4 4.3 4.3.6 Single-axis controllers Rated data (devices for 400/500V mains) Overcurrent operation 4.3.6 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 . I [%] aN8 100 t 0 0.5 s 4.5 s 1 min 2 min 9400SSP008 Fig.
