FAQ
FAQ
Q1: What is the Allen-Bradley 20BD248A3ANNANC0?
A: The 20BD248A3ANNANC0 is identified as a PowerFlex 700 AC drive model. It belongs to the 480V industrial drive family designed for variable-speed control of three-phase AC motors.
Q2: What are the input voltage and output current ratings?
A: The corresponding 248 A PowerFlex 700 configuration uses a 480 VAC, three-phase supply and provides 248 A continuous output current. Verify the complete catalog number and nameplate before connecting the drive.
Q3: What motor power ratings does this drive support?
A: The corresponding 248 A configuration is rated at 200 HP for normal-duty operation and 150 HP for heavy-duty operation. The final selection should match the motor nameplate and application load.
Q4: What are the dimensions and weight of this model?
A: The corresponding Frame 6 drive has reference dimensions of approximately 976.3 × 403.9 × 275.5 mm (H × W × D) and a reference weight of approximately 71.44 kg. Confirm these values against the exact unit’s mechanical drawing before installation.
Q5: Does this model include a built-in braking resistor?
A: The corresponding standard configuration does not include an internal braking resistor or braking IGBT. An external braking solution may be required for applications involving frequent or rapid deceleration.
Q6: What control methods are available on the PowerFlex 700 series?
A: The series supports vector control, sensorless vector control and programmable V/Hz control, depending on the installed control configuration. The appropriate method depends on the motor and required operating performance.
Q7: How can the drive be integrated into an existing automation system?
A: Integration depends on the installed communication module and control I/O options. Check the full catalog number and hardware configuration before selecting a network interface or planning PLC communications.
Q8: Is the Allen-Bradley 20BD248A3ANNANC0 still available?
A: The PowerFlex 700 20B series has been discontinued. Remaining stock and refurbished units may be available from industrial automation suppliers. Confirm the exact catalog number, condition, warranty and replacement compatibility before purchase.
