Double
reference run
802
During the double reference run, the absolute position is first output through
the EnDat interface of the speed encoder. If at a later time the reference mark
of the position encoder is traversed, the control continues to work with this
reference.
Set the corresponding bits in MP1355 to 1 for the axes for which the double
reference run is to be used.
The distance between the speed encoder and the position encoder must be
entered in MP1356.x. When the reference mark of the position encoder is
first traversed, the message Set MP1356.<axis number> to <value> appears.
Enter this value in MP1356.x.
Define the behavior of W1032/W1116 in MP1357.x.
