Allen-Bradley 1336F-BRF100-AE-EN-HAS2-L6 AC Drive – 1336 FORCE

Allen-Bradley 1336F-BRF100-AE-EN-HAS2-L6: 100HP Flux Vector AC Drive in Industrial Control Architecture

The 1336F-BRF100-AE-EN-HAS2-L6 occupies a well-defined position in closed-loop motor control topology. As a 100 HP member of Rockwell Automation’s 1336 FORCE series, this drive implements full flux vector control — a method that decouples the magnetizing current component from the torque-producing component in real time, enabling sub-10ms torque response without a physical encoder in sensorless mode, and sub-5ms with encoder feedback engaged. In process-critical loops — compressor surge control, extruder melt pressure regulation, centrifuge deceleration ramps — this response bandwidth directly determines whether the control loop closes with stability or hunts.

The AE suffix designates a 460V AC three-phase input rating, placing this unit squarely in North American and international 480V distribution infrastructure. The EN enclosure (NEMA 1) is designed for panel-mount deployment inside MCC cabinets or control rooms where ambient contamination is managed at the enclosure level. The HAS2 designation confirms an integrated Human Interface Module (HIM) is factory-fitted, eliminating the need for a separate programming pendant during commissioning. The L6 firmware revision carries specific parameter set enhancements relevant to flux vector tuning stability and fault diagnostics depth.

Technical Parameters

Hardware Logical Analysis

The 1336 FORCE power stage is built around an IGBT inverter bridge rated for the full 100 HP output envelope. The gate drive circuitry uses isolated bootstrap supplies per phase leg, preventing common-mode ground loops from corrupting switching timing — a failure mode that manifests as asymmetric phase current waveforms and elevated motor heating in lesser designs. The DC bus capacitor bank is sized for a minimum 100ms ride-through at full load, providing immunity to brief utility voltage sags without triggering an undervoltage fault and nuisance trip.

EMC performance is addressed at the hardware level through a multi-stage approach: an integrated line reactor equivalent reduces dV/dt stress on motor insulation and attenuates harmonic current injection back into the supply bus. The control board is physically separated from the power section by a grounded metal barrier, and all analog signal traces are routed away from PWM switching nodes. This layout discipline keeps common-mode noise below the threshold that would corrupt 4–20mA process signals sharing the same cabinet.

The flux vector algorithm executes on a dedicated DSP with a 1ms current regulation loop and a 4ms velocity loop. The motor model parameters — stator resistance, rotor time constant, magnetizing inductance — are identified during an autotune sequence and stored in non-volatile memory. This means the drive can reconstruct rotor flux position from terminal voltage and current measurements alone, achieving torque accuracy within ±2% of rated without encoder hardware in sensorless mode. For applications requiring tighter speed regulation (±0.01% of base speed), the encoder feedback path through the 1336F encoder option board closes the velocity loop with hardware-level precision.

The fault log architecture stores the last 8 fault events with timestamp, output frequency, output current, and DC bus voltage at the moment of fault — four data points that are sufficient to reconstruct the electrical state of the drive at fault time and distinguish between load-side faults (overcurrent, ground fault) and supply-side events (overvoltage, phase loss).

System Integration Benefits

• Deterministic torque response: The flux vector control loop delivers torque commands within 5ms in closed-loop mode, enabling tight integration with PLC scan cycles on ControlLogix or SLC 500 platforms without introducing phase lag into the control loop.
• Backward-compatible DPI communication: The Drive Peripheral Interface port accepts all 1336-series communication adapters, allowing this unit to replace legacy 1336 PLUS or 1336 IMPACT drives in existing Remote I/O or DH+ networks without rewiring or PLC program changes.
• Programmable I/O mapping: All six digital inputs and three relay outputs are software-configurable to any of 30+ drive functions, eliminating the need for external relay logic for common interlocks such as run permissive, fault reset, and speed-at-setpoint indication.
• Integrated HIM diagnostics: The HAS2 panel provides real-time display of output frequency, output current, DC bus voltage, and fault codes without requiring a laptop or handheld programmer, reducing mean time to diagnose (MTTD) during production incidents.
• Motor thermal model: An internal electronic thermal overload model tracks motor I²t accumulation and generates a pre-fault warning before the motor protection trip, allowing the process to be ramped down in a controlled manner rather than experiencing an abrupt stop.
• Adjustable carrier frequency: The 2–10 kHz PWM carrier range allows acoustic noise optimization for occupied environments while maintaining full output current capability at lower carrier settings, avoiding the derating penalty that affects drives with fixed high-frequency carriers.
• Process PID block: An onboard PID function block accepts a 4–20mA process variable input and generates a speed reference output, enabling closed-loop pressure or flow control without consuming a PLC analog output channel or PLC program scan time.
• Fault queue with electrical context: Eight-event fault log with per-event electrical state capture (frequency, current, bus voltage) provides the data density needed for root cause analysis without external data logging hardware.

Quality Assurance & Global Logistics

Every unit of the 1336F-BRF100-AE-EN-HAS2-L6 dispatched from our Xiamen, China facility is a genuine Allen-Bradley OEM product. Authenticity verification follows a documented protocol: catalog number and serial number format are cross-referenced against Rockwell Automation’s published naming conventions; label print quality, holographic elements, and housing parting-line geometry are inspected against known-genuine reference units; and where stock condition permits, a power-on functional check confirms the drive initializes, completes its self-test sequence, and displays correct firmware revision on the HIM.

Xiamen’s position as a major southern China export hub provides direct access to international freight infrastructure. DHL Express and FedEx International Priority shipments to North America and Europe typically achieve 3–5 business day door-to-door transit. For Southeast Asia and Middle East destinations, 2–4 day express options are available. Sea freight consolidation is offered for multi-unit project orders where lead time permits. All export documentation — commercial invoice, packing list, HS code classification (8504.40 for static converters), and certificate of origin — is prepared to the standard required by major customs authorities, minimizing clearance delays.

Units are packed in anti-static polyethylene foam inserts within double-wall corrugated cartons, with corner protection rated for the drop heights specified in ISTA 2A transit testing. Each shipment includes an inspection record documenting the verification steps completed prior to dispatch. The 12-month warranty covers defects in materials and workmanship from the date of shipment; warranty claims are processed with a target response time of 48 hours from receipt of the defective unit.
