Uniparts Group Diploma Electrical Engineer Interview Questions and Answers

Incremental encoder measures relative position changes while absolute encoder measures absolute position.

• Incremental encoder generates a series of pulses as the shaft rotates, which are used to determine the relative position change.

• Absolute encoder generates a unique digital code for each shaft position, providing absolute position information.

• Incremental encoder is simpler and less expensive, while absolute encoder i...read more
