650 hp at 600 V — normal vs heavy duty
The ATV6B0C63T6 is a 650 hp normal-duty drive at 600 V, delivering 511 A line current and 531 kVA apparent power. In heavy-duty service the numbers drop to 550 hp, 434 A, and 451 kVA — that's the margin for constant-torque loads like conveyors or extruders that need full torque at low speed.
STO SIL 3 and the safety circuit
Safe Torque Off rated SIL 3 per IEC 61508 means the drive removes motor torque without a main contactor — the safety function lives in the control board, not an external relay. For a commissioning engineer, that translates to fewer interposing safety relays in the panel and a faster certification walk-through on a machine guarding loop.
EMC filter and cable length — 300 m
Integrated EMC filter rated for 300 m of motor cable, Category C3 per IEC 61800-3. That covers most plant-floor runs without an external output choke — the filter handles conducted emissions up to the second environment (industrial). The 50 kA prospective short-circuit current rating at the line side means the drive coordinates with a 50 kA SCCR panel without an upstream current-limiting fuse.
Fieldbus slot architecture
Slot A accepts Profibus DP V1, PROFINET, DeviceNet, Modbus TCP/EtherNet/IP, or CANopen — the same hardware carrier, different communication module. The drive also carries a native Modbus serial port (RS-485, 2-wire, 4.8 to 38.4 kbit/s) and a dual-port Ethernet/IP + Modbus TCP interface at 10/100 Mbit/s. For a controls integrator, the slot approach means the fieldbus decision can wait until the panel build phase, not the drive order date.
Harmonics and THDI <5 %
Total harmonic current distortion below 5 % at full load, meeting IEEE 519. That's the built-in active front-end or multi-pulse rectifier doing its work — no external line reactor or active filter needed for most utility compliance checks. At partial load the THDI stays low enough to avoid nuisance transformer heating in shared-bus installations.
Cabinet mount and UL type 1/12
Cabinet-mount design with UL Type 1 (finger-safe) and Type 12 (dust-tight) ratings when integrated into an enclosure. The forced-convection cooling (2 to 4.9 kHz switching frequency, derated above 4 kHz) needs clearance above and below the heatsink — plan for 150 mm minimum free air path. The line-side screw terminals and M10 motor bus bars take up to 500 MCM cable.
The ATV6B0C63T6 is a standard catalog part in the Altivar Process ATV600 family, so spares availability is stable for the foreseeable future. Quoted to order against your BOM; lead time and volume pricing confirmed at RFQ through authorized distribution.
