Problems solved by technology

[0006] As described in Patent Document 1, in the method of giving a delay time after the position deviation enters the positioning end range, the time itself when the position deviation enters the positioning end range varies due to the deviation of the device, so the positioning end output is sent There is also a deviation in the time of the positioning, and there is also the problem of unstable determination of the positioning end

Embodiment approach

[0016] figure 1 It is a block diagram of the motor drive device in embodiment of this invention. Such as figure 1 As shown, the motor drive device 100 is connected to the motor 20 for driving the motor 20 . As is generally known, the drive motor 20 includes, for example, a stator having a driving coil and a mover having a permanent magnet. A voltage is applied to the coil of the motor 20 to pass an electric current and move the mover. The motor drive device 100 has a position control function of moving the position of the mover to a predetermined position. In order to realize this function, a position detector 21 is installed in the motor 20 . The position detector 21 detects the position of the mover of the motor 20 , and supplies the detected position to the motor drive device 100 as a motor position signal 10 . In addition, the position command value 11 is notified to the motor drive device 100 from, for example, the external main controller 22 or the like. The moto...

Abstract

The present invention provides a motor driving device which is used for performing position control for the motor that is provided with a position detector. The motor driving device comprises the following components: a storage part which stores a positioning finishing amplitude and positioning determination delay time; a determination starting signal output part which generates and outputs a determination starting signal according to a position offset between a motor position signal from the position detector and a position instruction value and the positioning determination delay time; and a positioning finishing signal output part which generates and outputs a positioning finishing signal according to the position instruction value, the motor position signal, the positioning finishing amplitude and the determination starting signal. Furthermore, the positioning finishing signal output part outputs the determination starting signal when the positioning determination delay time is passed after the position indication value is changed to zero. Furthermore, the positioning finishing signal output part only outputs the positioning finishing signal at a state that the position offset is within the positioning finishing amplitude after the determination starting signal is input.

Description

technical field [0001] The present invention relates to a motor drive device having a positioning completion judging function for judging that a motor has reached a target position. Background technique [0002] In semiconductor-related devices, electronic component mounting machines, and the like, high-speed responsiveness is very important, and in particular, shortening of positioning adjustment time, which is an index of trackability to position commands, is required. Generally, in a device that controls a motor such as a servo amplifier, if the deviation of the motor position relative to the target position (hereinafter, referred to as the position deviation as appropriate) is below the adjustment range, it is judged that the target position has been reached, and the positioning signal is output. end signal. The main controller confirms that the positioning completion signal has been output, and starts the next operation. Especially for axes that are operated in conjun...
