andnegativelimitswitch
8.5.11.1Method(11)
 Reversalofdirectionofmovementafteractivereferencemark.Thezeropoint
correspondstothefirstzeropulseafterthefallingedge.
 Zeropointatthefirstzeropulseafterfallingedgefromthereferencemark.
 Movementmusthavegonebeyondthereferencemark,thenthefirstzero
pulsecorrespondstothezeropoint.

8.5.11.2Method(12)
 Zeropointcorrespondstothefirstzeropulseifthereferencemarkisactive.
 Reversalofdirectionofmovementafterafallingedgefromthereference
mark.Thezeropointcorrespondstothefirstzeropulseafterarisingedge
fromthereferencemark.
 Reversalofdirectionofmovementwhenthereferencemarkhasbeen
passed.Thezeropointcorrespondstothefirstzeropulseafterarisingedge.
