Measuring Function - Siemens Sinamics S110 Function Manual

Diagnostics
5.2 Diagnostics via STARTER
The unit cycle time display flashes 3 times at around 1 Hz when the time slice is changed
from < 4 ms to ≥ 4 ms (see description under "Properties").
Note
Please see the online help for more information about parameterizing and operation.
Properties
● Up to 4 recording channels per trace.
● Device cycle for individual trace: 0.25 ms
● Two independent trace recorders per Control Unit
● Trigger:
● STARTER parameterization and commissioning tool
● Settable trace cycle: Integer multiples of the basic sampling time

Measuring function

Description
The measuring function is used for optimizing the drive controller. By parameterizing the
measuring function, the impact of superimposed control loops can be suppressed selectively
and the dynamic response of the individual drives analyzed. The ramp-function generator
and trace function are linked for this purpose. The control loop is supplied with the ramp-
function generator signal at a given point (e.g. speed setpoint) and recorded by the trace
function at another (e.g. speed actual value). The trace function is parameterized
automatically when the measuring function is parameterized. Specific predefined operating
modes for the trace function are used for this purpose.

– Endless trace:
Activate Ring buffer to define the recording length more precisely. If the ring buffer is
deactivated, the trace records until the available memory space is filled.
– Device cycle for endless trace: 2 ms
– Without triggering (recording immediately after start)
– Triggering on signal with edge or on level
– Trigger delay and pretrigger possible
– Automatic or adjustable scaling of display axes
– Signal measurement via cursor
– Averaging of trace values:
If a float value is recorded with a cycle which is slower than the device cycle, the
values recorded will not be averaged.
