Basic Programming 5 - 23 Stall Prevention L3-04 Stall Prevention During Deceleration SelectionThe stall prevention during deceleration function adjusts the deceleration time in order to prevent OV fault trips duringdeceleration. If L3-04=0, stall prevention is disabled, and if the load is large and the deceleration time short enough, the Drivemay fault and stop.If L3-04=1, the standard stall prevention function is enabled. If, during deceleration, the DC Bus voltage exceeds the stallprevention level (see table below), the Drive will discontinue decelerating and maintain speed. Once the DC Bus voltage hasdropped below the stall prevention level, deceleration will continue.
