Allen Bradley 20BC325N3ANNNNC0 PowerFlex 700

FAQ

Q1: What is the Allen-Bradley 20BC325N3ANNNNC0 AC drive?

A: The Allen-Bradley 20BC325N3ANNNNC0 is part of the PowerFlex 700 AC drive series, designed to regulate the speed and torque of compatible three-phase AC motors. It is suitable for industrial applications such as pumps, fans, conveyors, and other motor-driven machinery requiring variable-speed control.

Q2: What are the electrical ratings of this PowerFlex 700 drive?

A: This model is specified for a 400 V AC three-phase supply, with a rated continuous output current of 325 A. Both normal-duty and heavy-duty power ratings are listed as 180 kW. Before installation, verify the motor nameplate current, supply conditions, and application load to ensure the drive is correctly sized.

Q3: What are the dimensions and weight of the 20BC325N3ANNNNC0?

A: The specified dimensions are 1447.8 × 509.3 × 409.3 mm (H × W × D), and the weight is 147 kg. Allow additional cabinet space for wiring, ventilation, installation clearances, and maintenance access. Confirm the dimensions against the manufacturer’s documentation for the exact flange-mount configuration before designing the enclosure.

Q4: Does this drive include a keypad and display?

A: Yes. According to the supplied specifications, this configuration includes an LCD display with a full numeric keypad. The operator interface can be used for local parameter configuration, monitoring, and troubleshooting. The exact interface features and supported functions should be confirmed against the installed HIM version.

Q5: What control and feedback features does this model support?

A: The drive uses vector control and provides 24 V DC control I/O. It is specified without a feedback option, so confirm that its sensorless control capabilities meet the application’s speed regulation and torque requirements. Applications requiring encoder-based closed-loop control may need a different configuration.

Q6: Does the 20BC325N3ANNNNC0 support network communication?

A: The supplied specifications list no communication module. Therefore, a DeviceNet, EtherNet/IP, or other network interface should not be assumed to be included. If integration with a PLC or industrial network is required, verify the compatible communication options and any additional hardware needed for the exact catalog number.

Q7: Does this drive include braking hardware or an EMC filter?

A: No. The listed configuration has no braking IGBT, no drive-mounted braking resistor, and no CE-compliant EMC filter. If the application requires rapid deceleration, braking-energy management, or additional electromagnetic compatibility measures, suitable external components may be necessary. These should be selected according to the application and applicable electrical standards.

Q8: What installation precautions should be considered?

A: This model is specified as an open / flange-mount drive with forced-air cooling. It should be installed in a properly designed cabinet or panel that provides suitable environmental protection, airflow, electrical clearances, and structural support for its 147 kg weight. Before ordering, verify the complete catalog number, enclosure arrangement, included accessories, condition, and current availability with the supplier.
