Allen-Bradley 1336F-BRF100-AE-EN-HAS2-L6 Fail-Safe AC Drive

Overview

Allen-Bradley 1336F-BRF100-AE-EN-HAS2-L6 Fail-Safe AC Drive: Fault-Tolerant Control for Critical Industrial Sites

The Allen-Bradley 1336F-BRF100-AE-EN-HAS2-L6 is a 100HP ruggedized variable frequency drive from the 1336 FORCE series, engineered for continuous, fail-safe operation in the most demanding industrial environments. Designed to meet the reliability requirements of critical process loops — including chemical dosing, compressor control, conveyor drives, and pump stations — this drive delivers stable motor control even under conditions of high electromagnetic interference, voltage fluctuation, ambient heat, mechanical vibration, and airborne contaminants such as dust and moisture.

In continuous production facilities where unplanned downtime carries severe operational and financial consequences, the 1336F-BRF100-AE-EN-HAS2-L6 provides the fault-tolerant architecture needed to maintain process integrity. Its HAS2 (Harsh Environment) rating and L6 conformal coating make it suitable for deployment in control cabinets exposed to corrosive atmospheres, condensation cycles, and high-particulate environments — conditions that would rapidly degrade standard drives.

Control Cabinet Protection Strategy

Deploying the 1336F-BRF100-AE-EN-HAS2-L6 within a well-engineered control cabinet requires a coordinated approach to power quality, signal integrity, and thermal management. In high-power motor control centers (MCCs), this drive is typically paired with an Allen-Bradley 1321-3R line reactor to suppress incoming voltage spikes and reduce harmonic distortion on the supply bus — a critical measure in facilities where multiple large drives share a common power rail. Without adequate line conditioning, voltage notching and harmonic injection can cause nuisance trips and accelerate insulation degradation across the entire drive population.

For cabinet-level surge protection, the 1336F-BRF100-AE-EN-HAS2-L6 is best supported by a dedicated surge protective device (SPD) installed at the incoming feeder, particularly in outdoor substations or facilities near high-voltage switching equipment. On the output side, a dV/dt filter or output reactor — such as the Allen-Bradley 1321-M series — protects motor windings from steep voltage rise times that are characteristic of PWM drives operating at high carrier frequencies.

In EtherNet/IP-networked control architectures, this drive communicates directly with Allen-Bradley ControlLogix or CompactLogix PLCs, enabling real-time speed reference, fault diagnostics, and process variable feedback without additional gateway hardware. When integrated with a 1756-EN2T EtherNet/IP communication module, the drive supports full parameter read/write over the network, reducing commissioning time and enabling remote fault recovery. For safety-rated interlock circuits, the drive’s digital I/O can be wired into a GuardLogix safety controller or a 440C-CR30 safety relay to enforce STO (Safe Torque Off) and SS1 (Safe Stop 1) functions in accordance with IEC 62061 and ISO 13849 requirements.

Thermal management within the control cabinet is equally critical. The 1336F-BRF100-AE-EN-HAS2-L6 generates significant heat at full load, and cabinet designers should ensure adequate airflow or forced cooling — typically via a Rittal SK series cabinet cooler or equivalent — to maintain internal ambient temperatures below the drive’s 50°C operating limit. Proper thermal zoning, with the drive positioned above heat-sensitive components such as PLCs and I/O modules, further reduces the risk of thermally induced faults.

Critical Industrial Safety Applications

The 1336F-BRF100-AE-EN-HAS2-L6 is deployed across a broad range of critical industrial sectors where motor control reliability directly impacts process safety and production continuity.

In petrochemical and refinery operations, this drive controls cooling water pumps, compressor auxiliaries, and blower systems in classified hazardous areas. Its conformal coating and harsh environment rating allow installation in control rooms adjacent to process areas where hydrocarbon vapors and corrosive gases are present. The EtherNet/IP interface enables integration with DCS platforms for centralized process monitoring and emergency shutdown coordination.

In electric power generation and transmission facilities, the drive is used for forced draft fan control, boiler feed pump auxiliaries, and cooling tower fan drives. In these applications, uninterrupted motor operation is essential to grid stability, and the drive’s built-in fault logging and diagnostic capabilities allow maintenance teams to identify developing faults before they escalate to forced outages.

In mining and mineral processing, the 1336F-BRF100-AE-EN-HAS2-L6 drives conveyor systems, slurry pumps, and ventilation fans in environments characterized by heavy dust loading, high vibration, and wide ambient temperature swings. The L6 conformal coating provides a critical barrier against conductive dust contamination that would otherwise cause insulation breakdown on unprotected drive PCBs.

In water and wastewater treatment, the drive controls high-duty-cycle pump motors in lift stations, filtration systems, and aeration basins. Its ability to maintain stable speed control under variable load conditions — including dry-run protection and process feedback via PID — makes it a preferred choice for municipal utilities requiring long-term, low-maintenance operation.

In metallurgical and steel processing facilities, the drive is applied to rolling mill auxiliaries, furnace exhaust fans, and cooling bed conveyors, where high ambient temperatures and electromagnetic interference from induction heating equipment demand robust drive hardware with proven EMI immunity.

In port and marine terminal operations, the drive powers crane hoists, ship loader conveyors, and ballast pump systems, where salt-laden air and humidity cycles create aggressive corrosion conditions that the HAS2 rating and conformal coating are specifically designed to withstand.
