560 kW at 400 V — the heavy-lift VFD for process lines
The ATV9A0C56Q4 is a Schneider Electric Altivar Process ATV900 modular AC drive rated 560 kW at 400 V in normal duty and 450 kW at 400 V in heavy duty — the heavy-duty figure governs continuous motor overload margin on conveyors, pumps, and compressors that see sustained load. Line current at 400 V is 948 A normal duty / 767 A heavy duty, with a prospective line Isc of 50 kA — the input fusing and cable sizing need to handle that fault level upstream.
Safety and standards — STO SIL 3, multi-standard compliance
Safe torque off (STO) is integrated at SIL 3 per IEC 61508 and IEC 13849-1 — the drive can be wired into a safety circuit that removes torque without a separate safety relay, saving panel space on guarding applications. The integrated EMC filter meets IEC 61800-3 category C3 with 300 m of motor cable — suitable for industrial environments where conducted emissions are managed within a controlled installation. CE marked; pollution degree 2 per IEC 61800-5-1; vibration resistance per IEC 60068-2-6 (1.5 mm peak-to-peak at 2-13 Hz, 0.5 gn at 13-200 Hz).
