54 SYNCPOSOFFS
Defines the offset for position synchronization
(SYNCM, SYNCP). The offset is also valid for posi-
tion synchronization with marker correction.
This position offset can be altered online at any time
during the synchronization with a command.
NB!
The offset will be executed immediately when
the command SYNCP follows.
NEW
When SYNCM is started, however, the system waits
for the first evaluation of the market pulses. Only
then is the offset applied.
Compatability
To avoid compatibility problems you should
determine the start-up behavior of SYNCM with
SYNCMSTART.

55 SYNCACCU RACY
Defines how large the difference between the
actual master and slave position can be during a
position synchronization (SYNCP and SYNCM), so
that the required accuracy is still fulfilled. In con-
trast SYNCERR provides the actual synchronization
error of the slave in user units.
In the program you can query whether
SYNCACCURACY will be fulfilled using SYNCSTAT.
SYNCACCURACY is important for the marker syn-
chronization in order to be able to report READY,
since otherwise SYNCERR would have to be
queried and compared beforehand.

0 … MLONG A plus sign supplies the absolute
value to SYNCERR.
–MLONG … –1 A minus sign supplies the syn-
chronization error to SYNCERR
with polarity sign. It is then pos-
sible to tell whether the
synchronization is running ahead
or behind.
