Synchronism operating mode (overview)

Sampling time for real master and virtual master axis:
U953.31 = ___(20)
Recommended: U953.31/ 34=4 (use
same time slot as for synchronism!) The
real and virtual master axes are dedicated
autonomous free blocks.
Sampling time for synchronism [sheet 834...843]:
Real master value
U953.33 = ___(20)

U953.33 = 20 ==> Synchronism as

operates as an autonomous free
block (recommended: U953.33=4)
Only permitted if positioning modes
are deactivated (i.e. if U953.32=20)
U953.33<4 is illegal!
