The Schneider ATV9A0C80Q6 is a modular Altivar Process ATV900 drive rated for 800 kW at 690 V normal duty and 630 kW at 690 V heavy duty. That places it on the high end of the ATV900 frame — meant for large induction or synchronous motors in pump, fan, compressor, or conveyor applications where you need the full 690 V line. It ships as a kit: control unit, mechanical mounting kit, power connection set, fuses, a 200 kW power module, and one front cover. Modular construction means you can swap power modules without pulling the whole cabinet, which is a relief if you're stocking spares for multiple frame sizes.
Motor power is your first check: 800 kW normal duty (typically for variable torque loads like pumps and fans) and 630 kW heavy duty (constant torque like conveyors or extruders). The switching frequency is adjustable from 2 to 4.9 kHz — lower settings reduce losses and allow higher current; higher settings quiet the motor but require derating. Plan for the derating curve if you push past 4 kHz. The integrated EMC filter meets IEC 61800-3 category C3 with 300 m cable length. In a North American panel, this usually satisfies the conducted emissions requirement without an add-on filter — saves a DIN rail slot and a wiring step. Pollution degree 2 is standard for a protected cabinet environment. Safe torque off (STO) is built in at SIL 3. That means you can wire the safety circuit directly to the drive without a separate safety relay for the torque-off function — reduces component count and wiring when you're doing a PL e or SIL 3 safety system. Communication flexibility: Slot A accepts Profibus DP V1, PROFINET, DeviceNet, EtherCAT, CANopen (two variants), and more. Slot B and C handle I/O and encoder extension. The base unit includes one Modbus serial port (2-wire RS-485, RTU) and one Ethernet port for Modbus TCP — so you can talk to the PLC immediately while the fieldbus card is on order.
