Robust 1336F-B050-AN-EN-L6 AC Drive for Demanding Industrial Applications

Technical Specifications

Main Features and Advantages

The Allen-Bradley 1336F-B050-AN-EN-L6​ delivers a robust feature set that ensures reliable motor control and operational flexibility. A key advantage is its advanced sensorless flux vector control capability, which provides superior low-speed torque performance, excellent speed regulation, and fast dynamic response compared to standard Volts-per-Hertz (V/Hz) drives. This makes it suitable for more demanding applications like mixers, extruders, and certain conveying systems that experience load changes. The drive incorporates a fully digital microprocessor-based design, allowing for precise control and a wide array of programmable features, including multiple preset speeds, adjustable acceleration/deceleration ramps (linear, S-curve), and configurable fault responses.Energy savings is a major benefit of the 1336F-B050-AN-EN-L6. Its advanced control algorithms optimize motor flux for the applied load, minimizing no-load and light-load current draw, which is particularly effective in variable torque applications like centrifugal pumps and fans. The built-in programmable automatic energy saver function further reduces energy consumption. For system integration, the drive offers extensive programmable digital and analog I/O, allowing for flexible interfacing with PLCs, sensors, and pushbuttons. The comprehensive diagnostics and fault logging are accessible via the backlit keypad, enabling quick troubleshooting and minimizing downtime. The modular design allows for the addition of optional communication cards, brake IGBTs, and other accessories, providing scalability. The robust construction and proven reliability of the Allen-Bradley 1336F-B050-AN-EN-L6​ ensure long service life and dependable operation in the demanding conditions of industrial facilities.

Application Field

The Allen-Bradley 1336F-B050-AN-EN-L6​ is a versatile drive suited for numerous applications where controlling the speed of a 5HP three-phase motor is required to improve process efficiency, product quality, or energy usage.
