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
actual position value is measured.
● 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.

TO measuringInput setting: Single
measurement
(Measurement jobs must be issued indi‐
vidually for each measurement. Several
interpolation cycle clocks lie between
two measurements.)

D410, D410-2, D4x5, D4x5‑2 (terminal
X122/X132), CX32, CX32‑2, CU310,
CU310-2, CU320, CU320‑2
With a signal edge at the relevant input,
the current actual values of an encoder
connected to a Control Unit are meas‐
ured with positioning accuracy to deter‐
mine lengths and distances.
The assignment of inputs is always per‐
manent depending on the hardware of
the Control Unit and is performed during
the configuration of the TO measuringIn‐
put using the measuring input number.

MP timer DIDQ
With a signal edge at the relevant input,
the current actual values of one or more
encoders are measured using time
stamp functionality with positioning ac‐
curacy in order to provide information for
determining lengths and distances (pos‐
sible with any encoders included in the
project).
The assignment of inputs is not fixed de‐
pending on the hardware and is per‐
formed during the configuration of the
TO measuringInput by means of sym‐
bolic assignment or the hardware ad‐
dress.
