Abstract
A dynamic optimization method for speed data, for compensating for a speed data maximum value and a minimum resolution that can be specified by users without depending on a speed pattern preparation cycle. A dynamic optimizing method for speed data used for preparing a speed instruction pattern fed to a motor in a positioning device, wherein a speed pattern generator (1) that calculates a desired speed pattern when a moving instruction (2) such as a moving distance, speed, acceleration time and deceleration time is input is provided, and a speed pattern preparation cycle (3) can be specified by users without the possibility that speed data maximum value and a minimum resolution of speed data are modified.
Claims3
A dynamic optimizing method for speed data used for preparing a speed instruction pattern fed to a servo motor in a positioning device, comprising:
- calculating a desired speed pattern when a moving distance, speed, acceleration time and deceleration time are inputted;
- and
- specifying a speed pattern preparation cycle by a user and shifting a decimal part of the speed data right or left to prevent a maximum value of the speed data and a minimum resolution of the speed data from being changed.
A positioning device using a servo motor, comprising:
- a moving instruction input unit inputting a moving instruction;
- a speed pattern preparation cycle unit inputting a speed pattern preparation cycle specified by a user and shifting a decimal part of the speed data right or left to prevent a maximum value of speed data and a minimum resolution of the speed data from being changed;
- a speed pattern preparation unit preparing a speed instruction pattern based on the moving instruction, the speed data, and the speed pattern preparation cycle;
- a speed instruction unit outputting a speed instruction per cycle based on the speed instruction pattern from the speed pattern preparation unit;
- and
- a servo control unit driving the servo motor based on the speed instruction from the speed instruction unit.
