Abstract:
A drive controller includes a speed compensation unit that performs a speed compensation for an object based on a result of comparison made by a speed comparator that compares a current speed of the drive object with a speed indicated by a speed command. The speed compensation unit includes a position-information-based speed gain setting unit that sets a position-information-based variable gain based on position-information-based speed gain information representing a relationship between a position of the object and position-information-based variable gain that varies depending on a load torque of the motor when the object is present at a predetermined position, and a speed compensation processor that performs a speed compensation based on a result of the comparison in the speed comparator and the position-information-based variable gain set by the position-information-based speed gain setting unit.
