Function procedure
1. When pulse inhibit (IMP) by controller inhibit or a fault (LU, OU, ...), BRK−OUT changes
immediately to HIGH.
– The drive is then braked by its mechanical brake.
2. When pulse inhibit is reset (DCTRL−CINH = LOW) before the actual speed has fallen below the
threshold BRK−Nx, BRK−OUT changes immediately to LOW (possible only with incremental
encoder).
– The drive synchronizes itself to the momentary speed and follows its setpoint.
– The drive starts once the threshold was undershot. (
