Commissioning Manual, 05/2008, 6FC5397–4CP10–4BA0
The maximum value for the NC CPU time share of 75 % must not be exceeded. A value
greater than 75 % can lead to significant impairment (slowing down) of Windows XP
applications. If necessary, the values must be adapted to the system clock cycle/position
controller cycle (DP cycle time) and/or interpolation cycle.

10050
SYSCLOCK_CYCLE_TIME
System clock cycle/only display data; is always equal
to the equidistant PROFIBUS DP cycle.
Note: In 840Di sl only for display!
10060
POSCTRL_SYSCLOCK_TIME_
RATIO
Factor for the position control cycle/is set fixed to the
factor 1.
Note: Is not displayed for 840Di sl!
10062
POSCTRL_CYCLE_DELAY
Position control cycle offset
10070
IPO_SYSCLOCK_TIME_RATIO Factor for the interpolator cycle/can be freely selected
in integer multiples.
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.
