A.3
Configuring local measuring inputs
Properties
Local measuring inputs are always permanently assigned to an axis (drive). They are
configured separately for each drive. The drive and the measuring input input must always be
located on the same control unit. The measurement results are transferred using the axis
message frame in accordance with the PROFIdrive profile. Message frame 39x does not need
to be configured for local measuring inputs.
The settings for the use of the local measuring inputs must be made in the expert list.
Procedure
In order to use an I/O terminal on a D4x5‑2, CX32‑2 or SINAMICS control unit as measuring
input input, proceed as follows:
1. Double-click the "Inputs/outputs" entry below the control unit in the project navigator.
2. Click the "Bidirectional digital I/Os" tab.
3. In this tab, configure the required I/O terminal as input. The configuration can also be set
channel-granular on the p0728 parameter using the expert list of the control unit.
Specification of the measuring input input terminal must be made in the expert list of the
respective drive for local measuring inputs.

As a maximum of three encoders can be assigned to a drive, the index [0..2] specifies whether
the measurement applies to encoder 1, 2, or 3.
The following must be taken into account:
● Only two TO measuringInputs can be configured per TO axis or TO externalEncoder
● Only one TO measuringInput can be active on a TO axis or TO externalEncoder.
