The Danaher/American Precision Industries P51X-DO is a microprocessor-based power drive indexer engineered for precision motion control and stepper motor applications. This self-contained unit delivers programmable motion control through an English-like ICL (Intelli-Command Language), offering five programmable inputs and three programmable outputs for flexible external device integration. The P51X-DO incorporates encoder feedback for position monitoring, automatic ramping routines with user control, and battery-backed user memory for retained programming. Communications occur via RS-232C serial interface at up to 19,200 Baud, enabling host system integration.
