G3: Cycle times

3.1

Brief description

This description explains the relationships and machine data of the various system cycles of
the NC:
• Basic system clock cycle
• Interpolator cycle
• Position controller cycle
SINUMERIK 840D
For SINUMERIK 840D the position control cycle and the interpolator cycle (IPO cycle) are
derived from the system clock cycle, which is set in the machine data of the NC.
SINUMERIK 840Di
In SINUMERIK 840Di the position control cycle and the interpolator cycle are derived from the
system clock cycle, which is synchronized with the equidistant DP cycle T
creating the configuration in the S7 project (⇒ No setting of system clock cycle in SINUMERIK
840Di via machine data of NC).
