Abstract
An adaptive control device according to the present invention includes: a processor that generates a second command value for a motor on the basis of at least one of a first command value received from a numerical control device, feedback data received from a motor control device that controls the motor on the basis of the first command value, and sensor data received from a sensor; and a communication circuit that transmits the second command value to the numerical control device.
Claims18
A control device comprising:
- circuitry configured to generate a second command value for a motor on a basis of at least one of:
- a first command value received from a numerical controller;
- feedback data received from a motor controller that controls the motor on the basis of the first command value;
- and
- sensor data received from a sensor;
- a communication circuit to transmit the second command value to the numerical controller;
- and
- a signal relay circuit to allow the first command value transmitted from the numerical controller to pass therethrough to the motor controller without change to the first command value, and allow the feedback data transmitted from the motor controller to pass therethrough to the numerical controller without change to the feedback data, the signal relay circuit being connected to a communication line between the numerical controller and the motor controller.
