4857 kW motor power — what it means for the installation
The ATV1200A58105555 is rated for 4857 kW on the motor shaft, with an apparent power of 5810 kVA at the input. That puts it squarely in the medium-voltage drive class — this isn't a 480 V unit you hang on a wall. It's a floor-standing cabinet, 3040 mm tall, 7770 mm wide, 1800 mm deep, with separate air flows for the power cells and the phase-shifting transformer. The 30-pulse diode rectifier bridge on the input side means harmonic distortion is inherently low — no active front end needed for IEEE 519 compliance on most grids. That saves a chunk of engineering review time during commissioning.
Overload capability and supply interface
Overload profiles are specified for both standard and high overload: 1.2× In for 60 s standard, 1.5× In for 3 s standard, and 1.5× In for 60 s or 1.85× In for 3 s on the high overload setting. That covers heavy starting duty on synchronous or asynchronous motors without oversizing the drive. Supply voltage limits are 2970…3630 V — a 3.3 kV class medium-voltage bus. The line current is 720 A at full load. The prospective short-circuit current rating is 31.5 kA for 150 ms, so upstream protection coordination needs to clear within that window to keep the drive alive. Electrical connection uses M10 bar-type terminals, clamping 6 × 40 mm² per phase, entry from bottom or top. That's a big cable — plan the gland plate and bending radius early.
Built-in diagnostics and control wiring
The drive ships with 4 software-configurable analogue inputs (0…20 mA / 4…20 mA, 24 V max, 250 Ω impedance) and 2 analogue outputs of the same type. Discrete inputs are 6 standard, expandable to 10 with an option. That's enough I/O for basic speed reference, feedback, and run/stop without a separate PLC for the drive itself. Control power comes from an external 220 V AC supply at 3 kVA — the cooling fan runs off 380 V AC. That means the control electronics stay alive even if the main power is off, which is handy for diagnostics before a start. The integrated EMC filter and electrical isolation between power and control save external filtering hardware. The product composition includes the phase-shifting transformer, medium-voltage arrestors, 15 power cells, cooling fans, and a human-machine interface. That's a complete medium-voltage drive package — not a chassis you build around.
Compliance and environmental limits
CE marked and compliant with EN/IEC 60204-11, EN/IEC 60529, EN/IEC 61800-3 (EMC), EN/IEC 61800-4, and EN/IEC 61800-5-1 (safety). That covers the machinery directive, EMC for industrial environments, and functional safety for the drive system. Pollution degree 2, overvoltage category II per the same standard. Operating altitude is 1000…2000 m with a 0.6 % current derating per 100 m above 1000 m. Relative humidity 0…90 %, with an optional 0…95 % rating. Operating position vertical ±10°. Noise level is 80 dB — hearing protection zone signage needed near the cabinet.
