What this drive delivers at the motor shaft
The ATV1200A17156666 is a medium-voltage VFD rated for 1434 kW motor output, drawing 1715 kVA apparent power from a 2970 to 3630 V supply. That's not a derated figure — it's the full continuous rating for an asynchronous motor load, so the drive handles the full pump, fan, or conveyor duty without oversizing the cabinet. The 36-pulse diode rectifier input keeps line-side harmonics low enough that you can skip a separate harmonic filter in most installations — the integrated EMC filter handles the conducted emissions side.
Overload profile and fault handling
Standard overload rating holds 1.2× In for 60 seconds and 1.5× In for 3 seconds; switch to high overload mode and it handles 1.5× In for 60 seconds and 1.85× In for 3 seconds. That extra headroom matters when you're starting a high-inertia load or clearing a downstream fault without tripping the drive. Prospective line short-circuit current rating is 31.5 kA for 150 ms — the drive withstands that fault pulse without internal damage, so upstream breaker coordination can be set to the drive's withstand curve rather than forcing a full-selectivity scheme. Ground fault protection is integrated into the drive itself, not reliant on an external relay. That saves a panel component and reduces wiring.
Physical footprint and installation constraints
The drive ships as a floor-standing enclosure. Standard-efficiency version measures 3960 mm wide × 1500 mm deep × 2740 mm high; the high-efficiency variant is wider at 4260 mm and deeper at 1600 mm. That's a full cabinet row — plan for fork-truck access during installation and a 300 mm clearance behind for the forced-convection airflow path. Cooling air volume is 29,900 m³/h for standard efficiency, 33,200 m³/h for high efficiency. The room ventilation system needs to handle that exhaust heat — don't let the ambient temperature creep above the 0 to 90 % humidity envelope. Operating altitude up to 1000 m is full rating; above that, derate 0.6 % per 100 m up to 2000 m. If the installation is above 2000 m, you need a custom engineering review — the drive's pollution degree 2 rating assumes a controlled environment.
Control wiring and I/O complement
Four software-configurable analogue inputs (0-20 mA / 4-20 mA, 24 V max, 250 Ω impedance) and one analogue output of the same type. Six discrete inputs standard, expandable to ten with an option board. That's enough for basic speed reference, feedback, and run/stop commands without an extra I/O slice. Control supply is 220 V AC at 3 kVA, external. The cooling fan runs on a separate 380 V AC supply — keep those circuits independent so a fan failure doesn't take down the control logic.
Compliance and lifecycle status
CE marked, designed to EN/IEC 60204-11, 60529, 61800-3, 61800-4, and 61800-5-1. Dielectric strength is 20 kV AC between earth and power terminals — that's the insulation coordination for a medium-voltage drive connected directly to a 3.3 kV bus. Lifecycle stage is listed as current — meaning the manufacturer still supports it as an active catalogue item.
