SIMOVERT MASTERDRIVES Motion Control
The search for reference direction must be compatible with the parameterization of the 2nd
digit of P183.i001 in the Motion Control. If negative direction ... is selected in the window
(diagram above), P183.i001=xx2x must be entered in the Motion Control. If positive direction
... is selected, then P183.i001 = xx1x must be set in the 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.)
