Allen Bradley 20BD248A0ANNAND0 PowerFlex 700 AC Drive

Applications and Industrial Motor Control

The Allen Bradley 20BD248A0ANNAND0 is a PowerFlex 700 AC Drive designed for large industrial motor-control applications. This configuration operates from a 480 VAC, three-phase supply and provides 248 A continuous output current, with a 200 HP normal-duty rating and 150 HP heavy-duty rating.

The drive uses a Frame 6 architecture, IP20 / Type 1 enclosure with conformal coating, and vector control with 120V I/O. It is configured without a communication module, brake IGBT, internal brake resistor, or motor feedback. An EMC filter with common-mode choke is included for the specified second-environment installation requirements.

Typical applications include:

• Large conveyor and material-handling systems
• Industrial pumps and fluid-processing equipment
• Fans and ventilation systems
• Compressors and large rotating machinery
• Manufacturing and production lines
• Packaging and processing equipment
• Process-control machinery
• Heavy industrial motor applications
• PowerFlex 700 retrofit projects
• Industrial drive replacement and maintenance

This configuration is particularly relevant where a high-current PowerFlex 700 drive is required and the existing control architecture is based on 120V I/O.

Key Features and Industrial Advantages

248 A continuous output
The drive provides 248 A continuous output current, with 273 A available for one minute and 372 A for three seconds under the specified normal-duty conditions.

480 VAC three-phase operation
The 20BD248A0ANNAND0 is designed for 480 VAC, three-phase industrial power systems and is suitable for large motor applications within its rated operating range.

200 HP normal-duty rating
The configuration provides a 200 HP normal-duty rating and 150 HP heavy-duty rating, allowing engineers to select the appropriate duty classification according to the application.

Vector control with 120V I/O
The drive uses vector control with 120V I/O, providing a practical interface for industrial control panels and existing automation systems using this control-voltage architecture.

Frame 6 design
The Frame 6 construction accommodates the drive's high-current industrial application and is appropriate for larger motor-control installations.

EMC filtering and common-mode choke
The drive includes an EMC filter with common-mode choke, supporting electromagnetic compatibility requirements for the specified second-environment installation.

No internal braking hardware
This configuration does not include a brake IGBT or internal drive-mounted brake resistor. Applications requiring braking or regenerative-energy management need to be engineered accordingly.

No internal communication module
The base configuration does not include a communication module. Where networked control is required, the system architecture should be reviewed to determine the appropriate communication solution.

10 Technical FAQs

1. What is the output rating of the 20BD248A0ANNAND0?
The drive provides 248 A continuous output current. Its normal-duty rating is 200 HP, while the heavy-duty rating is 150 HP.

2. What is the input voltage of this PowerFlex 700 drive?
The 20BD248A0ANNAND0 is designed for a 480 VAC, three-phase input supply. The incoming plant power should be verified before installation.

3. What type of control does this model use?
This configuration uses vector control with 120V I/O. The PowerFlex 700 platform also supports configurable motor-control functions appropriate to different industrial applications.

4. Does the drive have an internal brake resistor?
No. The 20BD248A0ANNAND0 is specified without an internal drive-mounted brake resistor and without a brake IGBT. External braking equipment may be required for applications with specific stopping or regenerative requirements.

5. Does this model include a communication module?
No internal communication module is included in this configuration. The drive should therefore be evaluated together with the intended control architecture when network communication is required.

6. Does the drive use motor feedback?
The specified configuration is without feedback. Its vector-control operation is therefore configured for applications that do not require an external motor-feedback device.

7. What should be checked if the drive experiences an overcurrent fault?
Inspect the mechanical load, motor condition, output wiring, acceleration settings, and motor parameters. Excessive load or incorrect configuration can cause the drive to reach its current protection limits.

8. What motor data should be entered during commissioning?
The actual motor nameplate should be used for applicable voltage, current, frequency, speed, and other required motor parameters. Accurate data is particularly important when configuring vector-control operation.

9. How should this drive be integrated with an existing PLC?
Because this configuration uses 120V I/O and does not include an internal communication module, the control system should be designed around the available hardwired I/O or an appropriate separately installed communication solution.

10. What should be verified before replacing an existing PowerFlex 700?
Check the complete catalog number, input voltage, output current, motor horsepower, duty rating, I/O voltage, control method, feedback requirements, communication architecture, braking requirements, enclosure, and installed options. Existing parameters should also be documented before removing the original drive.
