Incremental encoders Pulse encoders and SSI absolute encoders This application example describes the interface connection of encoder signals to SIMOTION technology objects using the technology modules TM Count 1x24V and TM PosInput 1. Incremental rotary encoder outputs the pulse corresponding to the rotation angle only while rotating, and is the counting measurement method that adds up the pulse from the measurement beginning point. An incremental encoder can measure the change in position but not the absolute position. Use incremental encoders with our PLC high-speed input modules for accurate position monitoring. Absolute encoders: Absolute encoder on the other hand indicates both the position and location of that position relative to the shaft rotation. Each code pattern forms a unique reference, and is therefore an absolute position. Their work is based on the three-channel type of outgoing signals. A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to analog or digital output signals. Measures the absolute rotary position even after power loss, for precise position measurement. This consists of a rotating disk, a light source, and a photo detector (light sensor). Absolute and incremental encoders both do this, but operate differently and have different methods of implementation.
