Industrial Control and Drive Characteristics

The ATV630D45N4 uses Ethernet and 2-wire RS485 interfaces for control-system communication. Modbus TCP operates over Ethernet, while the serial interface supports RTU framing with configurable parity and addresses from 1 to 247. The communication interface supports 10/100 Mbit/s Ethernet and serial rates from 4800 bps to 38.4 Kbps.

The drive provides configurable analog and digital signal interfaces. AI1, AI2 and AI3 accept voltage or current signals, while AQ1 and AQ2 provide voltage or current outputs. DI7 and DI8 can operate as pulse inputs up to 30 kHz. Sampling durations are specified as 2 ms for DI1 to DI4, 5 ms for DI5 and DI6, 5 ms for analog inputs and 10 ms for AO1.

Motor control profiles include constant torque, optimized torque and variable torque for asynchronous motors, plus permanent magnet and synchronous reluctance motor profiles. Acceleration and deceleration ramps are independently adjustable from 0.01 to 9999 s. The unit uses DC injection for braking to standstill and does not include an integrated brake chopper.

Optional communication hardware includes PROFIBUS DP V1, PROFINET, DeviceNet, Modbus TCP/EtherNet/IP, CANopen, Ethernet/IP Modbus TCP/MD-Link, BACnet MS/TP and Ethernet Powerlink modules.

Field Installation Guidelines

Mount the drive vertically on a wall within the specified +/- 10 degree operating position. Maintain the required installation clearances specified by the applicable ATV630 installation documentation and ensure that forced-convection airflow is not obstructed.

Route incoming power, motor conductors and low-level control or communication wiring separately where practical to limit conducted and radiated interference. Use the specified control, line-side and motor terminal conductor ranges for the corresponding connections.

Connect protective earth and cable shields according to the installation requirements for the drive and the connected motor system. Keep communication wiring away from high-current motor conductors and avoid unnecessary parallel runs.

For ambient temperatures from 50 to 60 deg C, apply the specified current derating. Above 1000 m altitude, apply the stated current derating of 1% per 100 m.
