Abstract

The embodiment of the invention provides an encoder calibration system and a control method thereof, and relates to the field of encoder calibration. The invention aims to solve the problem that the precision of an existing encoder calibration system needs to be improved. According to the encoder calibration system, a motor is provided with an output shaft, an encoder to be calibrated and a standard encoder are both connected with the output shaft, the encoder to be calibrated is used for outputting a first rotating speed signal, the standard encoder is used for outputting a second rotating speed signal, and a controller is used for carrying out first-time precision compensation on the encoder to be calibrated according to the first rotating speed signal and the second rotating speed signal. The control method of the encoder calibration system is executed by the controller. The rotating speed can reflect the running state of the motor more directly, the encoder to be calibrated and thestandard encoder both output rotating speed signals, precision compensation is carried out through the rotating speed, the compensation precision is higher, meanwhile, the encoder to be calibrated and the standard encoder are connected through a shaft, the running variables of the motor are the same, and the calibration precision of the encoder to be calibrated is improved.

Description

technical field [0001] The present invention relates to the field of encoder calibration, in particular to an encoder calibration system and its control method. Background technique [0002] Servo motors have undoubtedly become the core actuators of automation equipment. As the price of servo systems decreases year by year, many servo motor manufacturers are under pressure in terms of cost control. Especially for low-inertia and low-power servo motors that are in high demand, if a battery-type optical absolute encoder is used, the cost of the encoder can even reach 1 / 2 of the cost of the motor. [0003] In order to solve the cost pressure, more and more servo manufacturers have begun to try to use the magnetic principle to create their own magnetic encoders (hereinafter referred to as magnetic encoders). Magnetic braiding has the characteristics of strong shock and vibration resistance, corrosion resistance and oil pollution. In addition, due to the simple structure, the ...
