Example:
Distance between two master markers par. 33-17 = 30000
Master Marker Tolerance Window par. 33-21 SYNCMWINM = 1000
The flag is set at 31000 if no marker is identified.
These flags are deleted for every SYNCM command.
If the Master Marker Tolerance Window is 0 and thus no tolerance range is defined,
the program checks every marker pulse (or after every n-th pulse) whether the
distance between the two last markers registered is less than 1.8 times the value
defined by the par. 33-17
Master Marker Distance . If not the corresponding flag is
set.
The same applies analogously for SYNCSMERR in the slave.
NB!:
These flags are automatically reset: during the next successful marker correction
and in the event of a new start of SYNCM or through the command SYNCSTATCLR.

Syntax Example IF (SYNCSTAT & 4) THEN OUT 1 1 /* If ACCURACY then set output */

SYNCSTATCLR
Summary Resetting of the flags MERR and MHIT
Syntax SYNCSTATCLR value
The SYNCSTATCLR command should only be used in a subprogram for dealing with
errors. (see ON ERROR GOSUB).
Parameter value = 8 = SYNCMMHIT
16 = SYNCSMHIT
32 = SYNCMMERR
64 = SYNCSMERR
Description The corresponding bits can be reset in SYNCSTAT with SYNCSTATCLR value thus
resetting the error flags MERR and the HIT flags MHIT. None of the other flags can
be altered.
Command Group SYN
Cross Index ON STATBIT, ON ERROR GOSUB, ERRNO, CONTINUE, MOTOR ON
Syntax Example SYNCSTATCLR 32 /* clear current error message */
