Allen-Bradley 1336F-BRF100-AE-EN-A: Force Series 100 HP 480V AC Motor Drive

Technical Specifications

Main Features and Advantages

The Allen-Bradley 1336F-BRF100-AE-EN-A​ drive is distinguished by its robust performance and application flexibility. A core feature is its advanced Sensorless Vector control capability, which provides superior low-speed torque and dynamic response compared to standard V/Hz control. This allows the 1336F-BRF100-AE-EN-A​ to handle demanding applications with varying loads, such as extruders or centrifuges, without the need for a feedback encoder, simplifying installation and reducing cost. The drive incorporates a full set of programmable features, including multiple preset speeds, analog and digital I/O, and a built-in PID controller. This enables it to act as a standalone process controller, for instance, maintaining pump discharge pressure or conveyor speed based on a sensor input directly connected to the drive.Robust Protection and Seamless Integration: The 1336F-BRF100-AE-EN-A​ is built for reliable operation in harsh industrial environments. It includes comprehensive motor and drive protection features like electronic motor overload thermal protection, ground fault detection, and advanced fault diagnostics that log the last three faults with associated conditions, greatly simplifying troubleshooting. Its modular design, centered on the DPI (Drive Peripheral Interface) port, is a significant advantage. This allows for easy integration of a wide array of optional accessories, such as communication adapters for DeviceNet or ControlNet, I/O expansion cards, and dynamic braking transistors. This modularity ensures the Allen-Bradley 1336F-BRF100-AE-EN-A​ can be tailored to specific application needs and seamlessly integrated into both new and existing Rockwell Automation architecture, protecting the investment and ensuring long-term supportability. The drive’s proven reliability and extensive application knowledge base make it a trusted choice for critical, high-power motor control.

Application Field

The Allen-Bradley 1336F-BRF100-AE-EN-A​ 100 HP AC drive is engineered for demanding, high-power applications across a broad spectrum of process and discrete manufacturing industries. In the oil & gas and chemical sectors, it is extensively used for controlling large pump motors in water injection, pipeline transfer, and refinery circulation services. Here, the 1336F-BRF100-AE-EN-A​ enables precise flow control, reduces water hammer through soft starting and stopping, and generates substantial energy savings by matching pump speed to process demand rather than throttling flow with valves. Its robust construction is suited to the challenging environments of these industries.In power generation and heavy infrastructure, this drive is a workhorse for induced draft (ID) and forced draft (FD) fan control on boilers, as well as for large cooling tower fan and pump applications. The drive’s Sensorless Vector control provides the necessary torque and response for these high-inertia loads. Within mining and minerals processing, the Allen-Bradley 1336F-BRF100-AE-EN-A​ drives conveyor systems, crushers, and large slurry pumps, where its robust overload capability and protective features guard against process upsets. Similarly, in water and wastewater treatment, it controls the critical pumps for raw water intake, transfer, and aeration blowers, optimizing energy consumption—often the plant’s largest operating cost. The 1336F-BRF100-AE-EN-A​ is also found in heavy discrete manufacturing, such as metal rolling lines or large plastic extrusion machinery, where its precise speed regulation is essential for product quality. Its ability to interface with Rockwell’s control networks (via optional cards) makes it a strategic component in fully integrated plant-wide automation strategies.
