System Sampling Times - Siemens Sinamics S110 Function Manual

Basic information about the drive system

10.6 System sampling times

10.6 System sampling times
The software functions installed in the system are executed cyclically at different sampling
times.
The sampling times of the functions are pre-assigned automatically when the drive unit is
configured.
● Current controller 250 μs
● Speed controller 250 μs
● Flux controller 250 μs
● Setpoint channel 4,000 μs
● Position controller 1,000 μs
● Positioning 4,000 μs
● Technology controller 4,000 μs
For p0092 = 1, the sampling times are pre-assigned so that isochronous operation together
with a control is possible. If isochronous operation is not possible due to incorrect sampling
time settings, then an appropriate message is output (A01223, A01224). Before the
automatic configuration, parameter p0092 must be set to "1" in order that the sampling times
are appropriately pre-set.
● p0009 Device commissioning, parameter filter
● p0092 Isochronous PROFIBUS operation, pre-assignment/check
● p0097 Selects the drive object type
● p1800 Pulse frequency
● r9780 SI monitoring clock cycle (Control Unit)
● r9880 SI monitoring clock cycle (Motor Module)
