Allen Bradley 20BC260A0ANNANC0 PowerFlex 700

FAQ

Q1: What is the Allen-Bradley 20BC260A0ANNANC0 PowerFlex 700 AC Drive?

A: The Allen-Bradley 20BC260A0ANNANC0 is a PowerFlex 700 AC Drive designed for industrial AC motor speed and torque control. It has a rated continuous output current of 260 A, a normal-duty power rating of 132 kW, and a heavy-duty power rating of 110 kW, according to the supplied specifications. It supports V/Hz, Sensorless Vector, and Vector Control, making it suitable for various industrial motor-control applications. Before installation, verify the drive’s nameplate ratings and configuration against the motor and machine requirements.

Q2: What are the input voltage and output power ratings of the 20BC260A0ANNANC0?

A: The supplied specifications list a nominal input voltage of 400 VAC and an allowable input range of 380–480 VAC, with three-phase input at 50 Hz. The input current is approximately 255 A, and the input power is approximately 177 kVA at 400 VAC. The drive provides 260 A continuous output current, with normal-duty and heavy-duty power ratings of 132 kW and 110 kW, respectively. These values should be checked against the motor’s rated current, load characteristics, and supply requirements to ensure proper application sizing.

Q3: Which motor-control modes and performance features does this drive support?

A: The 20BC260A0ANNANC0 is specified to support V/Hz, Sensorless Vector, and Vector Control. V/Hz control is commonly used for applications such as pumps and fans, while Sensorless Vector and Vector Control can provide improved torque response for more demanding loads. The supplied specifications list speed regulation of approximately 0.1% of base speed in Vector Control mode without feedback and torque regulation of approximately ±5% without feedback. Actual performance depends on the motor, control mode, parameter settings, and operating conditions.

Q4: What communication and control interfaces are available on the 20BC260A0ANNANC0?

A: The supplied specifications indicate that this model has no communication module and no human interface module, with a blank plate installed in place of the HIM. Its control I/O includes two analog inputs, two analog outputs, and six digital inputs and three digital outputs. The listed control method uses 24V DC I/O. If network communication or a local operator interface is required, confirm the compatible optional modules, accessories, and configuration before purchasing or integrating the drive into an existing automation system.

Q5: Does the 20BC260A0ANNANC0 include a braking IGBT or internal braking resistor?

A: No. According to the supplied specifications, this model does not include a braking IGBT or an internal braking resistor. Applications requiring rapid deceleration or frequent stopping may need an external braking solution, provided that the proposed components are compatible with the drive. Braking requirements depend on the motor’s inertia, load characteristics, deceleration time, and operating cycle. Verify the manufacturer’s recommendations before selecting braking components or modifying the installation.

Q6: What protection and operating features does the 20BC260A0ANNANC0 provide?

A: The supplied specifications list Class 10 motor overload protection, an EMC filter with common-mode choke, conformal coating, and a short-circuit rating of up to 200,000 A symmetrical. The drive also supports programmable acceleration and deceleration times from 0 to 3600 seconds and multiple stop modes, including Coast, DC Brake, Fast Brake, Ramp-to-Hold, and S-Curve. These functions can help support different machine operating requirements. Actual protection depends on correct installation, upstream protective devices, configuration, and adherence to the manufacturer’s instructions.

Q7: What are the dimensions, weight, and environmental requirements of the 20BC260A0ANNANC0?

A: The supplied dimensions are 976.3 × 403.9 × 275.5 mm, and the listed weight is 71.44 kg. The enclosure rating is IP20 / NEMA/UL Type 1. The specified power ride-through is approximately 15 ms at full load. When planning installation, allow sufficient cabinet space and airflow, confirm mounting requirements, and ensure that the electrical enclosure provides suitable environmental protection. Because of the unit’s size and weight, appropriate lifting and handling equipment should be used during installation.

Q8: What should buyers know before purchasing the Allen-Bradley 20BC260A0ANNANC0?

A: Buyers should verify the complete catalog number, electrical ratings, duty rating, control options, I/O configuration, communication requirements, braking configuration, and physical dimensions. For replacement projects, compare the existing drive’s specifications and installed options with those of the proposed unit before ordering. The product listing identifies the condition as New & In Stock, and the listed payment methods are T/T (Telegraphic Transfer) and Western Union. Confirm current availability, warranty coverage, included accessories, delivery arrangements, and final payment terms with the supplier before completing the purchase.
