Overview

The WEG CFW320D28P3T4DB20 is a Size D, 31.0A three-phase AC drive designed for 380-480V power supply systems. This industrial-grade variable frequency drive (VFD) from WEG features integrated dynamic braking with an IGBT module, providing precise motor control and energy-efficient operation for demanding applications. Key specifications include: - Rated output current: 31.0A (HD rating) - Input voltage range: 380-480V AC, three-phase - Enclosure rating: IP20 (protection against solid objects, no liquid ingress protection) - Frame size: D (compatible with WEG CFW320 series motor starters) - Braking system: Standard dynamic braking with internal IGBT This drive is engineered for compatibility with WEG's CFW320 series, supporting motor powers up to 20HP (15kW) at 460V and 15HP (11kW) at 380V. The integrated braking IGBT eliminates the need for external braking resistors in most applications, reducing system complexity and installation costs. Typical applications include: - Conveyor systems requiring controlled acceleration/deceleration - Pump and fan speed control for energy savings - Machine tool spindle drives - Material handling equipment - General industrial automation where precise speed and torque control is required The CFW320D28P3T4DB20 features WEG's proprietary control algorithms for smooth motor operation, reduced harmonic distortion, and compliance with international standards. The IP20 enclosure makes it suitable for indoor installations where environmental protection is required against dust and accidental contact, though it is not rated for outdoor or wet environments. For integration with existing systems, the drive supports standard communication protocols including Modbus RTU, Profibus DP, and CANopen (via optional cards). The drive's compact Size D frame maintains compatibility with WEG's standard mounting configurations while providing the necessary power handling capacity for medium-duty industrial applications.
