ABSTRACT:
In a servomechanism which includes a motor and performs positioning control and velocity control, based on a response of the motor when a step command is supplied in a condition where a load is applied to the motor, the value of the load is estimated, and the servo-gain of the servomechanism is automatically set in accordance with the estimated load value. Load inertia of the servomechanism is automatically calculated, an optimum gain is automatically set based on the calculation result, and a test operation is performed, so that a time period required for the adjustment can be shortened.
