6KM$223F50N1A1 | GE Fuji AF-300 M$II 230VAC 3 Phase 1/2HP Enclosure Type 1

The 6KM$223F50N1A1 is a 1/2 HP variable frequency drive (VFD) from Fuji Electric, part of the AF-300 M$II series. Designed for precise motor control in industrial environments, this VFD offers robust functionality with reliable performance across a wide range of applications, particularly where flexible motor speed control and energy efficiency are critical. It operates within a 3-phase power system and is designed to manage motors in automation systems requiring variable speed adjustments for energy savings, increased equipment lifespan, and optimized operational efficiency.

Operating on an input voltage range of 200-230 VAC, the 6KM$223F50N1A1 drive is compatible with standard industrial power systems, with an input current rating of 4.7 amps and a frequency range of 50/60 Hz. These specifications ensure the drive can be easily integrated into a wide array of industrial systems, making it suitable for use in regions that operate on different electrical frequencies. The 3-phase power input allows the drive to deliver consistent and stable power to connected motors, improving motor efficiency and reducing electrical losses.

The output ratings for the 6KM$223F50N1A1 drive include an output voltage range of 200-230 VAC, with an output frequency adjustable between 0.2 Hz and 400 Hz, allowing for smooth and precise control of motor speed. The drive’s output current is rated at 3 amps continuous, with a maximum capacity of 4.5 amps for up to 1 minute during peak demand. These output characteristics provide the flexibility needed for a variety of motor applications, such as pumps, fans, conveyors, and other industrial equipment, where variable motor speed and torque control are critical for operational efficiency and equipment longevity.

This VFD is housed in a NEMA 1 enclosure, which is designed for indoor use, providing protection against dust and accidental contact. The enclosure rating ensures that the drive can be installed safely in clean, dry environments such as control rooms, enclosed machinery spaces, or within industrial cabinets. The NEMA 1 rating does not provide water or moisture protection, so the drive is not suitable for outdoor or wet conditions without additional housing. The drive uses a convection cooling method, eliminating the need for an external fan assembly, which simplifies the unit’s design and reduces maintenance requirements.

The drive features a user-friendly interface on its faceplate, including a 7-segment, 4-digit LED display for real-time monitoring of system performance. The LED display alerts users to various operational parameters and faults, allowing for easy diagnostics and maintenance through fault codes displayed on the screen. This display is accompanied by five LED indicators, which provide status information regarding panel control, program mode (including Hz, amps, and volts), and operational status. The control interface also includes six buttons for easy operation: Run, Stop, FUNC/Data, PRG/Reset, and two up/down arrow keys for navigating settings and adjusting parameters. This straightforward control layout allows operators to adjust motor speed, program settings, and reset faults with ease, ensuring efficient system management.

The 6KM$223F50N1A1 is designed for reliability and ease of installation, featuring a compact design with dimensions of 158 mm in height, 109 mm in width, and 90 mm in depth, and weighing approximately 2.9 lbs. The drive’s small size and lightweight construction make it easy to mount in various industrial control panels and enclosures, saving valuable space in crowded installations. The front cover of the drive is detachable for easy access to internal components, which further simplifies installation and maintenance processes.

This drive is designed for use in environments with elevations below 1000 meters and within a relative humidity range of 20% to 95% (non-condensing). It is not suitable for environments with corrosive gases or oil mists, as these conditions could negatively impact the longevity and performance of the unit. The drive uses a 10-amp fuse for protection, ensuring that it can handle short-term electrical surges while maintaining overall safety and stability during operation.

In summary, the 6KM$223F50N1A1 from Fuji Electric is a versatile and reliable variable frequency drive designed for indoor industrial applications. Its 1/2 HP rating, 200-230 VAC input voltage, and adjustable output frequency range of 0.2-400 Hz make it suitable for a wide range of motor control tasks. The drive’s compact size, NEMA 1 enclosure, convection cooling method, and user-friendly interface make it an excellent choice for industrial environments requiring precise motor control, energy efficiency, and long-term reliability. Whether used in pumps, fans, or conveyor systems, the 6KM$223F50N1A1 delivers consistent and efficient performance, helping to optimize operational workflows and reduce energy consumption.
