Rating the real load — 6780 kW motor power, 6.6 kV class
The ATV1200A81106060: This drive is rated for 6780 kW motor power with a supply voltage window of 2970-3630 V. The 30-pulse diode rectifier front end draws 850 A line current and presents 8110 kVA apparent power to the network — the harmonic profile is inherently cleaner than a 6- or 12-pulse design, which matters for utility compliance at this power level. Overload capability is defined in two duty classes: standard overload handles 1.2× rated current for 60 seconds and 1.5× for 3 seconds; high overload steps up to 1.5× for 60 seconds and 1.85× for 3 seconds. The overload profile dictates whether the drive can start a high-inertia load or ride through a momentary process spike without tripping. The prospective line short-circuit current rating is 31.5 kA for 150 ms — this sets the upstream protection coordination. The drive's own ground-fault protection is integrated, and the dielectric strength between earth and power terminals is 20 kV AC.
Physical footprint and installation constraints
The drive ships in a floor-standing enclosure measuring 3040 mm high by 8970 mm wide by 1700 mm deep. The assembly includes two plinths, a phase-shifting transformer, medium-voltage arrestors, cooling fans, a human-machine interface, and 15 power cells — this is a complete drive system, not a chassis that fits into a customer panel. Cooling is forced convection moving 90000 m3/h of air at standard efficiency. The noise level at full cooling is 80 dB — plan for hearing protection in the drive room. Operating altitude derating starts at 1000 m: 0.6 % current reduction per 100 m above that. Power connection uses M10 screw-type bars with a clamping capacity of 6 × 40 mm² per phase, entry from top or bottom. Control supply is 220 V AC, 3 kVA external, with an optional 220 V AC/DC external supply. The internal cooling fan supply is 380 V AC.
I/O complement and control interface
The drive provides 4 software-configurable analogue inputs (0-20 mA / 4-20 mA, 24 V max, 250 Ohm impedance) and 2 analogue outputs of the same type. Discrete inputs number 6 standard, expandable to 10 on an optional card. Electrical isolation between power and control circuits is maintained per the design. Standards compliance includes EN/IEC 61800-3 (EMC), EN/IEC 61800-4 (harmonics), and EN/IEC 61800-5-1 (safety), plus EN/IEC 60204-11 for the machine directive. CE marking is on the nameplate.
Sourcing and compliance documentation
As an active-production item, the ATV1200A81106060 is quoted to order against the BOM quantity through authorized distribution channels. The drive carries CE marking and conforms to EN/IEC 61800 series standards. The manufacturer provides the full compliance dossier (declaration of conformity, installation manual, and EMC guide) with the shipment. No UL listing is cited in the spec record for this variant.
