Open-Loop Stepping SystemSureStep open-loop stepping system includes four standard motors, a one-size-fits-all step motor drive and a power supply. With holding torques from 83-434 oz-in., in NEMA size 17, 23 or 34 frames, the motors handle a variety of automation applications. They operate on 2.8 A per phase (size 17 motor uses 2.0 A), produce high torque, and allow the motors to achieve the best torque-to-volume ratio. The drives operate any of the four standard motors and feature standard +5 VDC optically isolated logic inputs for interfacing with DirectLOGIC PLCs or other controllers/indexers. A nine-position DIP switch is used to set up the drive; no software or add-on resistors are required for configuration.
