FAQ
FAQ
Q1: What is the Allen-Bradley 20BR125A3ANNACC1?
A: The 20BR125A3ANNACC1 is an Allen-Bradley PowerFlex 700 variable frequency drive designed for industrial motor speed and torque control. It uses a DC bus input and supports vector control.
Q2: What are the input voltage and output current ratings?
A: The drive uses a nominal 650 V DC input with precharge and has a 125 A normal-duty output rating. Confirm the applicable current and overload ratings against the drive nameplate and technical documentation.
Q3: What motor power does this model support?
A: Its catalog-family ratings are 100 HP (approximately 75 kW) for normal duty and 75 HP (approximately 55 kW) for heavy duty. The actual motor selection must also account for rated current, load characteristics, and operating conditions.
Q4: Does the 20BR125A3ANNACC1 include encoder feedback?
A: Yes. The catalog configuration identifies a standard encoder feedback option. Verify the installed encoder interface and wiring requirements before commissioning.
Q5: Which communication interface does this drive use?
A: This configuration specifies a ControlNet coaxial DPI communication module. Confirm compatibility with the existing ControlNet network and controller hardware before integration.
Q6: Does this model include a braking IGBT or braking resistor?
A: No. The specified configuration does not include a braking IGBT or a drive-mounted braking resistor. If the application requires dynamic braking, evaluate compatible external braking equipment.
Q7: What are the dimensions and weight of this drive?
A: The exact drive-only dimensions and weight have not been confirmed for this complete catalog number. The IP54 standalone enclosure reference is 1574.8 × 609.6 × 450.7 mm, with a listed drive-and-packaging weight of 154.68 kg. These figures should not be substituted for verified drive-only measurements.
Q8: Is the 20BR125A3ANNACC1 still available?
A: The PowerFlex 700 Type 20B family was discontinued by Rockwell Automation. Remaining stock, repair services, and compatible replacement options may vary. Check the unit’s complete catalog number and installed options before sourcing a replacement.
