Overview

The Danfoss VLT® AutomationDrive EZ FC 321 (SKU: 132L4591) is a high-performance AC drive designed for precision motor control in industrial automation. Rated at 45 kW (60 HP) with a continuous current of 80 A, this drive operates on a 525-600 V supply, making it ideal for pumps, fans, conveyors, and high-inertia loads like centrifuges and hoists. The integrated brake chopper (IGBT-based) enables fast deceleration by dissipating regenerative energy to an external brake resistor, preventing DC-link overvoltage trips during dynamic braking. Smart Start wizards simplify commissioning for common applications, reducing setup time by up to 50% compared to manual configuration. The graphical local control panel (LCP) provides plain-language readouts and allows parameter cloning between drives, streamlining machine builds or replacements. Fieldbus options include PROFIBUS DP, DeviceNet, PROFINET, Ethernet/IP, and Modbus TCP (with Modbus RTU standard), ensuring compatibility with most industrial networks. Compact and energy-efficient, the FC 321 features integrated DC link chokes and EMC filters to minimize grid pollution and reduce external component costs. The drive supports motor cable lengths up to 1,000 ft (unscreened) or 500 ft (screened), and offers 6 programmable digital inputs, 2 digital outputs, 1 analog output (0/4-20 mA), and 2 relay outputs (Form C, 240VAC/2A). Safety features include Safe Torque Off (STO) per EN 61800-5-2. With a minimum 10-year component lifetime and intelligent heat management, the FC 321 reduces maintenance costs while delivering reliable performance in demanding environments. Its flux vector control ensures stable operation across variable loads, and the drive’s compact D-frame size saves up to 68% space compared to equivalent models.

The FENA 21 DualPort module supports Three protocols Modbus-TCP, EtherNet/IP, and the PROFInet IO RT network. The Modbus-TCP protocol is simply the Modbus protocol used on top of Ethernet-TCP/IP. Modbus-TCP is an open Industrial Ethernet network which has been specified by the Modbus-IDA User Organization. EtherNet/IP is based on the Common Industrial Protocol (CIP), which is also the framework for both the ControlNet and DeviceNet network protocols. PROFInet IO RT is an open network based on the PI Organization standard.
