Absolute vs. incremental encoders: when are they appropriate?

June 11, 2025
The differences between incremental and absolute motor encoders and their impact on motion control systems

In the world of motor encoders, there are two main types – incremental and absolute. Incremental encoders do not retain their actual position upon power-up, whereas absolute encoders do. They both give position feedback, which the motion controller can use to calculate velocity, acceleration and jerk. These parameters are necessary for a fully capable motion control system.

In this episode of Control Intelligence, written by Joey Stubbs, editor in chief Mike Bacidore discusses absolute encoders.
