PLC Network and Drive Control Characteristics

The ATV930D15N4 provides Ethernet communication through Modbus TCP and EtherNet/IP, with 10/100 Mbit/s transmission and configurable half-duplex or full-duplex operation. The RS 485 interface supports Modbus RTU with 8-bit data and configurable odd, even, or no parity.

The drive accepts programmable 24 VDC discrete signals through DI1 to DI8. DI7 and DI8 can operate as pulse inputs up to 30 kHz. Three analog inputs support either voltage or current operation, including 0 to 10 VDC and 4 to 20 mA signals. The analog inputs use 12-bit conversion.

Motor control profiles include variable torque, optimized torque, and constant torque operation for asynchronous motors. Permanent magnet and synchronous reluctance motor profiles are also supported. Acceleration and deceleration ramps are independently adjustable from 0.01 to 9999 s.

The integrated braking chopper provides a direct DC bus interface for braking circuitry. The drive also supports DC injection braking and four-quadrant operation.

Frequently Asked Questions

Q: What input voltage range is specified for the ATV930D15N4?

A: The rated three-phase supply range is 380 to 480 VAC, with a stated relative symmetric mains voltage tolerance of 10 %.

Q: What communication interfaces are integrated into the drive?

A: The drive provides Ethernet with Modbus TCP and EtherNet/IP, plus a two-wire RS 485 interface for Modbus serial communication.

Q: Does the ATV930D15N4 provide Safe Torque Off?

A: Yes. STO is implemented through the STOA and STOB inputs. The drive also supports SS1, SLS, and SBC/SBT safety functions.

Field Installation Guidelines

Mount the drive vertically with the specified operating position of plus or minus 10 degrees. Maintain sufficient clearance around the enclosure for the specified forced-convection airflow and heat dissipation.

Connect line-side, motor, and DC bus conductors to their designated screw terminals. The specified conductor ranges are 10 to 16 mm2 for line, motor, and DC bus connections, and 0.5 to 1.5 mm2 for control terminals.

Route motor power conductors separately from low-level analog and communication wiring. Use appropriate shield termination and grounding practices for analog signals, RS 485, and Ethernet cabling. Keep shielded signal paths separated from high-current switching conductors to reduce conducted and radiated interference.

Verify the protective earth connection before energization. Confirm supply voltage, motor wiring, control input polarity, STO wiring, and communication addressing before commissioning.

For installation above 1000 m altitude or operation above 50 deg C, apply the specified output-current derating. Do not obstruct the cooling airflow path.
