Main Features and Advantages
The ALLEN-BRADLEY 1201-HAS2 delivers localized programming and diagnostic capability that streamlines maintenance workflows for facilities operating legacy 1336 series drives.
Local programming without a laptop: The ALLEN-BRADLEY 1201-HAS2 places the complete parameter set of a 1336 drive behind a dedicated keypad and screen mounted at the equipment. Technicians modify acceleration times, current limits, and speed references in the field, eliminating the need to transport a programming cable and configured PC to each drive location. This self-contained approach reduces commissioning time and simplifies routine adjustments during mechanical run-in or process changes .
Fault diagnosis at the point of failure: When a 1336 drive trips, the ALLEN-BRADLEY 1201-HAS2 displays the fault code alongside operating values recorded at the moment of the trip. This immediate visibility enables technicians to distinguish between transient conditions requiring a simple reset and recurring faults demanding root-cause investigation. The ability to retrieve fault history directly from the module shortens the diagnostic loop on intermittent issues that might otherwise require repeated site visits .
Integrated operator controls: Beyond programming functions, the ALLEN-BRADLEY 1201-HAS2 operates as a local operator station with start and stop control plus an analog potentiometer for speed reference. This capability proves valuable during initial commissioning, mechanical testing, or as a fallback control method when the primary control system is unavailable. The physical keyboard provides tactile feedback and reliable operation in environments where touchscreens may be impractical .
Drive-powered simplicity: The ALLEN-BRADLEY 1201-HAS2 draws its 5 V DC operating power directly from the host drive‘s interface connector, requiring no additional power supply, fusing, or wiring. This design simplifies installation to a single seating action and eliminates potential wiring errors that could damage the module or drive .
