Mechanical ¨ Reduced costs of transmission components — Low starting torque — Starting torque adjustable to requirement ¨ Reduced maintenance costs — Low starting torque reduces belt slip ¨ Lower repair costs — Fatigue effects reduced (Star/delta, transformer and single-phase starting cause high torque peaks) ¨ Machine protection — Electronic overload trip (with OPTION I1) Electrical ¨ Low starting current — Advantageous compared with star/delta ¨ Low maintenance costs — Low-loading of contactor contacts with zero-current switching ¨ Only two voltage ranges — 3AC 110…500 ±10 % V — 3AC 220…690 ±10 % V
