Abstract
A servo motor controller for controlling a machine includes a first receiver circuit for receiving signals from an encoder that detects the position of the machine and a second receiver circuit for receiving signals sent from a sensor unit. The first receiver circuit has the same configuration as the second receiver circuit, and the same interface is used between the sensor unit and the second receiver circuit as is used between the encoder and the first receiver circuit.
Claims6
A machine controller comprising:
- a servo motor;
- a sensor unit having a sensor for detecting a state of a machine driven by the servo motor and means for transmitting information detected by the sensor to the outside;
- a receiver circuit for receiving signals sent from an encoder which detects the position of said machine;
- and
- a servo motor controller for receiving the information detected by said sensor and driving said servo motor according to the received information;
- wherein the communication protocol of said sensor unit is made identical to that of the encoder, and
- the receiver circuit for receiving signals sent from the encoder is used as a receiver circuit for receiving signals sent from said sensor unit.
