Semiconductor soft starter 3RW3 Control of a motor with an electromechanical brake An electromechanical brake that is fed from the main voltage (L1/L2/L3) should not be wired directly into the soft starter's output. An electrome- chanical brake should be controlled via a separate contactor (K1 in the fol- lowing wiring diagram): L1 L2 Ue L3 Q1 Us G1 AN U V W K1 BR BR2 M 3 k K1 A1 A2 Fig. 8-26: Motor control with electromechanical brake 8-38 Stand 08/99 >> I>> I>> 1 L2 L3 A2 A1 IN 3RW30 ON BYPASSED 1 T2 T3 13 14 23 24 F
