Abstract: The present invention discloses a servo control system and a servo. A servo control system includes a main control module; and a communication module including a first communication interface, a second communication interface and a control switch unit. First communication terminal and second communication terminal of the control switch unit are correspondingly coupled to the first communication interface and the second communication interface. First enabling port and second enabling port of the control switch unit are correspondingly coupled to two enabling terminals of the main control module. The main control module receives, via the first enabling port, the first communication terminal and the first communication interface, an identification number or an identification number together with action instruction information from a servo of upper level, and transmits, via the second enabling port, the second communication terminal and the second communication interface, an identification number or an identification number together with action instruction information of a servo of lower level. In the above manner, the present invention can assign an identification number to a servo during initialization of the servo, avoiding the installing inconvenience caused by that servo identification numbers are fixed.

Abstract: A device sod a method for measuring servo gear idle position are provided. The method includes: outputting a start-up fixed force of a first rotation direction to an output shall of a servo under test, and recording a value of a start-up position of the output shaft when a position of a rotor of the servo under test changes for the first time; outputting a counterrotation force of a second rotation direction for rotating the output shaft to the output shaft, and recording a value of an counterrotation position of the output shaft when the rotor is in a stop status after a predetermined interval; and calculating a value of a servo gear idle position in a current measuring point, the value of the idle position is the absolute value of the difference between the value of the start-up position and the value of the counterrotation position.
