Document Type and Number:
WIPO Patent Application WO/2019/155700
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a servo system which can handle various kinds of sensors having different specifications. The present invention is provided with: an encoder which detects a rotation of a motor; a sensor which detects a state different from the rotation; and a sensor hub which is connected to each servo amplifier that drives and controls the motor, wherein the sensor hub is detachably connected with the encoder. The sensor hub performs signal processings on an encoder signal output from an encoder and a sensor signal output from the sensors, and transmits the processed signals to the servo amplifier.
