Product Overview

The Allen-Bradley 1336F-BRF100-AE-EN​ is a microprocessor-based adjustable frequency AC drive from the Bulletin 1336 PLUS II family, built to control the speed and, when required, the torque of three-phase induction motors. Reading the catalog number: 1336F identifies the 1336 PLUS II series, BR sets the input voltage at 380 to 480 V AC three-phase (or 513 to 620 V DC on the DC-fed variant), F100 is the nominal rating of 7.5 kW (10 HP), AE specifies an IP20 / NEMA Type 1 enclosure with EMC provisions, and EN selects the English language group. Note that this is a 10 HP drive despite the “100” in the code; some reseller listings misread it as 100 HP, and the difference matters when an existing panel is being matched.The Allen-Bradley 1336F-BRF100-AE-EN​ supports two selectable control modes: volts-per-hertz for straightforward speed control on pumps and fans, and Sensorless Vector Control where low-speed torque and dynamic response are needed without an encoder. Parameters are organised in a group and element structure and are set from the Human Interface Module or over the serial port using DriveTools software. Because the drive shares its control interface and communication options with the 1336 IMPACT and 1336 FORCE field-oriented drives, the SMC and SMP power products and the 1305 drive, the Allen-Bradley 1336F-BRF100-AE-EN​ integrates into Allen-Bradley PLC, SLC and ControlLogix architectures with the same option modules already stocked on site.The product line has been discontinued by Rockwell Automation, so the Allen-Bradley 1336F-BRF100-AE-EN​ is normally sourced as new surplus or tested stock for maintenance, retrofit and panel-matched replacement.

Technical Specifications

Main Features and Advantages

Two control modes for two kinds of load: The Allen-Bradley 1336F-BRF100-AE-EN​ can be run in V/Hz mode where the requirement is simple speed control of a centrifugal pump or fan, and switched to Sensorless Vector Control where the load needs torque at low speed — a loaded conveyor start, a mixer at low shear, an extruder screw. Sensorless vector delivers that torque without an encoder feedback device, which keeps the cost and cabling of a feedback loop out of the installation.Protection that is tuned to the machine: Beyond the standard trips for overcurrent, overvoltage, ground fault and overtemperature, the drive provides overload stall and overvoltage stall functions that hold the process running through a transient rather than tripping on it, plus a speed-sensitive electronic motor overload, flying start for a coasting motor, auto restart after a power loss, and a memory of the last four faults with plain-language diagnostics on the Human Interface Module. The Allen-Bradley 1336F-BRF100-AE-EN​ also supports DC injection braking, dynamic braking with an external resistor, slip compensation, S-curve acceleration and seven preset speeds.Process control built in: An integral process PI controller allows pressure, flow or temperature to be closed around the drive without an external loop in the PLC, and the auto-economiser function reduces motor flux at light load for additional energy saving on fan and pump duty. Three skip frequencies let mechanical resonance points be avoided, and dual accel/decel profiles cover applications with different loaded and unloaded ramps.Integration and serviceability: The SCANport interface accepts the same communication adapters used across the Allen-Bradley drive family, so a DeviceNet or ControlNet node can be added without changing the drive. The removable Human Interface Module allows the same keypad to be used for programming several drives in a lineup, and the laminated bus design and planar construction reduce internal cabling, which is where reliability is won in a panel that has been running for fifteen years.

Application Field

Fan, pump and compressor duty: The Allen-Bradley 1336F-BRF100-AE-EN​ is most frequently found on variable-torque loads where the energy case for a drive is straightforward — supply and return fans, cooling tower fans, process pumps, blowers and small compressors. Running in V/Hz with the auto-economiser active, the drive takes a motor that previously ran across the line against a throttling valve or damper and matches its speed to the actual demand.Conveyors and material handling: On belt conveyors, sortation lines and transfer cars, the drive handles controlled acceleration and deceleration, prevents product spillage on start, and provides the low-speed torque needed to break a loaded belt loose. Sensorless vector mode is normally selected here rather than V/Hz.Mixers, extruders and machine tools: Constant-torque applications such as mixers, agitators, extruder screws and small machine tool spindles use the Allen-Bradley 1336F-BRF100-AE-EN​ for speed regulation under varying load, with skip frequencies used to avoid a resonant speed band on the mechanical train.Retrofit and panel-matched replacement: The largest current demand is replacement. Panels built around the 1336 PLUS II are still in service across water treatment, cement, metals, food and beverage and general manufacturing, and when a drive fails the preference is usually a like-for-like unit that drops into the same cut-out, uses the same option modules and reads the same parameters, rather than a migration to a PowerFlex platform that requires re-engineering. The Allen-Bradley 1336F-BRF100-AE-EN​ serves that need, and its discontinued status is precisely why availability and condition of stock matter more than price on this part number.
