Tech/Engineering - Electronics / Elect Eng | | French term or phrase: butées fonctionnelles | General context: positioning various control surfaces. Found in the description of a servomechanism mode:
Le mode "purge" pour un débattement automatique des gouvernes aux butées fonctionnelles des servocommandes.
Any help gratefully received.
Thanks. |

| | normal end-stops | Explanation:
Difficult to tell what these 'butées' are without seeing a drawing. But perhaps there are several sets of them, 'butées fonctionnelles' which define the normal operating range of the servo, and (for example) 'butées d'arrêt d'urgance' to prevent damage if the thing goes out of control.
'butées fonctionnelles' might also refer to a particular set of end-stops that are active, as distinct from other sets that are 'inactive' (depending on the required rangeof operation, for example).

--------------------------------------------------
The additional context given by Peter tells us something is turning between angular limits, and is consistent with the 'normal end-stops' idea.
The fact that the butées can be 'réduits de 5 degrés' suggests they might be software limits in the servo controller. As Bourth suggests, swinging the system between its normal limits could serve a purging function (maybe a hydraulic system, maybe something quite different like a machine workspace). Swinging the system between reduced limits would be a reasonable way to check/align the servo (if it swings 'twixt the reduced limits without hitting an end-stop, then it's aligned to within 5°, which is presumably good enough - if it does hit a stop, then the thing can be tweaked until it doesn't). |

| Notes to answerer
Asker: Unfortunately I don't have a diagram, but there is another mention of "butées fonctionnelles" that also refers to purge mode:
"L’outillage asservit la servocommande en balayant les valeurs des butées fonctionnelles réduites de 5 degrés." Elsewhere, there is also a mention of purging hydraulic circuits.
