SIMOVERT MASTERDRIVES Motion Control
The settings of the Technology-CPU must be compatible with the parameterization of the
2nd digit of P183.i001 in the Motion Control. This means: If, as Start search for reference is
selected in the window Negative direction and for Zero mark "Behind reference cam", then
P183.i001 must be xx2x in Motion Control and if Negative direction is selected and for
Encoder zero marks "In front of reference cam", then P183.i001=xx1x must be in Motion
Control. If, on the other hand as Start search for reference in the Positive direction is
selected in the window and for Encoder zero mark "behind reference cam" (the following two
diagrams), then P183.i001 must be xx1x in Motion Control, if Positive direction is selected
and for Encoder zero mark "In front of reference cam", then P183.i001 must be xx2x in
Motion Control.
(The parameterization of U922.i005 and U923.i001 in Motion Control must be left at its
standard values KK120 and B210 corresponding to the following description.)
The reference cam should be connected to the input integrated in the Technology-CPU or at
the distributed input at DP(DRIVE), that was configured in the window reference axis (the
following two diagrams). When this reference cam is reached, the referencing function is
enabled in the drive.
