Abstract
A control method for a servomotor which is controlled by a control system with a position control loop and a speed control loop, such that a degree of flexibility specified on working coordinates, on which the servomotor is situated, is converted into servo gains Kp and Kv for individual axes of the servomotor, and the servomotor is driven according to the converted servo gains Kp and Kv, whereby the degree of flexibility can be set on the working coordinates, and a driven body can be moved manually.
Claims4
A flexible servocontrol method of a servomotor which drives a body, the servomotor being controlled by a control system including a position control loop and a speed control loop, the flexible servocontrol method comprising the steps of:
- specifying the degrees of flexibility on a working coordinate system of the body;
- converting the degrees of flexibility specified on the working coordinate system into servo gains with respect to individual axes of the servo motor;
- and
- driving the servo motor according to the converted gains so that the body which is normally driven by the servo motor can be moved manually.
