5 5.3 5.3.3 Multi-axis controllers Rated data Overcurrent operation 5.3.3 Overcurrent operation The controllers are designed for two overcurrent modes: ƒ 5-s-cycle c – 0.5 s load period with peak current – 4.5 s recovery time with limited current ƒ 3-min cycle d – 1 min load period with peak current – 2 min recovery time with limited current A load period must be followed by a recovery time. During the recovery time the current must not exceed the value given. The values given refer to the rated output current I aN8 .
