Encoder and control system

A control system comprising:

• an encoder;
• and
• a control device processor configured to control a target object by using information transmitted from the encoder by serial communication, wherein
• the encoder is configured to:
• generate position information made of a predetermined amount of data and including absolute position data of an object to be detected and multi-rotation data of the object to be detected,
• generate configuration information representing a distribution of the absolute position data and the multi-rotation data in the predetermined amount of data during serial communication, and
• transmit, to the control device processor, the position information and the configuration information as serial data, and
• the control device processor is configured to:
• receive the position information and the configuration information transmitted from the encoder,
• process the position information received on the basis of the configuration information received, and
• store only the configuration information transmitted from the encoder,
• wherein the control device processor transmits, to the encoder, a request signal for the position information at a predetermined cycle,
• wherein, when the encoder receives the request signal from the control device processor, the encoder transmits the configuration information along with the position information to the control device processor as the serial data, the control device processor stores only the configuration information, the control device processor processes the position information received on the basis of the configuration information received;
• and
• wherein, when the encoder receives a subsequent request signal from the control device processor, the encoder transmits the position information as the serial data to the control device processor, the control device processor processes the position information received on the basis of the configuration information stored.
