Industrial Control and Drive Communication

The ATV930C22N4 exchanges control and diagnostic data through Modbus serial, Modbus TCP, and EtherNet/IP interfaces. Ethernet communication operates at 10/100 Mbit/s with half-duplex, full-duplex, and auto-negotiation modes. The serial Modbus interface uses RS-485 physical signaling with RTU framing and configurable odd, even, or no parity.

The drive provides 10 programmable discrete inputs, three analog inputs, two analog outputs, and three relay outputs. DI7 and DI8 can operate as pulse inputs up to 30 kHz. Analog inputs accept 0 to 10 VDC or 0 to 20 mA / 4 to 20 mA signals. Optional communication and I/O modules support additional network and signal interfaces.

Motor control profiles include constant torque, variable torque, and optimized torque modes for asynchronous motors, plus permanent magnet and synchronous reluctance motor control. The drive supports 4-quadrant operation, adjustable acceleration and deceleration ramps from 0.01 to 9999 s, and a maximum output frequency of 599 Hz.

Frequently Asked Questions

A: The documented safety functions include Safe Torque Off (STO), Safe Stop 1 (SS1), Safely Limited Speed (SLS), and Safe Brake Management (SBC/SBT).

Field Installation Guidelines

Mount the drive vertically within the specified +/- 10 deg position range. The enclosure is rated IP00, so installation requires an appropriate protective enclosure or cabinet providing the required environmental and personnel protection.

Route line-side power conductors, motor conductors, control wiring, and communication cables according to the installation manual. Keep low-level analog and communication wiring separated from high-current motor and input power conductors.

Connect protective earth before energizing the power circuit. Maintain the specified conductor cross-sections and terminal arrangements for line, motor, DC bus, and control connections. Shielded signal and communication cables should be terminated according to the applicable EMC installation practice.

Provide the required forced-convection cooling path. The specified cooling air volume is 860 m3/h. Verify cabinet airflow, ambient temperature, altitude, and drive derating requirements before commissioning.

For EtherNet/IP, Modbus TCP, and RS-485 connections, verify cable routing, connector seating, network addressing, and termination requirements before applying control commands. Do not route communication cables in parallel with high-current motor conductors unless the installation method provides the required EMC separation.
