the existing current limit (such as IL.LIMITP ), it
becomes the active current limit.
