Allen-Bradley 2093-PRS1 Placeholder Module

Product Dimensions：

The Allen-Bradley 2093-PRS1 is a specialized Kinetix 2000 Passive Shunt Module. It is designed to work within the Kinetix 2000 multi-axis servo drive system to dissipate excess regenerative energy that occurs during motor deceleration.

1. Product Detailed Description

The 2093-PRS1 is a rail-mounted component that integrates seamlessly into the Kinetix 2000 drive line. In high-performance motion control, when a motor slows down quickly, it acts as a generator. If this energy isn’t managed, it can cause an overvoltage fault in the drive. The 2093-PRS1 monitors the DC bus voltage and redirects that excess energy into internal resistors to be dissipated as heat.

3. Product Advantages

• Space-Saving Design: The “bullet-train” slim profile allows it to fit onto the power rail without requiring significant extra cabinet space.

• Seamless Integration: It connects directly to the Kinetix 2000 power rail, eliminating the need for complex external wiring between the drive and the shunt.

• System Protection: Effectively prevents “DC Bus Overvoltage” faults, ensuring the longevity of the drive electronics and continuous machine operation.

• Passive Operation: Requires no external control logic; it activates automatically based on the DC bus voltage levels.

4. Safety & Precautions

• Heat Dissipation: The module generates significant heat during operation. Ensure there is adequate ventilation and clearance (usually 50mm or more) above and below the module.

• High Voltage: The DC bus terminals carry lethal voltages. Always wait for the bus capacitors to discharge (check the “Bus Charged” LED) before performing maintenance.

• Power Limits: Do not exceed the continuous power rating (15W). If your application requires more braking energy, you may need an active shunt or a larger external resistor.

• Correct Placement: Ensure the module is securely seated on the rail to maintain a solid electrical connection.

5. Typical Applications

The 2093-PRS1 is ideal for applications involving high inertia loads or rapid start-stop cycles, such as:

• Packaging Machinery: Rapidly moving conveyors and pick-and-place arms.

• Material Handling: Vertical lifts or automated storage and retrieval systems (ASRS) where gravity adds energy during descent.

• Textile Machines: High-speed spindles that require quick stopping.

• Printing Presses: Precise tension control requiring frequent motor braking.
