Diameter calc Enablingoftheinitialfunctionofdiametercalculation.
ThecalculationwillbeenabledbysettingDiameter calc =Enable.
IfDiameter calc hasbeenprogrammedonadigitalinput,thismustbebroughttoa
highlogiclevel.

phaseoftheinitialdiameter.
Max deviation ValueexpressedincountofD/Awhichcorrespondstothemaximumshiftallowedby
thedancer.Thisvaluewillbeassociatedwiththestartingmeasurementofthedancer
movementduringthecalculationoftheinitialdiameter.
Duringthepreliminaryphaseofthecommissioning,itisnecessarytocarryouttheself-calibrationoftheanalog
inputs,soatthefullrangepositionofthedancertheywillcorrespond,whateverwasthevalueoftheanaloginput,
at10000counts.TheparameterMax deviation,inordertoguaranteeaprecisecalculationofthemovement,
mustbesetatavalueslightlylower.(standardMax deviation =8000).

MeasurementofDancer constant:
Withdancerinlowerfullrangeposition,performtheself-calibrationoftheanaloginputprogrammedasPID
feed-back.
SetthekeypadofthedriveontheparameterPID feed-back.
Measureandmultiplyby2,thedistanceinmmbetweenthelowermechanicalfullrangeandthepositionofthe
dancerthat,ontheparameterPID feed-back, willdisplay0(positionofelectrical0).
Multiplytheabovecalculatedvalueby2ifthedancerhasonlyonepitch,by4ifthedancerhastwopitchesand
