A.2 Local and global measuring inputs
Local and global measuring inputs
Depending
on the used hardware platform, the following local and global measuring inputs are
available for the measuring tasks:
● Local measuring inputs are axis-related and implemented in the SINAMICS drive. The
measurement records the actual position value.
● Global measuring inputs can be freely assigned to the axes and add an internal time stamp
to the measurement result for more precise determination of the axis positions.
The term "central measuring input" is also used within the context of drives.

Measurement procedure With a signal edge at the relevant input, the
current actual values of an encoder con‐
nected
to a control unit are measured with
positioning accuracy to determine lengths
and distances.
With a signal edge at the relevant input, the
current actual values of one or more encod‐
ers are measured using time stamp function‐
ality with positioning accuracy in order to
provide information for determining lengths
and distances (possible with any encoders
included in the project).
Configuration of the TO measur‐
ingInput in SIMOTION SCOUT
The assignment of inputs is always perma‐
nent depending on the hardware of the
control unit and is performed during the
configuration
of the TO measuringInput us‐
ing the measuring input number.
The assignment of inputs is not fixed de‐
pending on the hardware and is performed
during the configuration of the TO measur‐
ingInput by means of symbolic assignment
or the hardware address.
Measuring input TO setting:
Single measurement
1)
yes yes
Measuring input TO setting:

The minimum interval between 2 measure‐
ments
is 3 servo cycle clocks (max. 2 edges
per measurement).
D4x5‑2 (terminal X142), TM17 High Feature:
The minimum interval between 2 measure‐
ments is 1 servo cycle (max. 2 edges per
measurement).
TM15:
No cyclic measurement available
