Engineering Advantages
- EtherNet/IP Native Integration – The EN communication option enables seamless integration with ControlLogix, CompactLogix, and other Logix-based PLCs via standard EtherNet/IP messaging, eliminating the need for external communication adapters.
- Internal Dynamic Braking Transistor (BR) – Built-in braking transistor supports rapid deceleration of high-inertia loads when paired with an external braking resistor, reducing stopping time and improving process cycle efficiency.
- Sensorless Vector Control – Delivers high starting torque and stable speed regulation without the cost and complexity of encoder feedback, suitable for most industrial pump, fan, and conveyor applications.
- Rockwell Ecosystem Compatibility – Fully compatible with RSLogix 5000 / Studio 5000 Add-On Instructions (AOIs), DriveExplorer, and Connected Components Workbench for rapid commissioning.
- Robust Thermal Management – Forced-air cooling with intelligent thermal modeling protects power components under sustained high-load duty cycles.
- Extensive Fault Diagnostics – Onboard fault logging and configurable fault actions reduce unplanned downtime and simplify root-cause analysis.
System Architecture & Signal Flow
The 1336F-BRF75-AA-EN operates as a standalone drive node within a Rockwell Automation control architecture:
- Network Layer: EtherNet/IP (EN adapter) connects to the plant-level Logix controller via standard Cat5e/Cat6 infrastructure. Supports explicit messaging and I/O (implicit) messaging for real-time speed/torque reference and status feedback.
- Control Layer: Internal DSP-based control board executes V/Hz or sensorless vector algorithms at high update rates. Speed reference can be sourced from network, analog input (0–10 V / 4–20 mA), or preset speeds via digital inputs.
- Power Layer: Three-phase 460 V input is rectified to DC bus, then PWM-inverted to variable-frequency AC output. The internal braking transistor connects to an external resistor to dissipate regenerative energy during deceleration.
- I/O Interface: Configurable digital inputs (start/stop, direction, fault reset, preset speeds), analog inputs/outputs, and relay outputs for run/fault status signaling to PLC or DCS.

Technical FAQ
Q: Is the 1336F-BRF75-AA-EN compatible with my existing 1336 PLUS II installation?
A: Yes. The 1336F-BRF75-AA-EN is a direct catalog replacement within the 1336 PLUS II frame size F. Verify mounting dimensions and input/output wiring terminals match your existing installation. Parameter sets from the replaced drive can be uploaded via DriveExplorer for rapid recommissioning.
Q: What is the difference between the 1336F and 1336S/1336B variants?
A: The 1336F (PLUS II) is the second-generation platform with enhanced sensorless vector control, improved EMC filtering, and broader communication option availability compared to the original 1336 (PLUS) and 1336B series. The F-frame designation also indicates the physical enclosure size class.
Q: Can this drive be used with a 380 V supply?
A: Yes. The 1336F-BRF75-AA-EN accepts 380–480 V AC three-phase input, making it compatible with standard 380 V industrial supplies common in China, Europe, and other regions.
Q: Does the internal braking transistor eliminate the need for an external braking unit?
A: The internal transistor (BR option) eliminates the need for a separate braking chopper/unit. However, an external braking resistor sized to the application’s duty cycle is still required to dissipate regenerative energy. Konmask can advise on resistor sizing upon request.
Q: What programming software is required for commissioning?
A: DriveExplorer (legacy) or Connected Components Workbench (CCW) can be used for parameter configuration via the EtherNet/IP port or a 1203-USB DPI adapter. RSLogix 5000 / Studio 5000 AOIs are available for integrated Logix control.
Q: Is a spare HIM (Human Interface Module) available?
A: Yes. Compatible HIMs (e.g., 1336-GM1, 1336-PB102) are available separately. Contact Konmask for availability and pricing.
