Abstract
The present invention provides a configuration which enables an improvement in the workability of wiring of a sensor in a servo system. An encoder detects the operation of a motor driven by a servo driver, and generates a feedback signal indicating the detected operation. Further, the encoder receives detected signals output from sensors for detecting an object driven by the motor via sensor cables. The encoder outputs the feedback signal and the input detected signals to the outside.
Claims22
An encoder comprising:
- a signal generator configured to detect an operation of a motor driven by a servo driver and generate a feedback signal indicating the detected operation;
- an input unit configured to receive, via a sensor cable, a detected signal output from a sensor which detects an object driven by the motor;
- and
- a communication unit configured to output to an outside the feedback signal generated by the signal generator and the detected signal input to the input unit.

A servo system comprising:
- first and second motors;
- first and second servo drivers configured to drive the first and second motors, respectively;
- first and second sensors allocated to the first and second motors, respectively, and configured to detect objects driven by the allocated motors and output detected signals;
- a first encoder configured to transmit to the first servo driver a feedback signal indicating an operation of the first motor, receive via a sensor cable the detected signal from the first sensor or the second sensor, and transmit the detected signal to the first servo driver;
- and a second encoder configured to transmit to the second servo driver a feedback signal indicating an operation of the second motor, receive via a sensor cable the detected signal from the first sensor or the second sensor, and transmit the detected signal to the second servo driver, wherein
- when each of the first and second servo drivers receives a detected signal from a sensor allocated to the servo driver via the corresponding encoder, the servo driver is configured to determine to process the detected signal, and when each of the first and second servo drivers receives a detected signal from a sensor allocated to a servo driver different from the servo driver via the corresponding encoder, the servo driver is configured to transfer the detected signal to the different servo driver.
