MeasureofDancer constant:
SetthekeypadofthedriveontheparameterPID feed-back.
Measureandmultiplyby2,thedistancebetweenthelowermechanicalfullrangeandthepositionofthedancer
sothatintheparameterPID feed-back willdisplay0(positionof0electric).
Asthedancerhasonlyonepitch,multiplytheabovecalculatedvalueby2.
Inthiscaseset:
Dancer constant =640mm
ProgrammMinimum diameter equaltotheminimumvalueofthecorediameter[cm]:
Minimum diameter =10cm
