Figure 15-7 Synchronization with rising reference cam signal edge
Electronic reference cam offset
Electronic reference cam offset is used for compensating reference cam length increases caused by
temperature:
MD34092 $MA_ REFP_CAM_SHIFT (electronic reference cam offset for incremental measuring systems with
equidistant zero marks)
After a rising or falling reference cam edge is detected the axis is synchronized for the next encoder zero mark
only after the cyclically calculated offset path has been covered.
Because the offset path s
shift
is calculated by the NC in IPO cycles, the following minimum and maximum offset
paths s
shift_min
and s
shift_max
will result:
The reference cam offset acts in the direction of zero mark search.
Prerequisite
The reference cam offset is only active for machine axes for which a reference cam has been parameterized:
MD34000 $MA_REFP_CAM_IS_ACTIVE = 1
s
shift_min
=
MD34092 $MA_ REFP_CAM_SHIFT
s
shift_max
=
MD34092 $MA_ REFP_CAM
MD34040 $MA_REFP_VELO_SEARCH_MARKER * interpolation cycle
