Product Overview

Allen-Bradley 1336F-BRF100-AA-EN Ruggedized VFD Drive: Industrial Resilience for Harsh Environments

The Allen-Bradley 1336F-BRF100-AA-EN is a 100HP (75kW) AC variable frequency drive from Rockwell Automation’s proven 1336 PLUS II series — engineered for continuous, reliable motor speed control in the most demanding industrial environments. Whether deployed in high-temperature foundries, moisture-laden water treatment facilities, dust-heavy mining operations, or vibration-intensive heavy manufacturing lines, this drive delivers the electrical resilience and thermal stability that mission-critical infrastructure demands. Its robust power architecture, combined with EtherNet/IP network integration, makes it a cornerstone component for modern industrial control systems where downtime is not an option.

Designed to operate within a wide input voltage tolerance and equipped with advanced EMI/RFI filtering, the 1336F-BRF100-AA-EN maintains stable output even in environments with significant electromagnetic interference — a common challenge in facilities running large induction motors, arc furnaces, or high-frequency welding equipment alongside sensitive PLC and DCS networks. Its built-in dynamic braking capability and adjustable carrier frequency allow precise tuning for both standard and demanding motor loads, reducing mechanical stress and extending equipment service life.

In continuous production lines — such as those found in petrochemical processing, pulp and paper manufacturing, or steel rolling mills — the 1336F-BRF100-AA-EN integrates seamlessly with Allen-Bradley ControlLogix and CompactLogix PLC platforms via EtherNet/IP, enabling real-time parameter monitoring, remote diagnostics, and coordinated motion control without additional gateway hardware. Paired with a 1756-EN2T EtherNet/IP communication module or a 1769-L33ER CompactLogix controller, engineers can implement closed-loop speed regulation with millisecond response times, ensuring process consistency even under variable load conditions.

For facilities operating distributed control architectures, the drive’s compatibility with Rockwell Automation’s Studio 5000 Logix Designer environment simplifies commissioning and parameter management across multi-drive installations. When used alongside 1336 PLUS II series companion drives such as the 1336F-BRF050-AA-EN (50HP) or the 1336F-BRF150-AA-EN (150HP), plant engineers can standardize their spare parts inventory and maintenance procedures across a unified drive family — reducing training overhead and accelerating fault recovery.

The drive’s protective feature set is comprehensive: overcurrent protection, overvoltage and undervoltage ride-through, ground fault detection, motor overload (I²t) protection, and thermal overload monitoring are all standard. In hazardous area applications — such as Zone 2 classified areas in oil and gas upstream facilities or ATEX-adjacent installations — the 1336F-BRF100-AA-EN can be housed in appropriate IP54 or NEMA 12 rated control cabinets alongside 1492 terminal blocks, 1606-XLP industrial power supplies, and 700-series safety relays to form a fully compliant motor control center (MCC) solution.

For power quality management in facilities with sensitive instrumentation, the drive pairs effectively with line reactors and output filters from the 1321 series, suppressing harmonic distortion and protecting downstream equipment including servo drives, 22F PowerFlex 4M drives, and precision measurement instruments. In water and wastewater treatment plants, where pump cavitation and variable flow demand require smooth speed ramping, the 1336F-BRF100-AA-EN’s programmable acceleration and deceleration ramps — configurable from 0.1 to 3600 seconds — provide the process control granularity that operators require.

Mining and mineral processing operations benefit from the drive’s high starting torque capability and robust short-circuit current rating (SCCR), enabling reliable startup of conveyor belt motors, crusher drives, and slurry pump systems even under full-load conditions. When integrated with a 1734 POINT I/O system or 1756 ControlLogix I/O modules, the drive’s analog and digital I/O interface allows direct feedback from field sensors — pressure transducers, flow meters, and temperature probes — enabling fully automated process control without intermediate signal conditioning hardware.

Comprehensive Protection Solutions

The 1336F-BRF100-AA-EN is rarely deployed in isolation — it functions as the motor control backbone of a broader protection and automation architecture. In a typical heavy-industry control cabinet, it operates alongside 1606-XLP series industrial power supplies that deliver clean, regulated 24VDC to the control circuit, ensuring the drive’s logic board and HMI interface remain powered even during input voltage fluctuations. Safety-rated 440C GuardMaster safety relays provide emergency stop and safe torque-off (STO) functionality, meeting IEC 62061 and ISO 13849 safety integrity requirements for machinery protection.

For network-level redundancy, the drive’s EtherNet/IP port connects to a 1783-US8T Stratix 2000 unmanaged switch or a 1783-BMS10CGL Stratix 5700 managed switch, enabling ring topology configurations that maintain communication continuity even if a single network segment fails. Upstream, a 1756-L85E ControlLogix controller running Studio 5000 Logix Designer orchestrates the drive’s speed reference, direction commands, and fault acknowledgment — all over a single EtherNet/IP connection.

In applications requiring precise torque control — such as winding machines, extruders, or centrifuges — the 1336F-BRF100-AA-EN can be supplemented with a 1336-MOD-D2 encoder feedback module, enabling closed-loop flux vector control for enhanced low-speed torque performance. For installations where harmonic distortion is a concern, a 1321-3R series line reactor installed on the drive’s input terminals reduces THD to acceptable levels, protecting upstream transformers and other sensitive loads including 22B PowerFlex 40 drives and 1769 CompactLogix I/O modules sharing the same distribution panel.

Terminal connectivity is managed through 1492-J series feed-through terminal blocks and 1492-CABLE series pre-wired cables, reducing wiring errors during installation and simplifying future maintenance. For facilities requiring remote I/O expansion, 1734 POINT I/O modules mounted on DIN rail adjacent to the drive provide additional analog inputs for process feedback signals, completing a fully integrated, diagnostics-capable motor control solution.

Application in Critical Infrastructure

In oil and gas upstream and midstream facilities, the 1336F-BRF100-AA-EN controls injection pump motors, compressor drives, and wellhead artificial lift systems where continuous, uninterrupted operation is essential. Its wide input voltage tolerance accommodates the fluctuating power quality common at remote generator-fed sites, while its robust fault logging capability — accessible via EtherNet/IP — allows maintenance engineers to diagnose and resolve issues remotely, minimizing costly site visits.

In electric power generation and transmission substations, the drive manages cooling fan motors, transformer oil pump drives, and auxiliary service motors. Its EMI filtering and shielded cable compatibility ensure that drive-generated harmonics do not interfere with protection relay systems or SCADA communication networks operating in the same facility.

Mining operations — from underground coal extraction to open-pit copper mining — rely on the 1336F-BRF100-AA-EN for conveyor belt speed control, ventilation fan regulation, and dewatering pump management. The drive’s high starting torque and programmable current limiting protect mechanical drivetrain components from shock loads during startup, extending the service life of gearboxes, couplings, and motor bearings in abrasive, dust-laden environments.

Water and wastewater treatment plants deploy this drive on primary and secondary clarifier drives, aeration blower motors, and sludge pump systems. Its smooth speed ramping eliminates water hammer in pipeline systems, reducing pipe stress and valve wear. In municipal water supply networks, where pump scheduling is coordinated with SCADA systems, the drive’s EtherNet/IP integration enables seamless participation in demand-response and energy optimization programs.

Metallurgical and steel processing facilities use the 1336F-BRF100-AA-EN on rolling mill auxiliary drives, fume extraction fan motors, and cooling water pump systems. The drive’s thermal overload protection and automatic restart capability ensure that brief process interruptions — such as those caused by upstream equipment faults — do not result in extended production shutdowns, supporting the continuous throughput demands of high-volume steel production.
