System Sampling Times And Number Of Controllable Drives - Siemens Sinamics S120 Function Manual

Resumption of DRIVE-CLiQ communication when autonomous mode is active
A distinction must be made between the two operating states below:
● The DRIVE-CLiQ bus timing, e.g. clock cycle settings, has not changed since the
● The DRIVE-CLiQ timing has changed:
The component may already be running when the second download takes place. To permit a
second download (reparameterization, factory setting, ...), the DRIVE-CLiQ master must
"deactivate" the protective function (if one is selected) and thus also autonomous time-slice
operation. All timing changes can be accepted in this state.
The DRIVE-CLiQ master performs a relevance check on the download (relevant here means
only those settings which affect the time-slice behavior of the component).
Reconfigurations which must be linked to the DRIVE-CLiQ slave with message "Timing
change" are
● Changes to the DRIVE-CLiQ clock cycle for the component
● Changes to oversampling settings which require internal reconfiguration of the time-slice
Please also note the following:
● Changes to component connections and longer cables between components require

System sampling times and number of controllable drives

The software functions installed in the system are executed cyclically with different sampling
times (p0115, p0799, p4099).
The sampling times of the functions are automatically pre-assigned when configuring the
drive unit.
These settings are based on the selected mode (vector/servo), the number of connected
components, and the functions activated.
The sampling times can be adjusted using parameter p0112 (sampling times, pre-setting
p0115), p0113 (pulse frequency, minimum selection) or directly using p0115.

The DRIVE-CLiQ component boots in cyclic mode.
Autonomous operation must continue at all costs. The DRIVE-CLiQ component refuses
to boot until the application signals that autonomous operation is no longer required. The
component can then restart with the modified clock cycle settings.
