52. RDC

52.1. Overview

The rdc example project demo position information from a rotary encoder.

52.2. Board Setting

Connect the rotary encoder driver board to the motor interface (Please refer to RDC Pin Description), then connect the rotary encoder to the driver board.

  • Driver board 14V power supply

  • RDC model SG52-4-G12.7

  • RDC encoder have 4 pole, so one turn of the electrical angle corresponds to 1/4 turns of the actual position.

52.3. Running the example

Rotate the motor and the serial terminal will output the angle information as follows:

 theta: 1.
 theta: 20.5.
