Product details

Drive ratings and duty selection

The ATV9A0C40Q4 is a modular Altivar Process ATV900 drive sized for 400 kW at 400 V normal duty and 315 kW at 400 V heavy duty, with corresponding line currents of 681 A and 545 A. The normal-duty figure governs continuous fan/pump loads; the heavy-duty figure applies to constant-torque conveyors or extruders where overload margin matters.

Safety and compliance

Safe Torque Off (STO) is integrated at SIL 3, covering both drive and motor thermal protection, phase loss, overcurrent, and DC bus overvoltage. The drive complies with IEC 61800-3, IEC 61800-5-1, IEC 61000-3-12, IEC 60721-3, IEC 61508, and IEC 13849-1. The integrated EMC filter meets category C3 for 300 m motor cable runs. CE marked.

Communication and I/O options

Two RJ45 ports for Ethernet IP/Modbus TCP on the control block, plus one RJ45 for Modbus serial. Slot A accepts Profibus DP, PROFINET, DeviceNet, EtherCAT, or CANopen modules; slot B takes encoder interfaces; slot C handles relay or I/O extension. Modbus serial runs RTU frames at 4.8 to 38.4 kbit/s, addressing 1–247 slaves.

Cabinet-mount, forced-convection cooled. Rated IP00 for integration into IP21 or IP54 enclosures. Operates at altitudes up to 4800 m with derating above 1000 m. Switching frequency adjustable 2–8 kHz; derate above 2.5 kHz. Pollution degree 2.
