<1> The position setpoint master axis must be wired up. Optionally,
the speed setpoint can also be used to increase the accuracy
of the speed precontrol. The position setpoint and speed
source must match.
Example: Virtual Master
U600.3 = KK0817 [LU]
U600.6 = KK0820 [%]
Example: Real Master
U600.2 = KK0608 [LU]
U600.5 = KK0624 [%]
<2> Here give preference to wiring of source module "Additive
Offset" [794]
U460.1 = KK0835 [LU]
U460.2 = KK0832 [%]
KK7031 = Double word 1 of SIMOLINK [150]
KK0817 = Position of virtual master axis [820]
KK0816 = Speed of virtual master axis [820]
KK0608 = Position of real master [833]
KK0624 = Speed of real master [833]
If catch-up mode is selected,
the catch-up on FD 836.2 is inactive.

U888 specifies the direction of the position difference of the master
value during synchronization.
1.) Sign of the position difference of the master value is
being processed
(U888.01 input value = 0) AND (U888.02 input value = 0)
(U888.01 input value = 1) AND (U888.02 input value = 1)
2.) Positive position differences of the master value expected
(U888.01 input value = 1) AND (U888.02 input value = 0)
3.) Negative position differences of the master value expected
(U888.01 input value = 0) AND (U888.02 input value = 1)
