Medium-voltage drive for large asynchronous motors
The Schneider Electric ATV1200A7001010 is an Altivar 1200 series AC drive rated for 585 kW motor power with 700 kVA apparent power, designed for medium-voltage asynchronous motor control in the 2970-3630 V supply range. A 48-pulse diode rectifier bridge on the input side reduces line harmonics below IEEE 519 thresholds without external filters — the integrated EMC filter handles the conducted emissions side. The drive ships in a floor-standing enclosure with separate air flows for the power cells and control section, keeping the electronics compartment cooler than the main power path.
Physical footprint and site preparation
At 2670 mm high, 3960 mm wide, and 1600 mm deep, this drive needs a dedicated equipment room with overhead clearance for the vertical +/-10 degree installation tolerance and front access for the M10 bar-type power terminals. Forced convection cooling moves 19800 m³/h of air through the enclosure — the room's HVAC must handle this exhaust volume plus the 80 dB noise level from the fans and transformer.
Overload profiles and protection coordination
Standard overload rating allows 1.2 x In for 60 seconds and 1.5 x In for 3 seconds; the high overload profile extends the 1.5 x In window to 60 seconds and allows 1.85 x In for 3 seconds — match the profile to the motor duty cycle before setting the protection parameters. Ground fault protection is built into the drive, and the prospective line short-circuit current withstand is 31.5 kA for 150 ms — coordinate upstream protection to clear within this window. Dielectric strength is 28 kV AC between earth and power terminals, with overvoltage category II per EN/IEC 61800-5-1 and pollution degree 2 — verify the installation environment meets these insulation coordination requirements.
CE marked and designed to EN/IEC 60204-11, EN/IEC 60529, EN/IEC 61800-3, EN/IEC 61800-4, and EN/IEC 61800-5-1 — the drive carries the full set of European machinery and EMC directives for industrial installations. Electrical isolation between power and control circuits is standard, with an external 220 V AC, 3 kVA supply for the control section and a separate 380 V AC supply for the cooling fans — the optional external control supply at 220 V AC/DC adds redundancy for critical processes. Altitude derating applies above 1000 m: 0.6 % current reduction per 100 m up to 2000 m — factor this into the motor full-load current when installing at elevation.
No direct pin-compatible alternative exists within the Altivar 1200 family at this power level — the 585 kW rating and 48-pulse topology are specific to this order code. Confirm the motor nameplate data and supply voltage before specifying.
