Allen Bradley 20BC260A3ANNAND0 PowerFlex 700

FAQ

Q1: What is the Allen-Bradley 20BC260A3ANNAND0?

A: The Allen-Bradley 20BC260A3ANNAND0 is a PowerFlex 700 AC drive intended for controlling the speed and torque of three-phase AC motors in industrial applications. The PowerFlex 700 family supports multiple motor-control methods, including V/Hz and vector-based control. The drive’s suitability depends on the motor’s current rating, load characteristics, supply voltage, and required control performance. Confirm the complete catalog number and nameplate before installation or replacement.

Q2: What are the voltage and power ratings of this model?

A: The working specification provided for this model lists a nominal input voltage of 400 VAC, a supply range of 380–480 VAC, an input current of 255 A, and input power of 177 kVA at 400 VAC. The listed continuous output current is 260 A, with ratings of 132 kW for normal-duty operation and 110 kW for heavy-duty operation. These values should be checked against the manufacturer’s documentation for the exact catalog number, particularly when sizing the drive for a replacement motor or an existing installation.

Q3: Which motor-control modes are available?

A: The PowerFlex 700 series supports V/Hz, Sensorless Vector, and Vector Control, depending on the installed configuration and applicable product specifications. V/Hz control is commonly used for general-purpose variable-speed applications, while vector control can provide more precise speed and torque regulation. The supplied data lists speed regulation of 0.1% of base speed and torque regulation of ±5% without feedback. Verify that these performance figures apply to the exact drive configuration and intended operating mode.

Q4: What control I/O voltage does the 20BC260A3ANNAND0 use?

A: The control I/O voltage is an important detail to verify for this catalog number. The supplied specifications list 115V AC I/O, but other PowerFlex 700 variants use different control I/O configurations. Before connecting external switches, sensors, PLC outputs, or control relays, check the drive’s wiring diagram and terminal ratings. Using an incompatible control voltage can damage equipment or create unsafe operating conditions.

Q5: Does the drive include a communication module or motor feedback device?

A: The exact communication module for the 20BC260A3ANNAND0 should be confirmed from its nameplate, installed options, or product documentation. Communication hardware can differ among PowerFlex 700 catalog variants, so a module fitted to a similar model should not automatically be assumed to be present. The supplied data also indicates no feedback device. If the application requires encoder-based closed-loop control or a specific industrial network, verify the necessary hardware and compatibility before purchasing.

Q6: Does this model include a braking resistor?

A: The supplied specification lists no brake IGBT and no internal braking resistor. The drive may support programmable stopping functions, but these are not equivalent to having a complete dynamic braking system. Applications with high-inertia loads, frequent deceleration, or short stopping times may require an appropriately selected external braking solution. Confirm the drive’s braking capabilities and the manufacturer’s installation requirements before adding external components.

Q7: What are the dimensions and environmental requirements?

A: The listed dimensions are 976.3 × 403.9 × 275.5 mm, and the weight is 71.44 kg. The enclosure rating is IP20 / NEMA/UL Type 1. The supplied operating conditions are 0–50 °C, relative humidity of 5–95% without condensation, and an installation altitude of up to 1000 m without derating. Ensure that the enclosure, ventilation, mounting structure, and cable access are suitable for the installation. Confirm the dimensions and weight against the actual unit before preparing a replacement or cabinet layout.

Q8: What should buyers verify before ordering the 20BC260A3ANNAND0?

A: Buyers should verify the full catalog number, input voltage, output current, duty rating, control I/O voltage, communication options, keypad configuration, feedback requirements, and braking hardware. Physical dimensions and weight should also be checked if the drive is intended to replace an existing unit. Because options can vary across similar PowerFlex 700 models, request a nameplate photo or manufacturer documentation if any configuration details are uncertain. The listing can specify new and in-stock condition and T/T or Western Union payment, but stock status, warranty, and delivery time should be confirmed with the supplier.
