Description

The Allen-Bradley 20G1AND248AN0NNNNN is a PowerFlex 755 adjustable frequency AC drive designed for variable-speed and high-performance motor control.

Configured for 480V AC input, this Frame 6 drive provides 248 A continuous output under Normal Duty operation. It is rated for 200 Hp Normal Duty and 150 Hp Heavy Duty applications.

The PowerFlex 755 platform combines embedded EtherNet/IP, integrated DeviceLogix control, predictive diagnostics, and selectable motor control algorithms. It provides speed, position, and torque control with Vector Control with Force Technology, Permanent Magnet Motor Control, sensorless control, and Volts-per-Hertz operation.

This catalog configuration uses a six-pulse input without DC terminals and an IP00 open enclosure. Filtering is provided with the default common-mode capacitor jumper removed. The configured drive has no internal dynamic brake resistor or internal brake transistor.

Installation Guidelines

1. Verify the drive configuration. Confirm the catalog number, input voltage, frame size, enclosure type, and motor rating before installation.
2. Mount the drive securely. Install the drive in a suitable control enclosure or mounting location with adequate ventilation and service access.
3. Connect power and motor wiring. Verify incoming supply voltage and connect the motor according to the applicable PowerFlex 755 wiring documentation.
4. Establish protective grounding. Bond the drive and associated equipment to the control system grounding network before energizing the unit.
5. Configure communication. Connect the embedded EtherNet/IP interface when network integration is required and assign the appropriate network settings.
6. Set the motor and control parameters. Enter the motor nameplate information and select the required control method for the application.
7. Perform commissioning checks. Verify wiring, motor direction, operating commands, speed reference, fault status, and application response before normal operation.
