Rating breakdown: normal vs heavy duty
The ATV6A0C50T6: The normal duty curve (550 hp, 464 A) suits constant-torque or variable-torque loads with moderate overloads. The heavy duty curve (450 hp, 383 A) provides higher overload capacity – typically for conveyors, crushers, or extruders. The 8 kVA gap between the two duty points (482 vs 398 kVA) reflects the headroom the drive reserves for transient overloads. Select based on the motor's peak torque demand, not just the nameplate horsepower.
Safety and EMC integration
STO (Safe Torque Off) rated SIL 3 per IEC 61508 / IEC 13849-1 is standard – no separate safety module required for removal of torque. The integrated EMC filter covers 300 m of motor cable to Category C3, which is sufficient for most industrial environments; for longer runs or Category C2 installations an external filter is needed. Pollution degree 2, vibration and shock per IEC 60068-2-6/11 ms, altitude up to 2000 m with derating above 1000 m. Standards compliance includes IEC 61800-3, UL 61800-5-1 (Type 1/12 enclosure), and IEC 61000-3-12 (THDI <48% at full load).
Cabinet mounting notes
Cabinet mount only – no standalone enclosure rating. The kit composition includes the control unit, mechanical mounting kits, power connection set of fuses, and a 200 kW power module with front cover. Line side termination uses M10 x 2 bars; control wiring is via removable screw terminals (0.5–1.5 mm² / AWG 20–16). Forced convection cooling means clear airflow around the heatsink – maintain the manufacturer's minimum clearance. Slot A accepts one communication option card; Slot B is available for I/O or relay extensions. Prospective line Isc is 50 kA – coordinate upstream fuses or breakers accordingly.
Sourcing posture
The ATV6A0C50T6 is an active, current-production part (lifecycle stage: current). No obsolescence horizon announced. This is a large-drive SKU (550 hp class), typically quoted to order rather than held available via RFQ confirmation at distribution. Lead time depends on factory load and configuration – submit an RFQ for a firm delivery commitment. For BOM planning, treat it as a standard lead-time item with no risk of last-time buy.
