Product details

The ATH630U30N4Z is a standard version Altivar HVAC ATH600 drive sized for a 3.0 kW (normal duty) or 2.2 kW (heavy duty) motor on 380-480 V three-phase supply. Normal-duty line current draws 5.371 A at 380 V, 4.6 A at 480 V; heavy-duty draws 4.2 A at 380 V, 3.6 A at 480 V. Apparent power is 3.8 kVA normal duty, 3.0 kVA heavy duty. Integrated Class C2 EMC filter covers conducted emissions for most commercial installations without an external filter. Safe torque off (STO) is rated SIL 3 per IEC 61508 and PL e per ISO 13849-1, meeting machine safety requirements for unexpected startup prevention.

Integration notes

Cabinet-mount unit, 145 mm wide, 197 mm tall, 166 mm deep. Vertical operating position only. Pollution degree 2 environment. Control circuit requires an external 24 V DC supply (19...30 V). Internal 24 V DC supply for digital inputs and STO (20.4...27 V). Internal 10.5 V DC reference for potentiometer (<10 mA). Communication via 2-wire RS-485 with Modbus RTU or BACnet MS/TP; optional communication modules for BACnet IP, PROFINET, or Ethernet IP/Modbus TCP fit the option card slot.
