4.3 Encoders
Incremental encoder with zero track
The incremental encoder is located under the fan cover and is attached to this. After installation, the
zero point offset is measured in the final test. The offset is provided with an adhesive label in the
terminal box.
Absolute encoders
The synchronisation of the encoder is adjusted by NORD prior to delivery of the geared motor and
does not require determination of the offset.
If the encoder is not synchronised, or has come out of adjustment due to an impact or removal of the
motor, the zero track of the encoder must be synchronised to the rotor position.
