There are provided a positioning control method and a positioning control device, which enables high speed positioning with low power consumption without repeating two or more acceleration and deceleration operations during travel from an original position to a target position. There is also provided an electronic component mounting apparatus, which enables high speed positioning with low power consumption and enables mounting of electronic components in a short period of time. When a movable body is moved from the original position to the target position, there is set an operational passing position for avoiding a passing avoidance region, and driving of a drive unit having a smaller travel distance from the original position to a coordinate of the operational passing position is started later than driving start timing of a drive unit having a longer travel distance, from the original position to another coordinate of the operational passing position, by a specified period of time.

In a motor drive device having a plurality of driver units for driving motors and a command generator for giving a command to the driver units which are connected in serial communication, there is a communication section for setting up the communication formats corresponding to each of the driver units having different communication formats including data transmission speed from one another. Communication among the plurality of driver units with the respective communication formats and the command generator is carried out on a single serial bus.

Motor drive, motor drive control method, and component attaching device

There are provided a positioning-controlling apparatus and a positioning-controlling method in which a rotary encoder ( ) detects the Z phase before the subject ( ) is return to the origin which is the position of the Z phase detected by the linear encoder ( ). The driving mode of the servo motor ( ) is switched from rectangular waveform pulse driving to sine waveform pulse driving upon the detection of the Z phase by the rotary encoder ( ). The subject's moving direction for returning to the origin may be previously specified, and in which the detection of the ON state of the origin sensor ( ), the detection of the Z phase by the rotary encoder ( ), and the detection of the Z phase by the linear encoder ( ) are done in this order, while the subject ( ) is being moved in the above specified direction. Alternatively, the rotary encoder ( ) may detect the CS phase instead of the Z phase.

Positioning-controlling apparatus and positioning-controlling method, and part-mounting equipment and part-mounting method

A controlling method and apparatus for positioning a robot that can output an optimal speed instruction for controlling residual vibration after completion of a moving operation, achieve reduction in tact time for the moving operation, and shorten the length of setting time. The method is a controlling method for positioning a robot ( ) for performing a point-to-point moving operation comprising: performing a test operation to measure a frequency of a residual vibration that is stopped at a target position; measuring a magnitude of the residual vibration based on the frequency during each of different lengths of moving time for a predetermined moving distance to find a relationship between the length of moving time and the magnitude of the vibration; calculating a shortest moving time at which vibration magnitude is minimized; and performing the point-to-point operation for the calculated shortest moving time, thereby to position the robot ( ) at the target position.
