Product details

The Schneider Altivar Process ATV6A0C40Q4 is a modular variable speed drive rated for 400 kW normal duty and 315 kW heavy duty at 400 V three-phase, drawing 681 A line current in ND and 545 A in HD. The integrated EMC filter meets IEC 61800-3 category C3 with up to 300 m of motor cable, saving an external filter. Safety function STO (Safe Torque Off) is built in at SIL 3, eliminating the need for a separate safety relay for torque-off on the motor. Slot A accepts communication modules for Profibus DP V1, PROFINET, DeviceNet, Modbus TCP/EtherNet/IP, or CANopen (daisy chain RJ45, SUB-D 9, or screw terminals). Slot A and slot B also accept digital/analog I/O extension or output relay extension modules, giving flexibility for application-specific I/O without a separate remote rack.

Power and Ratings

Apparent power is 472 kVA at 400 V normal duty and 378 kVA at 400 V heavy duty. Output voltage is limited to the supply voltage (no boost), and the drive covers 50-60 Hz supply with ±5% tolerance. For installations above 1000 m altitude, derate current by 1% per 100 m up to 4800 m. Line supply harmonics: maximum THDI is <48% full load per IEC 61000-3-12, reducing the need for external line reactors in many applications. Pollution degree 2 per IEC 61800-5-1, suitable for typical control panel environments.

Communications and Control

Embedded Ethernet/Modbus TCP slave with half/full duplex and auto-negotiation at 10/100 Mbit/s. Modbus serial on 2-wire RS-485 at 4.8-38.4 kbit/s, RTU format, with configurable parity. The option slot expands to other fieldbuses as listed. Analog input accuracy: ±0.6% over 60°C temperature variation; linearity error ±0.15% of max value. Analog output accuracy ±1% over 60°C; linearity ±0.2%. Sampling times: discrete inputs 2 ms/5 ms, analog inputs 5 ms, analog output 10 ms. Relay outputs refresh within 5 ms (±0.5 ms).

Standards compliance includes IEC 61800-3 (EMC), IEC 61800-5-1 (safety), IEC 61000-3-12 (harmonics), IEC 60721-3 (environmental), IEC 61508 and IEC 13849-1 (functional safety). CE marked.

Mounting and Environmental

Cabinet mount only, forced convection cooling. Rated for operating temperature 0-50°C (no derating quoted), relative humidity 5-95% non-condensing per IEC 60068-2-3. Shock resistance 7 g for 11 ms per IEC 60068-2-27.

Frequently asked questions

What communication options does this drive support?

Embedded Modbus TCP and Modbus serial. Option slot A supports Profibus DP V1, PROFINET, DeviceNet, Modbus TCP/EtherNet/IP, CANopen (three connector variants). Slots A and B accept digital/analog I/O or relay extension modules.

What safety functions are included?

Safe Torque Off (STO) to SIL 3, integrated. Additionally, the drive provides thermal protection for motor and drive, overcurrent, short-circuit, overvoltage, undervoltage, phase loss, and overspeed protection.

What is the required external supply for digital inputs?

24 V DC (19...30 V) for the digital inputs, with a separate internal supply for the reference potentiometer (10.5 V DC ±5%, 1-10 kOhm), and internal supply for STO and digital inputs (24 V DC 21...27 V, <200 mA, with overload and short-circuit protection).
