The ATV1200A79001010 is a medium-voltage drive, not a standard 480 V unit — supply voltage limits are 2970 to 3630 V. Motor power rating is 6604 kW, with apparent power 7900 kVA. This drives large asynchronous motors in heavy industrial applications like pumps, fans, compressors, and conveyors. The 48-pulse diode rectifier front end keeps input harmonics low enough to meet IEEE 519 without external filters — a real advantage for installations near sensitive equipment or utility boundary limits. Overload capability: 1.2 × rated current for 60 s under standard overload, or 1.5 × for 60 s under high overload duty. The 1.85 × for 3 s under high overload handles short-duration peak loads without tripping.
Floor-standing enclosure — physical integration constraints
Dimensions are 1700 mm depth × 9370 mm width × 3040 mm height. This is a floor-standing enclosure requiring a dedicated concrete pad and overhead clearance for maintenance access. Separate air flows for power section and control compartment — forced convection cooling moves 110,000 m³/h of air. The ventilation system must be ducted to outside or to a conditioned space; ambient temperature and dust loading in the room directly affect drive reliability. Operating position is vertical ±10 degrees. The enclosure color is grey RAL 7032.
Power cell topology and internal composition
The drive comprises 24 power cells, a phase-shifting transformer, medium-voltage arrestors, cooling fans, and a human-machine interface. Two plinths support the enclosure. Cell-based architecture means a single failed cell can be bypassed or replaced without taking the whole drive offline — the remaining cells continue running the motor at reduced capacity. This is standard for multi-level MV drives. Dielectric strength is 28 kV AC between earth and power terminals. Electrical isolation between power and control circuits protects the low-voltage control electronics from MV transients.
Control wiring and I/O complement
Four software-configurable analogue inputs, 0–20 mA or 4–20 mA, 24 V max, 250 Ω impedance. One analogue output, same current range and impedance. Six discrete inputs standard, expandable to ten optional. External control supply is 220 V AC, 3 kVA; an optional 220 V AC/DC supply is available. Cooling fan supply is 380 V AC. Power connections are M10 bar-type terminals, clamping capacity 6 × 40 mm² for phases /R, /S, L3/T, entry from top or bottom.
CE marked. Standards compliance includes EN/IEC 60204-11 (electrical equipment of machines), EN/IEC 60529 (IP enclosure), EN/IEC 61800-3 (EMC for drives), EN/IEC 61800-4 (drive specifications), and EN/IEC 61800-5-1 (electrical safety). Pollution degree 2 per EN/IEC 61800-5-1. Overvoltage category II. Operating altitude up to 1000 m standard, with derating of 0.6 % per 100 m from 1000 to 2000 m. Relative humidity 0–90 % standard, 0–95 % optional. Vibration resistance 4.9 m/s² at 10–50 Hz. Noise level 80 dB — hearing protection required within the enclosure perimeter. Prospective line short-circuit current 31.5 kA for 150 ms. Ground fault protection integrated in the drive.
