The ATV980C31Q4X1 is a regenerative variable speed drive from the Altivar Process ATV900 family, built for asynchronous and synchronous motor control. It ships as a floor-standing compact enclosure with IP23 protection, rated for 380...415 V three-phase supply at 50/60 Hz. The unit includes the Spacial SF enclosure, graphical operating panel, main switch, line choke, dv/dt filter choke, and terminal blocks for mains and motor — essentially a pre-integrated drive cabinet ready for power wiring.
The headline power range is 315 to 250 kW — that spread reflects the regenerative topology: the drive can handle a 315 kW motor in motoring mode, but the regenerative rating caps at 250 kW continuous. For a buyer sizing this into a BOM, the number that governs the real-world fit is the supply voltage band: 380...415 V -10...6 %. That is a 342 V minimum to 440 V maximum window. If your plant runs a 400 V nominal distribution with typical 5 % sag, you are inside the window. If you are on a 480 V system, this is not the variant. Total harmonic current distortion (THDI) is listed at <5 % at full load, conforming to IEEE 519. That is a genuine line-side spec — no external harmonic filter needed for most utility compliance checks. The drive already carries a line choke in the enclosure. Cooling is forced convection, so the enclosure intake and exhaust paths need clearance. The operating position is vertical ±10°, and derating starts above 40 °C ambient — 40...50 °C with a derating factor applied. No derating below 0 °C only if the optional enclosure heater is fitted.
Integration notes
Communication is handled via the embedded Modbus serial port plus EtherNet/IP and Modbus TCP on the same physical connector. No separate option card required for those protocols. Overvoltage category III on the supply side means it is rated for fixed-installation distribution-level transients — consistent with a floor-standing drive fed from a panel MCCB. Environmental resistance is specified to 3C3 (chemical), 3S3 (dust), and 3K3 (humidity) per IEC 60721-3-3. That puts it in the same class as drives intended for industrial halls with moderate airborne contaminants — not clean-room, not outdoor. The IP23 enclosure keeps out solid objects >12 mm and water spray up to 60° from vertical, but it is not hose-down rated. Altitude derating starts at 1000 m: 1 % current derating per 100 m up to 2000 m, then continues at the same rate through 4800 m for TT, TN, and IT earthing systems. For a installation at 1500 m, expect roughly 5 % current reduction from the nameplate rating.
