Resources
As resources, the cycle uses a block-wide synchronized action and a synchronized action
variable. The synchronized action is determined dynamically from the free area of the
synchronized action range (CUS.DIR - 1 ..., CMA.DIR - 1000 ..., CST.DIR – 1199 ...).
SYG_IS[1] is used as the synchronized action variable.
Examples
Example 1: Oscillation with two strokes:
Cycle parameters

● Stroke: 100 mm
● Sparking-out time: 1 s
● Infeed feedrate: 1 mm/min
● Transverse feedrate: 1000 mm/min
● Repetitions: 2
