Absolute encoder, incremental encoders and accessories

The built-on optoelectronic rotary encoders measure paths, angles of rotation or speeds in machines. They can be used in conjunction with computerized numerical controls, programmable logic controllers, drives and position displays, e.g. for:

• SINUMERIK CNC controls
• SIMOTION Motion Control Systems
• SIMATIC programmable logic controllers
• SINAMICS drive systems

A distinction is made between incremental and absolute measuring procedures:

• In the case of incremental encoders, the machine must travel to a reference point after each power‑off state, as the position is not usually stored in the controller, and movements of the machine while the power is off are not recorded.
• Absolute encoders, on the other hand, also record these movements while the power is off and return the actual position with power On. Travel to a reference point is not necessary.
