SERVOMOTOR SPEED CONTROL
First Claim
1. A method for controlling a servomotor for driving a movable part of a machine, the method comprising:
- determining the coordinates of an acceleration and of a deceleration curve for each stage of a cycle of operation to move said part;
determining the maximum number of stages required to complete said cycle;
initiating the acceleration curve for the first stage of the cycle of operation; and
dynamically correcting the cycle of operation, at at least one intermediate point in the cycle, to initiate the deceleration curve appropriate to the stage, at a predetermined decision point, if production line parameters require a change to the operation cycle.

Abstract
A method for controlling a servomotor for driving a movable part of a machine, the method comprising: determining the coordinates of an acceleration and of a deceleration curve for each stage of a cycle of operation to move said part; determining the maximum number of stages required to complete said cycle; initiating the acceleration curve for the first stage of the cycle of operation; and dynamically correcting the cycle of operation, at at least one intermediate point in the cycle, to initiate the deceleration curve appropriate to the stage, at a predetermined decision point, if production line parameters require a change to the operation cycle.

6. Control means for controlling a servomotor driving a movable part of a machine, the control means comprising:
-
means for determining the coordinates of an acceleration curve and a deceleration curve, for each stage of a cycle of operation to move said part; means for determining the maximum number of stages required to complete said cycle; means for initiating the acceleration curve for the first stage of the cycle of operation; and means for dynamically correcting the cycle of operation, at at least one intermediate point in the cycle, to initiate the deceleration curve appropriate to the stage, at a predetermined decision point, if production line parameters require early termination of the operation cycle. - View Dependent Claims (7, 8, 9, 10)
