The ATV6A0C71Q4: Sized for a 710 kW induction motor on 400 V three-phase under normal duty; the heavy-duty rating steps down to 560 kW. Line current of 1192 A ND or 951 A HD sets the upstream breaker and cable class. Internal supply for digital inputs and STO is 24 V DC (21...27 V) at under 200 mA with overload protection; an external 24 V DC (19...30 V) supply feeds the discrete inputs if the internal rail is not used. The integrated EMC filter meets IEC 61800-3 Category C3 for up to 300 m of motor cable, which keeps the cabinet clean on most standard installations. Safe torque off (STO) functional safety is built in at SIL 3 per IEC 61508 – no separate safety module needed for the stop circuit on machinery that requires it.
Cabinet-mounted, forced convection cooled. Pollution degree 2 per IEC 61800-5-1. Shock resistance rated at 7 gn for 11 ms. Relative humidity 5 to 95 % non-condensing. Ambient temperature range is not explicitly listed, but the storage and handling limits are typically wider than operating range – the integrated fan and heatsink assume a clean airflow path.
