SYNCMMHIT / SYNCSMHIT
SYNCMMHIT and SYNCSMHIT are set, when the
master marker resp. the slave marker is occurred.
These flags are deleted for every SYNCM com-
mand. Subsequently the flag SYNCMMHIT is set
after the first occurrence of a master marker pulse
or after the n-th marker pulse (parameters
SYNCMARKM 52).
The same is true for SYNCSMHIT with the slave.
NB!
This flag is no longer deleted unless SYNCM
is started again or explicitly deleted with
SYNCSTATCLR.
SYNCMMERR / SYNCSMERR
If in the marker window marker window marker window SYNCMWINM (68) or marker window
marker window
SYNCMWINS (89) a tolerance range is defined,
then SYNCMMERR or SYNCSMERR are set as
soon as the maximum distance allowed has been
achieved and no marker was identified.
Example:
Distance between two master markers
SYNCPULSM (58) = 30000
Marker Window SYNCMWINM (68) = 1000
The flag is set at 31000 if no marker is
identified.
These flags are deleted for every SYNCM
command.
If the marker window marker window is 0 and thus no tolerance marker window marker window marker window
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 parameter
SYNCPULSM (58). If not the corresponding flag is
set.
The same applies analogously for SYNCSMERR in
the slave.
NB!
This flag is no longer deleted unless SYNCM
is started again or deleted with
SYNCSTATCLR.

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.

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
NB!
ERRCLR contains the command MOTOR
ON, which automatically switches the con-
troller on again. (The motor is position-controlled at
the current position.)
