Product Description:

The OSP-700B monitor is produced by Okuma for the OSP CNC Monitors series. Designed as the primary operator interface on OSP-controlled machine tools, it combines display functions, program media handling, and serial communication in a single panel. The unit shows NC status and part programs, accepts external tape input, and links to host computers, making it a central element for program loading, editing, and real-time machining feedback in industrial automation environments.

The panel houses a photoelectric tape reader with a capacity of 1840 M for 2DD cassettes and 3770 M for 2HD media, allowing large NC programs to be read from punched tape. A built-in 3.5-inch floppy drive adds removable storage for smaller files. Data is displayed on a monochrome STN LCD that maintains readability under shop lighting while keeping power draw low. Four independent serial ports support DNC and peripheral links, and the control has 4 RS-232C channels that can be assigned to tooling presetters, bar feeders, or PCs. All functions are arranged on a vertical panel so the monitor can mount directly inside the machine enclosure without depth interference.

Program retention is handled in solid-state memory blocks that provide a maximum of 10240 M and working space for 24,000 characters, so lengthy machining cycles can remain in the control without external media. File management uses a main name length of 16 characters and a three-character extension, which fits standard OSP naming conventions. During drip-feed or data upload, the serial interface transmits using a framing pattern of 1 start, 8 data, 1 parity, and 2 stop, matching common CNC host settings. When punched tape is used, the reader advances at 270 characters per second, which helps reduce wait time before execution. Thirteen spindle override steps are available for fine speed adjustment during prove-out, allowing repeatable spindle changes during operation.
