The ATV630D45M3US: The 176 A nominal output current is the headline number for sizing the drive to the motor. For a 45 kW normal-duty induction motor on a 200-240 V line, this drive covers the full-load amp draw with headroom. The 2.5 kHz switching frequency is the default; if you need lower audible noise, expect a derating on output current. The drive includes STO (Safe Torque Off) rated SIL 3, which removes the need for an external safety contactor in many machine-safety circuits. It also carries an adjustable PID regulator, making it suitable for closed-loop process control (pressure, flow, level) without an external controller.
The ATV630D45M3US is a wall-mount drive with IP21 protection (UL Type 1), intended for indoor panel or machine mounting. It operates on a 200-240 V three-phase supply at 50-60 Hz (±5%). The drive is designed for both asynchronous and synchronous motors, covering the majority of process and utility applications (pumps, fans, compressors, conveyors). Communication is built in via Ethernet, Modbus TCP, and Modbus serial. For fieldbus integration (PROFIBUS, PROFINET, DeviceNet, CANopen, EtherNet/IP, BACnet, Powerlink), the drive accepts option cards in Slot A and Slot B. The same slots also accept digital/analog I/O extension modules and output relay modules, so you can tailor the I/O count without changing the base drive.
Compliance and environmental notes
The drive is TAA compliant via COTS, meeting U.S. federal procurement requirements. It is certified to UL 508C, IEC 61800-3 (environment 1 category C2 and environment 2 category C3), IEC 61800-5-1, IEC 61000-3-12, IEC 60721-3, IEC 61508, and IEC 13849-1. The unit ships without an internal EMC filter, so you will need an external filter if the installation requires conducted emission limits below the unfiltered level. Ambient conditions: 5-95% relative humidity without condensation.
