What this drive is wired for
The ATV1200A5706060 is a medium-voltage drive from the Altivar 1200 family, rated for 477 kW motor output at a supply voltage of 2970…3630 V. The 30-pulse diode rectifier front end keeps line-side harmonics low without an external filter — a common spec for sites with weak utility ties or harmonic limits. Apparent power is 570 kVA, and the line current at rated load is 65 A. The overload profile covers both standard and high-overload duty: 1.2 In for 60 s or 1.5 In for 3 s under standard, and 1.5 In for 60 s or 1.85 In for 3 s under high-overload. That means it handles a pump/fan starting curve or a crusher impact cycle without tripping, as long as the overload class matches the application. Output voltage is limited to the supply voltage, so the motor sees full line voltage. The drive is intended for both synchronous and asynchronous motors, which covers the majority of MV induction and PM machines.
Physical footprint and cooling demand
This is a floor-standing enclosure. Standard-efficiency dimensions are 2860 mm wide × 2590 mm high × 1400 mm deep; the high-efficiency variant adds 300 mm to the width and 150 mm to the height and depth. The cooling air volume is 16,600 m³/h for standard efficiency, or 19,900 m³/h for high efficiency — plan the room ventilation accordingly. Noise level is 80 dB, which means hearing protection zones around the drive during operation. Forced convection cooling with separate air flows keeps the power section and control compartment thermally isolated.
Control wiring and I/O count
The drive has 4 software-configurable analogue inputs (0…20 mA / 4…20 mA, 250 Ω impedance) and 1 analogue output of the same type. Discrete inputs number 6 as standard, expandable to 10 with an optional card. Electrical isolation between power and control circuits is provided, which simplifies grounding in mixed-voltage panels. A 220 V AC, 3 kVA external supply powers the control section; the cooling fan runs off a separate 380 V AC supply. An optional 220 V AC/DC control supply is available. The integrated EMC filter meets EN/IEC 61800-3 requirements for the drive's intended environment.
Standards, protection, and compliance
CE marked, with compliance to EN/IEC 60204-11, EN/IEC 60529, EN/IEC 61800-3, EN/IEC 61800-4, and EN/IEC 61800-5-1. Overvoltage category II and pollution degree 2 per EN/IEC 61800-5-1. Dielectric strength is 20 kV AC between earth and power terminals — a solid margin for 3.3 kV class systems. Ground fault protection is integral to the drive. Prospective short-circuit current withstand is 31.5 kA for 150 ms, which covers most MV distribution points. Operating altitude is 1000…2000 m with a 0.6 % derating per 100 m above 1000 m.
