System Architecture & Signal Flow
The ATV630D37N4 accepts 3-phase 380–480 V AC supply through an integrated Class C2 EMC filter and rectifier stage, producing a regulated DC bus. The IGBT inverter stage synthesizes variable-frequency, variable-voltage output (0.1–500 Hz) to the motor terminals. Control logic is executed on a dual-processor architecture: one core handles real-time PWM and motor flux vector algorithms; the second manages process PID, communication stacks, and HMI. I/O expansion modules (VW3A3201–VW3A3204) can be added to the option slot for additional analog/digital channels. The integrated braking transistor connects to an external braking resistor (customer-supplied) for applications requiring rapid deceleration.
Typical Wiring Topology: PLC (Modbus TCP/IP) → ATV630D37N4 Ethernet port → Drive internal PID → Motor output → Process sensor (4–20 mA) → AI1 feedback input → closed-loop regulation.

Technical FAQ
Q: Is the ATV630D37N4 compatible with Modicon M580 PLC via EtherNet/IP?
A: Yes, with the optional VW3A3720 EtherNet/IP communication card installed. Native Modbus TCP/IP is available on the standard RJ45 Ethernet port without any additional card.
Q: Can this drive operate a permanent magnet synchronous motor (PMSM)?
A: Yes. The ATV630 supports PMSM control via the Flux Vector Control (FVC) mode with encoder feedback, or sensorless PMSM mode for applications where encoder installation is impractical.
Q: What is the derating factor above 1000 m altitude?
A: Current derating of approximately 1% per 100 m above 1000 m is required. At 2000 m, apply a 10% current derating. Consult Schneider Electric application note AN-ATV630-ALT for full derating curves.
Q: Does the drive include a line reactor or du/dt filter?
A: The integrated EMC filter provides conducted emission suppression. For long motor cable runs (>50 m) or sensitive motor insulation, an external du/dt filter (VW3A5304–VW3A5308) is recommended.
Q: What is the standard warranty and return policy?
A: Konmask.com provides a 12-month quality guarantee. DOA units are replaced within 7 business days. Contact support@konmask.com with serial number and fault description to initiate a claim.
