The Allen-Bradley 1336F-AQF20-AN-EN-LA4-L6E 1336 PLUS II series variable frequency drive or VFD is used in the automation industry to control variable speed motors. The frequency that the drive applies to these motors will produce changes in their speed and torque ratings. The frequency variation settings will be developed by the drive through a programming phase that needs to be completed before starting operations with the drive. The Allen-Bradley 1336F-AQF20-AN-EN-LA4-L6E variable frequency drive operates with AC or DC input voltage. Its input voltage ratings are 200 to 240 Volts AC (3-phase) at 50 to 60 Hertz and 310 Volts DC. The drive also supports a Horsepower output rating of 2 Horsepower. The 1336F-AQF20-AN-EN-LA4-L6E variable frequency drive comes with 4 status indicators that are located on the main control board.

The Allen-Bradley 1336F-AQF20-AN-EN-LA4-L6E 1336 PLUS II series variable frequency drive includes an open enclosure that makes it easy to mount and allows it to dissipate heat quickly. This drive must not come into contact with liquids or any corrosive materials. Its open enclosure does not provide it with protection against liquids, corrosive materials, and large quantities of dust. The Allen-Bradley 1336F-AQF20-AN-EN-LA4-L6E variable frequency drive comes with a DC cooling fan that helps to prevent overheating and to keep the drive operating with a stable internal temperature. This drive can be installed vertically and clearances must be left on each side of it for ventilation. The drive comes with senseless vector control technology and a variety of protective features such as undervoltage and overvoltage protection, and single-phase detection. The Allen-Bradley 1336F-AQF20-AN-EN-LA4-L6E variable frequency drive also uses multiple sensors to achieve dynamic current control.
