10.6 Soft braking

For applications with high inertia and/or a variable load, the Digistart IS can be configured for soft braking.
In this application the Digistart IS is employed with forward run and braking contactors. When the Digistart IS receives a start signal

(pushbutton S1), it closes the forward run contactor (KM1) and controls the motor according to the programmed primary motor

settings.
When the Digistart IS receives a stop signal (pushbutton S2), it opens the forward run contactor (KM1) and closes the braking

contactor (KM2) after a delay of approximately 2-3 seconds (KT1). KA3 is also closed to activate the secondary motor settings,

which should be user programmed for the desired stopping performance characteristics.
When motor speed approaches zero, the zero speed detector (A2) stops the soft starter and opens the braking contactor (KM2).
