The Eaton Cutler-Hammer DG1-347D6FB-C21C is a robust variable frequency drive (VFD) engineered for effective motor control in industrial settings. With a power rating of 5 horsepower, this drive is adept at handling input voltages between 380 and 500 V using a three-phase configuration. Designed for versatility, it operates efficiently across 50 and 60 Hz power supplies. Its notable high overload capacity allows for a sustained rating of 7.6 A, ensuring reliable performance under demanding conditions and enabling an output power of 3 kW.

This unit is built to endure in environments requiring an enclosure protection rating of IP21, corresponding to NEMA Type 1. This level of protection provides a basic safeguard against physical contaminants while keeping the drive operational. It can output frequencies that range up to 400 Hz, allowing diverse applications. The frequency accuracy is specified at a digital resolution of 0.01 Hz and ±1% for analog signals, ensuring precise control.

Connectivity is facilitated through onboard communication interfaces, including EtherNet/IP, Modbus TCP, RS-485 Modbus RTU, and BACnet MS/TP, allowing for easy integration into varied control networks. The DG1-347D6FB-C21C supports multiple motor control modes such as frequency, speed, open-loop torque, and speed modes, making it adaptable to various motor types including induction and permanent magnet motors (both IPM and SPM).

Furthermore, the VFD’s overload capacity of 110% for one minute or 150% for two seconds within a 20-second interval provides added reliability for transient loads. The built-in protective features such as a brake chopper, DC choke, and an internal EMC filter enhance its operational integrity while mitigating electrical noise. Overall, the DG1-347D6FB-C21C represents a solid choice for industrial applications requiring effective motor control features and reliable performance.
