The Allen-Bradley 1397-B040R-FS2010-HA1-L11 drive is a regenerative DC drive that has been designed to control the speed and torque of induction DC motors in the safest way possible. This drive has been included in the 1397 series of Allen-Bradley DC drives and it has been manufactured and designed by Allen-Bradley/Rockwell Automation. This drive employs a voltage of 460 Volts AC, a frequency of 50 to 60 Hertz, and a horsepower output rating of 40 Horsepower. The additional features of the Allen-Bradley/Rockwell Automation 1397-B040R-FS2010-HA1-L11 regenerative DC drive are a field current regulator that is employed to maintain a voltage that is constant enough to provide safe and secure operations. It also comes with a programmer and controller with an analog pot and an I/O expansion cord. These features can be selected with the drive according to the requirements of the application process.

When attaching a motor to the Allen-Bradley/Rockwell Automation 1397-B040R-FS2010-HA1-L11 regenerative DC drive, the ratings of the devices must be checked to ensure that both are compatible. The DC motor needs to be installed according to its instructions and the drive must be attached securely, according to the directions. Cables should be kept as short as possible to avoid power loss. Both the motor and the drive need to be included in a ground system. The Allen-Bradley/Rockwell Automation 1397-B040R-FS2010-HA1-L11 regenerative DC drive comes with an open housing, enabling the users to choose a custom enclosure freely. It is recommended to choose an enclosure in accordance with the environmental conditions of the place where the drive is going to be installed.
