5.1.7.2 NC - Configuration
Appending and parameterizing an NC task
After appending an NC task the cycle time of the block execution task (NC task x SAF) has to be
parameterized. The cycle ticks define the cycle time in multiples of the set basic TwinCAT time (standard:
1 ms) for the task. The cycle time takes effect if/when auto start is selected. The task cycle time must be
greater than the expected fieldbus cycle time (Estimated DP Cycle Time - see section I/O Configuration
[} 101]). Shorter times than 2 ms have not yet been tested with Sinamics S120.
