SERVO SYSTEM, DRIVE DEVICE FROM SERVOMOTOR, SAFETY DEVICE AND METHOD OF CONTROL SERVO SYSTEM

摘要

1. A servo system containing:! servomotor, a control device that transmits a control signal to control the operation of the servomotor,! a position sensor that recognizes the operation of the servo motor and transmits a feedback signal displaying the recognized operation,! a servo drive that generates a setpoint value for the servo motor by using a control signal received from a control device and a feedback signal received from a position sensor and drives a servo motor so that the servo motor matches the setpoint, and! a safety device that determines whether the servomotor is controlled in normal mode by comparing the parameter specified in it with the feedback signal received from the position sensor! while the safety device receives the set value and the feedback value from the servo drive, which is determined based on the feedback signal connection as a result of actuating the servomotor according to the set value, and generates a stop signal if one or both of the values including the set value and the value of fraternity, are abnormal values, and! the servo stops generating torque by the servo motor in response to receiving a stop signal from the safety device. ! 2. The servo system according to claim 1, in which the safety device generates a stop signal if a predefined condition is fulfilled that determines that one or both of the values including the set value and the feedback value are abnormal values, and! predefined condition �
