Application Scenarios
At a bottled-water plant, a 10 HP transfer conveyor had run for more than 19 years on a 1336 PLUS II drive. During a line rebalance, the original HIM failed and the motor could no longer be jogged or speed-trimmed locally. The plant initially received a quotation for a “100 HP replacement,” which would have meant a larger enclosure, heavier cable and a new upstream breaker—far more than the application required.
A correct cross-check against the motor nameplate and the original rating label confirmed that the installed drive was the 1336F-BRF100-AE-EN-A 10 HP unit. A like-for-like replacement was fitted in the same cutout, using the original conductors, motor overload settings and panel layout. With V/Hz control selected for the centrifugal load, the conveyor returned to smooth, stepless speed control and soft-started without the mechanical snatch that had previously strained the belt fasteners. The plant’s maintenance lead noted that getting the rating right had saved “a full day of panel work and a lot of copper.”

Technical Principles and Innovative Values
Innovation Point 1 — Two control laws in one panel-matched chassis. The 1336F-BRF100-AE-EN-A lets the user select V/Hz for simple pump and fan speed control, or switch to sensorless vector control where low-speed torque and dynamic response are required—loaded conveyor starts, low-shear mixing, extruder screws. Sensorless vector avoids the cost, wiring and failure points of an encoder feedback loop.
Innovation Point 2 — Built-in PID turns the drive into a standalone process controller. A process variable can be connected directly to the drive’s analogue inputs, allowing the 1336F-BRF100-AE-EN-A to maintain pump discharge pressure or conveyor speed without a PLC in the loop. For small skids and package units, this removes a controller and shortens commissioning.
Innovation Point 3 — Process-keeping stall functions rather than trip-on-transient. Beyond the standard trips for overcurrent, overvoltage, ground fault and overtemperature, the drive provides overload stall and overvoltage stall functions that hold the process running through a transient instead of faulting on it.
Innovation Point 4 — Flying start for a coasting motor. Where a free-running load must be re-engaged after a power blip, the 1336F-BRF100-AE-EN-A can pick up a coasting motor without the high-current shock of a conventional restart—valuable on fans, pumps and conveyors.
Innovation Point 5 — SCANport modularity protects existing option-card investment. The SCANport interface accepts optional DeviceNet, ControlNet and Remote I/O adapter modules, so a plant that already holds these cards can retain them when replacing a failed drive rather than re-buying the communications layer.
Application Cases and Industry Value
Case 1 — Correct-rating conveyor replacement. As described above, a bottled-water plant avoided a costly oversized-panel rework by confirming that its failed drive was a 10 HP 1336F-BRF100-AE-EN-A, not the 100 HP unit some listings describe. A like-for-like replacement restored smooth speed control and soft starting while preserving the original cable and overload configuration.
Case 2 — Constant-pressure pumping retrofit. In a water boosting set, the was fitted to a 7.5 kW pump motor with a pressure transmitter feeding the drive’s analogue input. Running in V/Hz with the built-in PID, the set maintained constant discharge pressure across a wide demand range and soft-started on every call, removing water hammer and reducing the pump starter’s maintenance exposure. The site estimated a material reduction in throttling-valve wear and a quieter, cooler motor room.
