The Allen-Bradley 1336-C003-E0D is a versatile AC Adjustable Frequency Drive from the legacy Bulletin 1336 series. Engineered by Rockwell Automation, this drive is designed to provide precise speed and torque control for three-phase induction motors. The “Constant Torque” designation makes it an ideal solution for industrial applications where the load remains consistent regardless of speed, such as conveyors, positive displacement pumps, and packaging machinery. Its robust design is tailored for high-demand industrial environments requiring reliable motor management.

Product Datasheet Essentials

This drive features a sophisticated power module and logic board that work in tandem to provide adjustable acceleration/deceleration times and multiple preset speeds. The “E0D” suffix typically refers to specific factory-installed options or revision levels concerning the human interface module (HIM) or communication adapters. It includes comprehensive protection features such as instantaneous overcurrent trip, ground fault protection, and over-temperature sensing to safeguard both the drive and the connected motor.

Application Fields

The Bulletin 1336 series is widely utilized across various manufacturing and processing sectors:

• Material Handling: Driving conveyor belts and sorting systems.
• Food and Beverage: Controlling mixers, agitators, and bottling lines.
• General Manufacturing: Powering small-scale machine tools and assembly systems.
• HVAC Systems: Operating industrial fans and constant-pressure pumps.

 

Product Usage Instructions

1. Mounting: Install the drive vertically on a flat, non-flammable surface. Ensure adequate clearance (at least 4-6 inches) around the unit for proper airflow and cooling.
2. Wiring: Connect the 3-phase input power to terminals L1, L2, and L3. Connect the motor leads to U, V, and W. Ensure all grounding connections are made to the chassis to minimize EMI.
3. Programming: Use the Human Interface Module (HIM) or a serial communication link to enter motor nameplate data, including Volts, Amps, and Hertz, into the drive’s parameter set.
4. Initial Start-up: Perform a “bump test” to verify correct motor rotation. If rotation is reversed, swap any two of the three motor output leads (with power disconnected).

 

Common Questions & Answers (Q&A)

Q: Can this drive be used for Variable Torque (VT) applications like fans? A: Yes, while optimized for Constant Torque, the 1336-C003-E0D can easily handle variable torque loads. However, the sizing should always be based on the motor’s full-load amps.

Q: What should I do if I see a “Fault” light on the display? A: Consult the fault code displayed on the HIM. Common codes include F04 (Under Voltage) or F07 (Overcurrent). Check your input power stability and the mechanical load on the motor.

Q: Is this drive still in active production? A: The Bulletin 1336 is considered a legacy series. While new units are rare, they are widely available as high-quality refurbished or surplus units, and modern PowerFlex series drives are often used as migration paths.
