Parameter U601 [834.2] must be set to zero for linear axes, i.e. for
drives with an infinite traversing range.
In the case of rotary axes, the cycle length matches the product length
(e.g. packaging machines).
When there is no fixed product length, e.g. on continuous rollers, the
axis cycle can be freely defined, in which case it is normally set to
match the positional difference corresponding to one motor or roller
movement.
When the virtual master axis is used, its cycle length must be specified.

Master axis cycle U601
Slave axis cycle U501.11 (MD11)
The above description for the master axis cycle applies analogously to
the slave axis cycle [836.6]. The axis cycles for the master and slave
can be set to different values.
Synchronization mode U602 U656
Synchronization mode [834.5] defines whether the synchronization
block operates in
♦
Continuous cycle
Value = 0
♦
Engaging cycle
Value = 1
♦
Disengaging cycle
Value = 2
♦
Uncoupler
Value = 3
The cycle can be set by parameter or binector. Parameter U656 defines
the binectors for the switchover.
If the catch-up is used here, it is imperative to parameterize the scaling
rate master (U607.2). If the catch-up is selected as operating mode, the
catch-up on FP 836.2 is inactive. It can only be used once (either FD
834 or FD 836).
