The ATV980C45T4X1 is a regenerative variable speed drive from the Altivar Process ATV900 family, built as a compact floor-standing enclosure with IP23 protection. It's rated for 480 V three-phase supply, delivering regenerative capability for asynchronous and synchronous motors — meaning it can return braking energy to the line, not just dump it as heat. The CE marking and compliance with IEC 60204-1, IEC 61800-5-1, IEC 61800-3, and IEC 61800-2 confirm it meets European machinery and drive standards out of the box.
Supply frequency is 50...60 Hz ±5%, so it works on either 50 or 60 Hz mains without adjustment. The 480 V ±10% supply voltage covers common 400 V and 480 V grids. Operating temperature range is 0...40 °C without derating, and 40...50 °C with derating — plan for that if your panel runs hot. Altitude derating starts at 1000 m: 1 % per 100 m up to 2000 m, then continues with the same rate for TT, TN, and IT earthing systems up to 4800 m. Forced convection cooling means the enclosure needs clearance for airflow; vertical mounting ±10° is required.
Built-in equipment and connectivity
The ATV980C45T4X1 ships as a complete package: enclosure (Spacial SF), graphical operating panel in the door, frequency inverter, main switch, line choke, terminal blocks for main supply and motor, and a dv/dt filter choke. Communication is handled via Modbus TCP, EtherNet/IP, and Modbus serial — three protocols on board, no extra option card needed for basic networking.
Rated for shock resistance of 4 gn for 11 ms (IEC 60068-2-27, class 3M2) and vibration resistance of 1.5 mm peak-to-peak at 3...20 Hz and 0.6 gn at 10...200 Hz (IEC 60068-2-6, class 3M3). Humidity range is 5...95 % without condensation (IEC 60068-2-3). Environmental classes include chemical pollution resistance 3C3, dust pollution resistance 3S3, and humidity resistance 3K3 per IEC 60721-3-3. Storage temperature spans -25 to 70 °C.
EMC and insulation
EMC immunity is specified at level 3 for electrostatic discharge (IEC 61000-4-2), radiated RF (IEC 61000-4-3), surge (IEC 61000-4-5), and conducted RF (IEC 61000-4-6), and level 4 for fast transients (IEC 61000-4-4). Insulation tested at 1 MOhm, 500 V DC for 1 minute to earth.
