Industrial Drive Control and Network Interfaces

The ATV630C31N4 provides Ethernet and 2-wire RS485 physical interfaces. Modbus TCP operates over Ethernet, while Modbus RTU is available through the serial interface with configurable transmission rates from 4800 bps to 38.4 Kbps. Ethernet supports 10 and 100 Mbit/s operation with half-duplex, full-duplex, and autonegotiation modes.

The drive accepts configurable analog voltage and current signals through three analog inputs and provides two configurable analog outputs. Digital inputs include DI7 and DI8 pulse-input capability up to 30 kHz at 24 VDC. Optional communication modules include PROFINET, EtherNet/IP, DeviceNet, Profibus DP V1, CANopen, BACnet MS/TP, and other listed interfaces.

Motor control profiles include constant torque, optimized torque, and variable torque modes for asynchronous motors, plus permanent-magnet and synchronous-reluctance motor control profiles. The switching frequency is adjustable within the specified 2 to 8 kHz range, subject to the applicable derating conditions.

Frequently Asked Questions

Q: What motor types can the ATV630C31N4 control?
A: The drive supports both asynchronous and synchronous motors, including permanent-magnet and synchronous-reluctance motor control profiles.

Q: What communication interfaces are integrated?
A: The drive has Ethernet and 2-wire RS485 interfaces. Modbus TCP is available through Ethernet, and Modbus RTU is available through the serial interface.

Q: Does the ATV630C31N4 provide a safety torque-off function?
A: Yes. Safe Torque Off (STO) is listed as an integrated safety function with SIL 3 classification.

Field Installation Guidelines

Mount the drive vertically within the specified +/- 10 deg operating position. Provide sufficient clearance for the forced-convection cooling path and maintain the specified ambient temperature limits. At temperatures above 40 deg C, apply the documented current derating.

Use the specified removable screw terminals for control wiring and the specified line-side and motor-side terminals for power connections. Keep control and communication wiring separated from high-current motor conductors where practical to reduce conducted electrical interference. Connect cable shields and protective earth according to the applicable installation standard and the drive installation documentation.

Verify supply voltage, motor connection, protective devices, STO wiring, communication addressing, and configured I/O before energization. The product data specifies isolation between power and control terminals and provides dedicated protection functions for motor phase loss, overcurrent, short circuit, DC bus overvoltage, undervoltage, overheating, and related drive conditions.
