Motor power and duty ratings that size the BOM
The ATV9B0C40N6: Rated 280 kW at 500 V in normal duty, 220 kW in heavy duty — the heavy-duty figure governs continuous overload capability for conveyors, pumps, and compressors that cycle against a load. Line current at 500 V normal duty is 352 A, dropping to 278 A in heavy duty — this sets the cable cross-section and upstream protection sizing, not the motor nameplate alone. Apparent power of 305 kVA at 500 V normal duty confirms the transformer and switchgear headroom needed upstream.
Safety integration and fieldbus slots
Three option card slots (A, B, C) accept Profibus DP V1, PROFINET, EtherCAT, CANopen, DeviceNet, or digital/analog I/O extension modules — the fieldbus protocol is selected at ordering, not hardwired. Dual RJ45 Ethernet IP/Modbus TCP ports plus a separate RJ45 Modbus serial port allow the drive to sit on both the control network and a commissioning tool simultaneously.
Cabinet integration and environmental limits
Rated IP00 for integration into an IP21 or IP54 cabinet — the drive itself has no enclosure; the panel builder provides the environmental seal and cooling airflow. Integrated EMC filter meets IEC 61800-3 category C3 for 300 m motor cable — this covers most industrial installations without an external filter, though C3 limits conducted emissions to an industrial environment, not residential. Operating altitude limited to 2000 m with derating above 1000 m — a site at 1500 m needs the current derating factor applied before sizing the drive to the motor.
