Caution
If you change the cycle times, check the behavior of the controller in all operating modes
before you finish commissioning.
Note
The smaller the cycle times (PROFIBUS DP cycle) chosen, the greater the control quality for
the drive and the better the surface quality on the workpiece.

Commissioning Manual, 11/2006, 6FC5397-2AP10-2BA0
Name / remarks
System clock cycle/only display data; is always
equal to the equidistant PROFIBUS DP cycle.
Note: For SINUMERIK solution line for display
only!
Factor for the position control cycle/is set fixed to
the factor 1.
Position Controller cycle
Position control cycle offset
[0] = DP cycle time
[1] = Position controller cycle offset
[2] = Position controller cycle offset + max.
computation time needed by the position controller
Factor for the interpolator cycle/can be freely
selected in integer multiples.
Computation time ratio NCK
