Application Scenarios
In a packaging machinery workshop, production engineers struggled with inconsistent conveyor speeds that caused product misalignment and jams during high-speed operation. The existing motor control method—a simple across-the-line starter—offered no speed regulation, forcing operators to accept whatever fixed speed the motor produced. When the maintenance team installed an 1336F-BRF20-AA-EN-HCS2 drive on the conveyor motor, they gained precise speed adjustment through the built-in HCS2 digital potentiometer. Operators could now fine-tune conveyor speed to match upstream and downstream equipment, eliminating jams and improving throughput by approximately 12%. The 1336F-BRF20-AA-EN-HCS2‘s NEMA 1 enclosure allowed direct panel mounting inside the existing control cabinet without additional protective housing.

Technical Principles and Innovative Values
The 1336F-BRF20-AA-EN-HCS2 employs microprocessor-based pulse width modulation (PWM) technology to convert fixed-frequency AC input power into adjustable-frequency, adjustable-voltage output for precise motor control. The drive supports both Volts/Hertz control for standard applications and sensorless vector control for enhanced torque performance at low speeds.
- Innovation Point 1 – Integrated HCS2 Human Interface Module: The 1336F-BRF20-AA-EN- includes the HCS2 programmer/controller HIM with digital potentiometer and upload/download capability as standard equipment. This interface enables technicians to configure parameters, monitor drive status, and transfer configuration files between drives without external programming tools, significantly reducing commissioning and maintenance time.
- Innovation Point 2 – Dual Control Mode Flexibility: The drive supports both standard Volts/Hertz control and advanced sensorless vector control, selectable via parameter configuration. This dual-mode capability allows the 1336F-BRF20-AA-EN- to handle simple fan and pump applications with V/Hz mode while delivering precise torque control for demanding loads requiring vector performance.
- Innovation Point 3 – DC Bus Compatibility for Common DC Systems: Beyond AC input capability, the 13 accepts 513–620V DC input, enabling integration into common DC bus configurations where multiple drives share a single rectifier front-end. This architecture reduces harmonic distortion and enables regenerative energy sharing between drives.
