62 SYNCMSTART
SYNCMSTART defines whether at start the syn-
chronization should be made to the leading, sub-
sequent or closest marker impulse of the master.
SYNCMSTART is only valid for synchronization with
marker correction (SYNCM and SYNCCMM).
Content
Start behavior for synchronization with marker
correction
Parameter Group
Axis parameter Synchronization AXS
CAM-Editor: index card Synchron.
Value range
0 ... 6 and 1000 ... 1006, 2000
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
markers are taken and the program
synchronizes to these markers.
1000 ... 1006 = as above, an offset
(SYNCPOSOFFS) is not active before the first
marker correction ist done.
2000 = in CAM mode: Counting of the master
pulses in MU begins with the master marker.
NB!
Only the parameter 2000 is effective in curve
synchronizations.

63 REVERS
REVERS determines the behavior while moving in
reverse (moving in a negative direction): whether
reverse is allowed, only allowed when the master is
reversed or not allowed in general. . . . .
REVERSE is always valid even for the positioning
errors VEL and "TESTRUN".
In order to prevent automatic reversing during the
"TESTRUN" adjust the value to 1 or 2.
