Bonjour tout le monde,

Connaissez-vous l'équivalent français de "home reference point" ?

Voici un contexte similaire à celui dans lequel apparaît cette expression dans mon document.

Home Sequence
1. Back off the sensor.
2. Move to the external home sensor to establish a home reference point.
3. Next it will move to the Offset position.
4. Then the command and feedback positions are set to the value entered into the End of Home Position.
Homing to the motor’s encoder marker will establish the most accurate and repeatable home position. This method will position the motor relative to the location of the rising edge of the encoder marker pulse. Most applications will use a sensor and marker to find an accurate home position in the vicinity of the home sensor.

Merci d'avance de m'éclairer !
