Abstract: A moving-body monitoring device has a position detection unit that outputs positional information of a moving body, a proximity sensor that detects the moving body, a first storage unit that stores a position when the moving body having moved in a first direction is detected as first positional information, and stores a position when the moving body having moved in a second direction is detected as second positional information, and a calculation unit that calculates a fixed-point position of a detecting region of the proximity sensor during monitoring as fixed-point positional information based on the first and second positional information. The device also has a second storage unit that stores reference fixed-point positional information, and a monitoring unit that, when a deviation between the fixed-point and reference fixed-point positional information goes beyond a stipulated range, determines that a positional deviation amount of the moving body exceeds a tolerance.

Abstract: A control apparatus records commands and information about execution time of industrial machinery. The control apparatus analyzes a program, and when a command that requires preparation time exists in the program, then calculates advanced preview command time by subtracting the preparation time from time to start the execution of the command based on the execution time previously recorded. The control apparatus outputs in advance the command requiring the preparation time when the advanced preview command time comes, so as to shorten the preparation time.

Abstract: A controller of a rotary axis includes: a storage unit that stores data of a braking distance for each rotation number of the rotary axis and provides a current braking distance S3 corresponding to a current rotation number of the rotary axis; and a deceleration command calculating unit that calculates a speed command V2 of the rotary axis on a basis of the remaining movement amount S2 and the current braking distance S3; in which the deceleration command calculating unit maintains the current rotation number of the rotary axis in a case in which a difference S4 between the remaining movement amount S2 and the current braking distance S3 is equal to or greater than a predetermined value, and starts deceleration of the rotary axis in a case in which the difference S4 is less than the predetermined value.
