8.2.5
Consideration of residual value in case of external profile calculation
The
dnProfilePosition_p
input serves to transfer a profile position in [increments] to the
SB
. This will then be entered into the active profile data set selected in the
via the bits 24 ... 31.
For (external) calculations to be carried out before, the following blocks can be used in the FB Editor.
•
From version 12.00.00
onwards, these blocks automatically consider residual values and
modulo positions in case of a cycle length definition and correctly forward these internally:
The following blocks also automatically consider residual values and module positions and can be
used for forwarding the increment results of the previously mentioned blocks:
Block
Function
... converts a position value provided in the real unit of the machine into an internal
32-bit position value.
•
These FBs are available from version 12.00.00.
... provides the application with process inputs for controlling various basic functions
of the Motion Control Kernel.
Output of 16 parameterisable position signals with internal conversion of [unit] in
[increments]
•
These SBs are available from version 11.00.00.
Block
Function
... switches one of eight selectable input signals to the output.
... .switches between two input signals of "DINT" data type.
•
These function blocks are available from version 11.00.00.
:
• dnFreeIn1_p
• dnFreeIn2_p
These two inputs serve to transfer 32-bit signals from the I/O level to the application
level. The signals are available at the correspondent outputs of the application block
.
:
• dnPosProfilePosition
Selection of the target position in [increments] for the "table positioning"
application. The signal is available in the application level at the correspondent
output of the
application block.
