Abstract
A synchronous controller that can perform high-speed, high-accuracy torque constant control even in applications wherein rapid load variation exists. The torque amount used for a control purpose of pressing a workpiece, etc., can be set as a torque offset correction amount and the torque offset correction amount is added to a torque command generated based on a speed command and speed feedback generated based on a position command and positions feedback.
Claims7
A synchronous controller comprising:
- a speed control section for generating a torque command based on a speed command and a speed feedback value derived from a position command and a position feedback value, said speed control section being placed on a second main shaft side of a torque constant control system,
- wherein a first main shaft side of said torque constant control system fixes one side of a workpiece and controls rotation and the second main shaft side presses and holds an opposite side of the workpiece, and
- wherein a torque amount used to control the pressing of the workpiece is set as a torque offset correction amount, and the torque offset correction amount is added to the torque command.
