Synchro error blocking

For special cases (for example, external disturbances), it is possible to block speed
correction signal 03.35 SPEED CORR BUFF with parameter 97.19 SYNC ERR BLK
LVL. If the change in 02.23 SYNC POS ERROR is bigger than the value of 97.19
SYNC ERR BLK LVL, signal 03.35 SPEED CORR BUFF is blocked and no
synchronisation correction is performed during that period (in the following example
figure 20 ms).
78.09 SYNC ERR LIM (mm)
Change of 02.23 SYNC POS ERROR > 97.19 SYNC ERR BLK LVL (mm)
