Fatek FBs-20MN PLC NC Positioning Main Unit – 20 Points

Fatek – FBs-20MN PLC NC Positioning Main Unit is a compact yet powerful controller specifically engineered for advanced motion control applications. Designed to bridge the gap between standard logic controllers and dedicated numerical control systems, this unit features specialized hardware to handle high-speed pulse signals with maximum precision.

Description

In the world of industrial automation, standard PLCs are often limited by the frequency and voltage levels of their I/O points when interfacing with modern servo drives. The Fatek – FBs-20MN PLC NC Positioning Main Unit overcomes these limitations by integrating professional-grade motion control features directly into the main CPU module.

The Differential Advantage Unlike standard PLCs that use 24VDC single-ended signals (which are susceptible to noise at high speeds), the FBs-20MN is equipped with 5V differential line drivers for its high-speed inputs and outputs. This allows the controller to achieve pulse frequencies up to 920 kHz, providing the high resolution needed for precise positioning tasks. This differential signaling is the industry standard for reliable communication with high-performance servo amplifiers.

Integrated System on Chip (SoC) At the core of the FBs-20MN lies Fatek’s advanced SoC technology. By consolidating the Central Processing Unit (CPU) and the Hardware Logic Solver (HLS) into a single chip, the system eliminates the processing lag associated with software-based positioning. This ensures that complex motion profiles, such as trapezoidal velocity ramps and interpolation, are executed instantly and smoothly.

Compact and Maintainable Despite its advanced capabilities, the FBs-20MN retains the user-friendly design of the FBs series. It features 7.62mm detachable terminal blocks, allowing for rapid wiring and easy maintenance without disrupting the entire control panel. This combination of performance and practicality makes it a top choice for OEM machine builders.
