Details: AVS78E

Function

This absolute rotary encoder returns a position value corresponding to the shaft position via the SSI interface.

In order to obtain the position data, the controller sends a start sequence to the absolute rotary encoder. The encoder then responds synchronously to the pulses from the controller with the position data.

The modular design enables you to order the absolute rotary encoder so that it fulfills your requirements. A listing of the part options can be found in the ordering information.

You can select the counting direction via 2 functional inputs and set the zero position.
