Monitoring data display device

摘要

An apparatus for displaying monitoring data of a continuously varying operation condition of a drive mechanism driven by an actuator, in which data of one operation cycle of the drive mechanism is detected preliminarily as reference data and displayed on a coordinate axis on a monitor to show deviation between the reference data and the detected data of each operation cycle. Allowable uppermost and lowermost limit data of the reference data are also calculated and displayed on the same coordinate axis of the displaying surface of the monitor.
