Whatever applications you intend to use our drives for, whatever electronics the speed feedback from the drives is to be linked up to, xxx from our diverse range of encoders.
Do you need speed, torque or positioning control? We can implement your requirements with our incremental and absolute encoders.
Would you like to reduce the outlay associated with connections? Single-cable technologies such as MOVILINK® DDI are the solution you need.
The electronic nameplates integrated into the sine and absolute encoders enable simple startup.
Encoders with MOVILINK® DDI interfaces automatically take care of the data exchange in seconds and reduce the startup procedure to system-specific adjustments and optimizations.
The optimum interaction of the individual system components is particularly important in applications with control tasks. Motors in particular must respond to commands from the drive electronics with precision. We can supply you with the necessary encoder systems.
They ensure the system can identify a position or a change in position and feed this back to the drive electronics. With absolute encoders, you save valuable time during plant initialization.
Our large selection of encoders enables you to control your drive and therefore your plant according to your requirements:
Ability classes are used to identify the functionality of the encoder system, irrespective of the drive system involved. These classes are the Basic Class, Medium Class, and High Class. This makes it possible to find the perfect solution to fit your drive task.

Add-on encoders are encoder systems that SEW-EURODRIVE purchases from renowned manufacturers. They meet our requirements in terms of performance, precision and standardization in full.
They are available for all series of asynchronous motors, synchronous motors and linear motors.
Add-on encoders are always used when various electrical interfaces in our modular system are to be available on an overarching basis and when special features such as explosion protection and functional safety must be ensured.
Just like our built-in encoders, add-on encoders can be flexibly combined with our frequency inverters and controllers. As a result, the SEW-EURODRIVE modular system provides a quick solution for your requirements.
The built-in encoders for DR.. series asynchronous motors are unique. They are available in Basic Class and Medium Class and are perfectly integrated into the motor. This means that encoder mounting does not add additional length to the motor.
For example, if you use a MOVITRAC® advanced standard inverter, you can successfully implement applications that would have previously required rapid/creep speed switching with initiator evaluation.
Built-in encoders are very beneficial when used in our synchronous motors from the CMP.. and CM3C.. series, too. When combined with our single-cable-capable MOVILINK® DDI interface and the MOVI-C® modular automation system, it is possible to both integrate the encoder perfectly into the motors and digitalize the drive. For example, it only takes seconds for the drive on the inverter to start up automatically. Alongside the encoder, the condition monitoring functions of the drive are also digitalized.
