The ATV9A0C11R4: The normal-duty 110 kW rating is the headline number for centrifugal pumps and fans where overload is minimal. The heavy-duty 90 kW rating governs constant-torque loads like conveyors or extruders — that 183 A line current at 440 V normal duty drops to 155 A for heavy duty, so sizing the input wiring and fusing for the heavy-duty current ensures the drive can deliver its rated torque without nuisance tripping. The integrated EMC filter is rated for 300 m of motor cable per IEC 61800-3 category C3 — enough for most industrial installations without an external filter. The IP00 enclosure means the drive lives inside a cabinet rated IP21 or IP54.
Integration Notes
The modular version ships as a kit: power module, control unit, mechanical mounting kit, and power connection set of fuses. The control block carries two RJ45 for Ethernet IP/Modbus TCP and one RJ45 for Modbus serial (RS-485, 2-wire, RTU, 4.8 to 38.4 kbit/s). Supply voltages: 24 V DC (19...30 V) for digital inputs, a separate 24 V DC (21...27 V) for digital inputs and STO, and a 10.5 V DC reference for a 1 to 10 kOhm potentiometer. The line-side connection uses screw terminals; motor connection uses M10 bars.
