Allen-Bradley 20F11ND022AA0NNNNN PowerFlex 753 Drive

Allen-Bradley 20F11ND022AA0NNNNN PowerFlex 753 AC Drive 22A 15HP

Product Introduction

The Allen-Bradley 20F11ND022AA0NNNNN belongs to the popular PowerFlex 753 series. This adjustable frequency drive provides precise motor speed control. It handles output currents up to 22 amps continuously. The unit operates on a 480V AC three-phase supply.

For instance, you can use this VFD for pumps and fans. Furthermore, it works excellently for conveyors and mixers. This model supports three control methods for maximum flexibility. Therefore, it adapts to both simple and complex applications.

Additionally, the PowerFlex 753 20F11ND022AA0NNNNN includes an internal brake transistor. You can add an external resistor for dynamic braking. The open-type enclosure mounts easily inside standard cabinets.

Technical Specifications

The 20F11ND022AA0NNNNN accepts three-phase input at 480V AC or 650V DC. Its normal duty power rating stands at 15 HP (11 kW). The heavy duty rating reaches 10 HP (7.5 kW) for tougher loads.

Key electrical parameters include:

• Output current: 22 amps continuous

• Overload capacity: 110% for 60 seconds

• Frequency range: 0 to 599 Hz

• Enclosure rating: IP20 / IP00 (open type)

• Frame size: Frame 2

Moreover, this drive comes with a built-in CM jumper removed. This configuration reduces common mode noise. The unit includes an AC input with precharge for reliable startup sequencing.

Control Methods and Performance

The PowerFlex 753 offers three distinct control methods. First, V/Hz control works well for fans and pumps. Second, vector control delivers excellent torque at low speeds. Third, sensorless vector control provides high performance without feedback devices.

Specifically, enhanced control algorithms improve motor efficiency. The drive includes embedded I/O for basic machine interface. Six digital inputs and two analog inputs come standard. Two relay outputs and one analog output are also provided.

Furthermore, this model has no HIM (human interface module) installed. You can add a remote HIM later for local programming. The drive also lacks communication modules. Optional modules add EtherNet/IP, ControlNet, or DeviceNet when needed.

Mechanical and Environmental Ratings

The Catalog Number 20F11ND022AA0NNNNN measures 200 mm wide, 350 mm high, and 200 mm deep. Its Frame 2 size fits many existing PowerFlex installations. The unit weighs 9.07 kg (20.00 lbs).

Environmental specifications suit industrial environments. Operating temperature ranges from 0°C to 50°C. Storage temperature extends from -40°C to 85°C. Humidity tolerance goes up to 95% without condensation.

Next, the maximum operating altitude is 1000 meters above sea level. For higher locations, derating becomes necessary. The air-cooled design provides effective thermal management. No external cooling fan is required for most applications.

Installation Guidelines

You should mount the Allen-Bradley PowerFlex 753 vertically on a flat panel. Leave 125 mm of free space above and below for airflow. Use M6 screws through the four mounting holes on the frame.

Furthermore, follow correct wiring procedures. Connect input power to terminals L1, L2, and L3. Connect the motor to terminals U, V, and W. Ground the unit using the dedicated grounding terminal. This reduces electrical noise and ensures safety.

Finally, set up basic parameters before starting the motor. Program motor nameplate values into parameters P031-P036. Configure acceleration and deceleration times in P041 and P042. Use a remote HIM or Connected Components Workbench software for programming.

Frequently Asked Questions (FAQ)

1. Can the 20F11ND022AA0NNNNN run on single-phase power?
No. This drive requires three-phase input only. Single-phase operation is not supported at 15HP rating.

2. What is the difference between ND and HD ratings?
ND (Normal Duty) is 15HP for variable torque loads like fans. HD (Heavy Duty) is 10HP for constant torque loads like conveyors.

3. Does this drive include a communication module?
No. The PowerFlex 753 20F11ND022AA0NNNNN has no built-in network module. You must add an optional card for Ethernet or fieldbus.

4. How do I program the drive without a HIM?
Use Connected Components Workbench software with a 1203-USB converter. Alternatively, purchase a remote HIM (20-HIM-C6S) separately.

5. Is the internal brake transistor ready to use?
Yes. The DB transistor is fully installed. You only need to add an external braking resistor across DC+ and DC- terminals.
