"Quasi-absolute"

Initialization of a validate absolute position

The MQR3000F is a “quasi-absolute” encoder.

"Quasi-absolute" means that it is an incremental encoder that provides a valid absolute position only after initialization.

Therefore the belt lock must pass the sensor head twice in the same direction. The zero position will then be set to the middle of the belt lock and the encoder delivers valid absolute position data.
