56 SYNCREADY
SYNCREADY defines how often during a marker
synchronization (SYNCM) a synchronization evalua-
tion with ACCURACY must be completed with
accuracy so that ready is fulfilled.
ACCURACY is checked during every correction. If
ACCURACY is fulfilled then 1 is added until the
set marker number has been achieved.
Synchronization evaluation is always executed after
n marker pulses by the master SYNCMARKM (52).
ACCURACY and READY can be queried using
SYNCSTAT.

57 SYNCFAULT
Defines how often during a marker synchronization
(SYNCM) an inaccuracy may occur during a syn-
chronization evaluation before a FAULT is regis-
tered.
In the program this condition can be queried using
SYNCSTAT.

58 SYNCMPULSM
SYNCMPULSM indicates how many qc (master) lie
between two master markers.
If you use the encoder index impulse as a marker
signal, then the distance between two markers is
the resolution (qc) of the encoder.
If external marker signals are used, then it is pos-
sible to measure the marker distance with the
program "marker count" (refer to program sample
in Chapter 7), if it is unknown.
SYNCMPULSM is only valid for marker synchroni-
zations (SYNCM).
