PLC Network and Drive Interface

The ATV930D45N4 provides Ethernet communication through two RJ45 interfaces. EtherNet/IP and Modbus TCP operate at 10/100 Mbit/s with half-duplex, full-duplex, and autonegotiation modes. Modbus serial communication uses a 2-wire RS 485 physical interface with RTU framing and configurable 8-bit data with odd, even, or no parity.

The drive also supports optional communication modules for PROFINET, PROFIBUS DP V1, DeviceNet, EtherCAT, CANopen, and Ethernet Powerlink. Optional digital and analog I/O expansion modules and encoder interface modules can extend the control interface.

The drive control section provides three analog inputs, two analog outputs, programmable digital inputs, pulse inputs, relay outputs, and Safe Torque Off inputs. Analog inputs accept voltage or current signals, while the analog outputs can provide voltage or current references.

Frequently Asked Questions

Q: What motor power ratings are specified for the ATV930D45N4?

A: The drive is rated for 45 kW under normal-duty operation and 37 kW under heavy-duty operation.

Q: Does the ATV930D45N4 include a braking chopper?

A: Yes. The specified variant includes an integrated braking chopper.

Q: What are the specified operating temperature limits?

A: Operation is specified from -15 to 50 deg C without derating and from 50 to 60 deg C with a derating factor.

Field Installation Guidelines

Mount the drive vertically within the specified +/- 10 degree installation position. Provide the required clearance and airflow around the enclosure so that the cooling system can maintain the specified thermal conditions.

Separate power wiring from low-level control and communication wiring. Route Ethernet and RS 485 cables away from motor and mains conductors where practical. Use appropriate shield termination and grounding practices for the selected communication and EMC installation method.

Connect line, motor, DC bus, control, and protective-earth conductors to the designated terminals. Verify conductor cross-sections against the installation documentation before energization. The specified terminals accept 35-50 mm2 line conductors, 50 mm2 motor conductors, and 35-50 mm2 DC bus conductors.

Before commissioning, verify supply voltage, motor connections, protective earth continuity, STO wiring, communication addressing, and configured motor parameters. Do not apply control signals until the power wiring and safety circuit have been checked.
