CAM Master Start
Function
SYNCMSTART defines whether at start the synchro-
nization should be made to the leading, subsequent
or closest marker impulse of the master.
SYNCMSTART is only valid for synchronization with
marker correction (SYNCM and SYNCCMM).
0 = The slave marker following the first master
marker (after SYNCM) is aligned with the first
master marker.
1 = The first slave marker (after SYNCM) is aligned
with the following master marker.
2 = After reaching the master velocity the next
2 markers will be aligned (correction can be
forward or backward).
3 = After reaching the master velocity the next
slave marker will be aligned with the master
marker in front (correction is forward).
4 = After reaching the master velocity the next
slave marker will be aligned with the marker
behind (correction is backward).
5 = After reaching the master velocity the next
slave marker will be aligned with the closest
master marker (correction can be forward or
backward, always the shortest distance).
6 = After the command SYNCM the first two mar-
kers are taken and the program synchronizes
to these markers.

7 = Start with a polynomial 5
exactly in a marker position.
1000 = as [0], but an offset (par. 33-12
SYNCPOSOFFS) is not active before the first
marker correction is done.
1001 = as [1], but an offset is not active before
the first marker correction is done.
1002 = as [2], an offset is not active before the
first marker correction is done.
1003 = as [3], an offset is not active before the
first marker correction is done.
1004 = as [4], an offset is not active before the
first marker correction is done.
1005 = as [5], an offset is not active before the
first marker correction is done.
1006 = as [6], an offset is not active before the
first marker correction is done.
1007 = as [7], an offset is not active before the
first marker correction is done.
2000 = Counting of the master pulses in MU begins
with the master marker.
NB!:
Only the parameter 2000 is effective in
curve synchronizations.
Parameter 7 and 1007 are supported starting with
MCO 5.00. How the parameters operates is
specified in the online help.
33-24 Marker Number for Fault
SYNCFAULT
Range
0 – 10000
Function
Defines how often during a marker synchronization
(SYNCM and SYNCCMM) an inaccuracy may occur
during a synchronization evaluation before a FAULT
is registered.
In the program this condition can be queried using
SYNCSTAT.
