FAQ
FAQ
Q1: What is the Allen-Bradley 20BD248A3ANNANC1?
A: The 20BD248A3ANNANC1 is identified as a PowerFlex 700 adjustable frequency AC drive for industrial three-phase motor control. It is designed to regulate motor speed in applications requiring variable-speed operation.
Q2: What are the input voltage and output current ratings?
A: The corresponding drive configuration is rated for a 480 VAC, three-phase supply and 248 A continuous output current. Verify the product nameplate before connecting it to the power supply.
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 correct selection depends on the motor’s rated current and the application load.
Q4: What are the dimensions and weight of this model?
A: Reference dimensions for the corresponding Frame 6 drive are approximately 976.3 × 403.9 × 275.5 mm (H × W × D), with a reference weight of 71.44 kg (157.5 lb). Confirm the exact enclosure and 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. External braking equipment may be necessary for applications involving rapid deceleration.
Q6: What control methods does the PowerFlex 700 support?
A: The series supports vector control, sensorless vector control and programmable V/Hz control. The available functions depend on the installed control configuration and parameter settings.
Q7: Can this drive communicate with a PLC?
A: PLC integration depends on the communication hardware installed in the drive. Check the exact catalog number and communication module before selecting a network protocol or configuring the control system.
Q8: Is the Allen-Bradley 20BD248A3ANNANC1 still available?
A: The PowerFlex 700 20B series has been discontinued. Remaining inventory and refurbished units may be available from industrial automation suppliers. Confirm the catalog number, hardware options, condition and warranty before purchasing.
