- Dynamic Braking Transistor (BRF): Built-in braking chopper enables rapid deceleration without external braking unit for most applications
- Sensorless Vector Control: Delivers improved low-speed torque performance without encoder feedback, reducing system complexity
- 150% Overload Capacity: Handles transient load spikes common in pump and fan applications without nuisance tripping
- Wide Input Voltage Tolerance: 380–480 V ±10% accommodates global power grid variations
- Rockwell Ecosystem Compatibility: Fully compatible with DriveExplorer, DriveExecutive, and RSLogix 5000 parameter management tools
System Architecture & Signal Flow
The 1336S-BRF30-AA-EN operates on a standard AC-DC-AC conversion architecture:
- Rectifier Stage: Three-phase AC input is rectified to a DC bus via a full-wave diode bridge
- DC Bus & Filtering: Capacitor bank smooths DC bus voltage; the BRF braking transistor connects an external resistor for regenerative energy dissipation
- IGBT Inverter Stage: PWM-controlled IGBT modules synthesize variable-frequency, variable-voltage AC output to the motor
- Control Board: DSP-based control executes V/Hz or sensorless vector algorithms; EtherNet/IP adapter provides real-time I/O and parameter access over standard Ethernet infrastructure
- I/O Interface: Analog inputs (0–10 V, 4–20 mA), digital inputs/outputs, and relay outputs for external control integration

Technical FAQ
Q: Is the 1336S-BRF30-AA-EN compatible with ControlLogix via EtherNet/IP?
A: Yes. The EN suffix denotes an embedded EtherNet/IP adapter. The drive appears as a standard EtherNet/IP device in Studio 5000 and can be configured using the 1336 PLUS EDS file available from Rockwell Automation’s product compatibility download center.
Q: Does this drive require an external braking resistor?
A: The BRF suffix confirms a built-in dynamic braking transistor. An external braking resistor (sized to application duty cycle) must be connected to the BR+ / BR- terminals. Konmask can advise on resistor sizing upon request.
Q: Can this unit replace a 1336 PLUS II or 1336 IMPACT drive?
A: Mechanical and electrical footprints differ between 1336 sub-families. Cross-reference the original catalog number and frame size before substitution. Our engineering team can assist with compatibility assessment.
Q: What is the warranty on surplus units?
A: Konmask provides a 90-day functional warranty on verified surplus units. Extended warranty options are available — contact us for details.
Q: Is export documentation available for international shipments?
A: Yes. We provide commercial invoice, packing list, certificate of origin, and HS code documentation (HS: 8504.40) for all international orders.
