FAQ
Q1: What is the Allen-Bradley 20BC730A0ANNNNC0 AC drive?
A: The Allen-Bradley 20BC730A0ANNNNC0 belongs to the PowerFlex 700 family of variable frequency AC drives. It is designed to regulate the speed and torque of industrial three-phase AC motors. Its high-current design makes it suitable for large motor applications, including pumps, fans, conveyors, and heavy industrial equipment, provided the drive is correctly sized for the motor and load.
Q2: What are the current and power ratings of this model?
A: The supplied specifications list a rated output current of 730 A, a normal-duty power rating of 400 kW, and a heavy-duty power rating of 500 kW. Because the listed heavy-duty rating is higher than the normal-duty rating, these values should be checked against the official Rockwell Automation documentation for the exact catalog number before use. Do not select the drive based on power ratings alone; verify motor current and overload requirements.
Q3: What are the dimensions and weight of the 20BC730A0ANNNNC0?
A: The specified dimensions are 2349.1 × 549.7 × 757.9 mm (H × W × D), and the listed weight is 526 kg. Installation planning should account for the drive’s substantial mass, roll-in mounting arrangement, ventilation requirements, cable access, and maintenance clearances. Confirm the manufacturer’s dimensional drawing before designing the cabinet or arranging transport and lifting equipment.
Q4: What control functions does this PowerFlex 700 drive support?
A: This configuration is specified with vector control, independently programmable acceleration and deceleration, electronic motor overload protection, and programmable current limiting. These functions help manage motor speed, torque, and operating limits. The appropriate settings depend on the motor nameplate, load characteristics, and application requirements.
Q5: What is the maximum output frequency?
A: The supplied specifications list an output frequency of up to 420 Hz. The achievable frequency depends on the selected control mode, drive configuration, motor characteristics, and applicable operating limits. Confirm that the connected motor and driven equipment are suitable for the intended operating frequency.
Q6: Does the drive include a keypad or communication module?
A: No. The listed configuration has no HIM and uses a blank plate; it also has no internal communication module. A compatible operator interface may be required for local programming and diagnostics, while PLC or network integration may require additional compatible hardware. Verify the exact catalog configuration before ordering accessories.
Q7: Does the 20BC730A0ANNNNC0 include braking hardware or an EMC filter?
A: The supplied specifications indicate that the drive does not include a brake IGBT, drive-mounted braking resistor, or CE-compliant EMC filter. If the application requires rapid deceleration, braking-energy management, or additional electromagnetic compatibility measures, external components may be required. These should be selected according to the motor, load inertia, installation environment, and applicable electrical standards.
Q8: What installation precautions should be considered before purchasing?
A: This model is specified with an IP00 open-type enclosure and roll-in mounting. It requires a suitably protected electrical installation area, adequate forced-air cooling, appropriate electrical clearances, and sufficient structural support for its 526 kg weight. The PowerFlex 700 is an older product family, so confirm current availability, unit condition, complete catalog number, included options, and warranty with the supplier before purchasing.
