Table 10-8 Cycle times: Machine data
Number Identifier Name / remarks Reference
General ($MN_ ... )
10050 SYSCLOCK_CYCLE_TIME System clock cycle/only display data; is always
equal to the equidistant PROFIBUS DP cycle.
Note: For SINUMERIK solution line for display
only!
10060 POSCTRL_SYSCLOCK_TIME_RATIO Factor for the position control cycle/is set fixed to
the factor 1.
10061 POSCTRL_CYCLE__TIME Position Controller cycle
10062 POSCTRL_CYCLE_DELAY Position control cycle offset
10063 POSCTRL_CYCLE_DIAGNOSIS [0] = DP cycle time
[1] = Position controller cycle offset
[2] = Position controller cycle offset + max.
computation time needed by the position controller
10070 IPO_SYSCLOCK_TIME_RATIO Factor for the interpolator cycle/can be freely
selected in integer multiples.
10185 NCK_PCOS_TIME_RATIO Computation time ratio NCK
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.
