1 Catalog 8-2/US S, SX & SXF Systems The S Family of drives and drive/indexer systems are standalone, packaged microstepping systems. Designed for reliability, the S step and direction input drive, the SX drive/indexer, and the SXF drive/indexer with encoder following, all offer top quality performance. Both the SX and SXF utilize Compumotor s latest X-language enhancements and are easily programmed over an RS-232C interface. These products can perform registration moves, and they are also equipped to provide complex move profiling. Common Features Performance s from 65 to 1,9 oz-in Speeds to 5 rps (3, rpm) continuous 16 user selectable motor resolutions to 5,8 steps/rev Three-state current control for reduced motor heating User-selectable current waveform for smooth operation Zero phase input resets phase currents to the power up positions Fault output for remote signalling and diagnostics Optically isolated step and direction, shutdown and zero phase inputs nti-resonance eliminates mid-range instability Protection Safety interlock in the motor connector to prevent connector damage if connector is removed with power applied Fully short circuit protected phase-to-phase and phase-toground with no time limit Enclosed to prevent contaminants from entering the drive enclosure dump circuitry protects the drive from large inertial loads Interface Capability RP24 remote panel interface, see page C119 Physical Nine motors with 1 foot motor cables. vailable in 23, 34 and 42 frame sizes status indicators; power, step input, undervoltage, overvoltage and motor fault The S The Compumotor optically isolated step and direction interface is provided, allowing Host Computer or Programmable Controller High Level Commands the S to connect to any Compumotor indexer or the user's pulse train.
