Medium-voltage drive for 752 kW motors
The ATV1200A10206363 is a 752 kW medium-voltage AC drive in the Altivar 1200 family, designed for asynchronous and synchronous motors. Its supply voltage limits are 2970 to 3630 V, putting it squarely in the medium-voltage class for large pumps, compressors, conveyors, and fans in process plants. The 36-pulse diode rectifier input topology reduces line harmonics significantly compared to 6- or 12-pulse designs, often eliminating the need for external harmonic filters and meeting IEEE 519 without additional hardware.
Physical footprint and site planning
This drive ships in a floor-standing enclosure with separate air flows for power and control sections. Standard-efficiency configuration measures 3060 mm wide by 1400 mm deep by 2520 mm high; the high-efficiency variant adds width to 3660 mm and height to 2670 mm, with depth increasing to 1500 mm. Cooling air volume is 13,200 m³/h for standard efficiency and 19,800 m³/h for high efficiency — plan HVAC capacity and ducting accordingly. Noise level is 80 dB, so hearing protection zones and acoustic enclosures may be needed. Operating altitude up to 1000 m is full-rated; above that, derate 0.6 % per 100 m up to 2000 m. The drive must be mounted vertically within ±10 degrees.
Overload capability and protection
Standard overload rating delivers 1.2 × In for 60 seconds and 1.5 × In for 3 seconds. High overload mode provides 1.5 × In for 60 seconds and 1.85 × In for 3 seconds — useful for high-inertia loads or severe-duty applications. Ground fault protection is built into the drive. Prospective line short-circuit current withstand is 31.5 kA for 150 ms, and dielectric strength between earth and power terminals is 20 kV AC. Pollution degree 2 per EN/IEC 61800-5-1 and overvoltage category II apply. The drive meets EN/IEC 60204-11, EN/IEC 60529, EN/IEC 61800-3, EN/IEC 61800-4, and EN/IEC 61800-5-1 standards.
Control I/O and system composition
Four software-configurable analogue inputs (0-20 mA / 4-20 mA, 24 V max, 250 Ω impedance) and one analogue output (same current range) handle process signals. Six discrete inputs are standard, expandable to ten with an option. The drive system comprises two plinths, a phase-shifting transformer, medium-voltage arrestors, cooling fans, a human-machine interface, and 18 power cells. Power connection uses M10 bar-type terminals accepting 6 × 40 mm² cable per phase, entry from top or bottom. Control supply is external at 220 V AC, 3 kVA. The internal cooling fan supply is 380 V AC. Optional external supplies for both control and fan are available. Electrical isolation between power and control circuits is standard.
