100931 Digital inputs preset reference
Description
The block generates the control signals from the binary inputs or from control word
D212
for
the comfort reference value application. The control signals are used to select a preset
reference value, a preset value, the acceleration ramp and the deceleration ramp. The
output of the control signals is updated based on a level or edge-triggered enable. The
source of the edge-triggered enable is set in
D128
edge enable PR/FR source (binary input
or
D212
bit 14). The source for level-triggered enabling is selected in parameter
D129
level
enable PR/FR source (binary input or
D212
bit 15).
Both enables can be parameterized with a switchon and switchoff delay (
D428
.x and
D429
.x).
The block updates the monitoring parameters
D328
and
D329
.
When the fieldbus is activated as the source in
D125
.0 (
2:Parameter
), bits 0 to 2 of control
word
D212
are used to select a preset reference value and bits 3 to 5 are used to select a
preset value. This means that only 8 preset reference values can be set per fieldbus when
preset values are selected by fieldbus. If the fieldbus is not activated as the source in
D125
.0, a selection of 16 preset reference value is available in bits 0 to 3 of
D212
.
NOTE
The block is used automatically in the configuration of the axis if you generate the comfort
reference value application.

PRRefSel
U8 –
The output supplies the state of the sources which were specified via
parameter
D124
.0
to
D124
.3 combined in one U8 value (binary inputs
or
D212
bit 0 to bit 3).
The comfort reference value application uses the value to select a
preset reference value.

PRValSel
U8 –
The output supplies the state of the sources which were specified via
parameter
D125
.0
to
D125
.2 combined in one U8 value (binary inputs
or
D212
bit 3 to bit 5).
The comfort reference value application uses the value to select a
preset reference value.
3
PRAccSel
U8 –
The output supplies the state of the sources which were specified via
parameter
D126
.0
to
D126
.3 combined in one U8 value (binary inputs
or
D212
bit 6 to bit 9).
The comfort reference value application uses the value to select a
preset reference value-acceleration ramp.
4
PRDecSel
U8 –
The output supplies the state of the sources which were specified via
parameter
D127
.0
to
D127
.3 combined in one U8 value (binary inputs
or
D212
bit 10 to bit 13).
The comfort reference value application uses the value to select a
preset reference value-deceleration ramp.
