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"Instruction list" This is a low-level language and resembles assembly.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 currentThe effective value of the peak current. When IL.IFOLD becomes lower than the existing current limit (such as IL.LIMITP ), it becomes the active current limit.
