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
● 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.
Local measuring input
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
measured with positioning accuracy to
determine lengths and distances.
The assignment of inputs is always
permanent depending on the hardware
of the Control Unit and is performed
during the configuration of the TO
measuringInput using the measuring
input number.
Yes
Global measuring input
TM15, TM17 High Feature, D410,
D410-2, D4x5, D4x5-2 (terminal X122,
X132, X142), CX32, CX32-2, CU310,
CU310-2, CU320, CU320-2
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
accuracy in order to provide information
for determining lengths and distances
(possible with any encoders included in
the project).
The assignment of inputs is not fixed
depending on the hardware and is
performed during the configuration of
the TO measuringInput by means of
symbolic assignment or the hardware
address.
Yes
