The 1336F-CWF50-AA-EN-HAS2 drive is an Allen-Bradley/Rockwell Automation 1336 PLUS 2 adjustable frequency drive. The drive has its input voltage rated between 500 Volts AC and 600 Volts AC. The 1336F-CWF50-AA-EN-HAS2, like other drives in the Allen-Bradley 1336 PLUS II family, supports a programmable output frequency in to modulate it around a set frequency rating. This function is facilitated by the traverse function which uses the maximum traverse setting, the P jump, and the traverse period parameters to achieve an inertia-compensated triangular waveform. The 1336F-CWF50-AA-EN-HAS2, like other Allen-Bradley 1336 PLUS 2 drives, contains the “run on power up” capability which allows the drive to continue running after a power outage. When power resumes, the 1336F-CWF50-AA-EN-HAS2 runs at the current commanded speed provided the non-stop, start, enable, and auxiliary signals are present. The “run on power up” feature is useful when the drive is being used to control applications that require minimal or no human intervention.

Additionally, the Allen-Bradley/Rockwell Automation 1336F-CWF50-AA-EN-HAS2 drive has a “loss select” parameter which dictates the drive’s response when the control signal fails. This parameter provides 5 choices for the programmers to choose from when the drive encounters a signal failure. The programmer may choose to set the drive so that once the control signal fails, the 1336F-CWF50-AA-EN-HAS2 faults and stops, then it goes down to the minimum speed and issues a warning, goes to its maximum speed and issues a warning, maintains its speed and issues a warning, or it goes to a preset speed and issues a warning. The Allen-Bradley 1336F-CWF50-AA-EN-HAS2 supports a programmer/controller with a digital port for its human-machine interface module.
