Abstract: A positioning apparatus is provided that starts positioning control according to output of a positioning command in accordance with input of an external input signal from an external sensor. The positioning apparatus includes an external input unit, a timer unit that counts a period of time that starts when the external input signal is input to the external input unit, a memory that stores a setting timer value that is set, using a positioning control program, as delay time for delaying the start of the positioning control and positioning command data calculated by an arithmetic processing unit, and a positioning command output unit that output the positioning command on the basis of the positioning command data stored in the memory to a target to be controlled. The positioning command output unit outputs the positioning command when a count value of the timer unit agrees with the setting timer value retained in the memory.

Abstract: A position-command-pulse generation unit generates a position command pulse to be output to a motor driver by advancing an initial phase thereof by a phase indicated by initial phase information preset in a device. The initial phase information indicates an arbitrary phase in a period of a half cycle of a first pulse of the position command pulse.
