Product details

Motor power and duty-cycle selection

The ATH630D11N4Z: Rated 11 kW for normal duty and 7.5 kW for heavy duty at 480 V, with corresponding line currents of 16 A (normal) and 11 A (heavy) at 480 V.

Safety integration: STO and SIL 3

Safe Torque Off (STO) function is built in, certified to SIL 3 per IEC 61508 and PL e per ISO 13849-1. This removes the need for an external safety relay on the drive output when the safety circuit demands a torque-off path — the drive handles it internally, reducing panel wiring and component count.

Fieldbus and I/O flexibility

Native dual-protocol support: Modbus RTU and BACnet MS/TP over a 2-wire RS-485 physical layer. Optional communication modules add BACnet IP, PROFINET, or Ethernet IP/Modbus TCP. The integrated C2 EMC filter meets conducted emission limits for first-environment (residential) installations without an external filter.

Application-specific firmware functions

Includes fire mode, forced fire mode, run permissive, PID controller with three additional PID loops, damper control, underload detection for broken belt, scroll compressor management, skipped frequencies, catch on the fly, and cybersecure firmware update. These are pre-loaded — no option card required for the core HVAC sequences.
