Title:
サーボモータの制御装置
Document Type and Number:
Japanese Patent JP7311348
Kind Code:
B2
Abstract:
To provide a servo motor controller that can quickly and effectively stop an industrial machine at a particular position even if operation speed is relatively low when a fixed position stop command is issued. The servo motor includes a speed comparison unit configured to compare speed at a time of a fixed position stop command with a first speed, a fixed position stop operation determination unit configured to determine an operation method at the time of the fixed position stop command, and a fixed position stop control unit configured to control the servo motor based on the determined operation method. When speed at the time of the fixed position stop command is higher than the first speed, the fixed position stop operation determination unit decelerates the speed to a second speed lower than the first speed and creates a move command for stopping at a target position based on an acceleration rate during deceleration or a predetermined acceleration rate and, when speed at the time of the fixed position stop command is lower than the first speed, decelerates the speed by a predetermined deceleration rate and creates a move command for stopping at a target stop position, and the fixed position stop control unit controls the servo motor based on the move command.
