<P>PROBLEM TO BE SOLVED: To provide an operation control unit of a cargo handling machine that accurately performs displacement and positioning of a cargo with pulse control using positioning controllable motors such as servo motors for a drive motor. <P>SOLUTION: The operation control unit of a cargo handling machine includes the positioning controllable drive motor (servo motor SM), a drive amplifier (servo amplifier 3) to drive the drive motor, a controller (2), and an operation unit. The operation unit has a manual operation section that operates the number of generated pulses of a manual pulse generator (12) or a pulse generator and a demand switch (23). The controller inputs in the drive amplifier a pulse signal as effective from the pulse generator operated by the manual pulse generator or the manual operation section while the demand switch is turned ON, and the drive amplifier drives the drive motor so that the speed and displacement become proportional to the number of pulse signals. <P>COPYRIGHT: (C)2012,JPO&INPIT |
