Introduction

The Allen-Bradley 20F1AND248JA0NNNNN is a PowerFlex 753 AC drive designed for high-power industrial motor applications. It combines embedded I/O, forced-air cooling, and configurable drive functions in a Frame 6 platform.

This configuration operates on a 480 V AC three-phase supply and provides a rated output current of 248 A. Its power ratings are 200 HP under normal-duty conditions and 150 HP under heavy-duty conditions. The drive also includes a dynamic braking transistor and a filtered configuration with the common-mode capacitor jumper installed.

Supplied without a local Human Interface Module, the unit can be incorporated into systems where drive monitoring and parameter management are handled through a PLC, network interface, or separately selected operator terminal. It is suitable for industrial installations that require high-capacity motor control and flexible automation integration.

Applications

The Allen-Bradley PowerFlex 753 20F1AND248JA0NNNNN is a high-capacity variable-frequency AC drive designed for industrial motor-control systems. With a 248 A output rating and a Frame 6 configuration, it is suitable for large motors used in demanding production and process environments.

Typical applications include:

Large industrial pumps and water-treatment systems
Fans, blowers, and ventilation equipment
Heavy-duty conveyor and material-handling systems
Mixers, agitators, and process machinery
Manufacturing and automated production lines
Industrial equipment requiring adjustable motor speed and controlled acceleration

The drive's embedded I/O and configurable communication options make it suitable for integration into PLC-based automation systems.

Advantages

High output capacity

The 248 A output rating supports substantial motor loads, with separate normal-duty and heavy-duty ratings to accommodate different operating requirements.

Embedded I/O

Built-in I/O provides connections for supported control signals, helping simplify integration with external devices and automation equipment.

Dynamic braking transistor

This catalog configuration includes an internal dynamic braking transistor. An appropriately selected external braking resistor can be used when the application requires additional braking capability.

Forced-air cooling

The air-cooled design uses forced ventilation to manage heat during operation. Proper cabinet airflow and installation clearances are important for maintaining reliable performance.

Integrated filtering configuration

The drive is supplied with filtering and the common-mode capacitor jumper installed, providing a defined EMC configuration for suitable installations.

Flexible system integration

As part of the PowerFlex 750 family, the drive supports optional communication and feedback modules for applications with additional control or network requirements.

Technical FAQs

Q1: What is the rated output current of the 20F1AND248JA0NNNNN?

The rated output current is 248 A. The applicable motor rating depends on the selected operating duty and the motor's electrical characteristics.

Q2: What is the input voltage requirement?

This model is designed for a 480 V AC, three-phase power system. The supply voltage and protection arrangement should comply with the manufacturer's installation requirements.

Q3: What are the normal-duty and heavy-duty power ratings?

The drive is rated at 200 HP for normal-duty operation and 150 HP for heavy-duty operation. The correct rating should be selected according to the load profile and application requirements.

Q4: What does Frame 6 mean for this drive?

Frame 6 identifies the drive's physical and power-frame class within the PowerFlex 750 family. It is relevant when checking cabinet space, mounting arrangements, cooling, and compatible accessories.

Q5: Does this catalog configuration include dynamic braking?

Yes. The JA configuration includes a dynamic braking transistor. An external braking resistor may be needed, depending on the motor's deceleration requirements and regenerated energy.

Q6: Is a Human Interface Module included?

No. This configuration is supplied with a blank HIM opening. A compatible Human Interface Module can be selected separately if local parameter access and operation are required.

Q7: Does the drive include embedded I/O?

Yes. Embedded I/O is part of the PowerFlex 753 platform and supports connection to compatible external control signals and devices.

Q8: What cooling method does this model use?

It uses forced-air cooling. The installation must provide adequate ventilation and comply with the recommended airflow and clearance requirements.

Q9: Can the drive be connected to an EtherNet/IP control network?

Yes. The PowerFlex 753 supports EtherNet/IP through compatible communication option modules. The required module should be selected to match the PLC and network architecture.

Q10: What should be checked before commissioning this drive?

Verify the incoming supply, motor nameplate data, duty rating, overload settings, grounding, braking resistor requirements, control wiring, communication configuration, and cooling conditions. Confirm the drive's complete catalog number and installed options before applying power.
