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 LS_MotionControlKernel
. This will then be entered into the active profile data set selected in the
MCK control word
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
L_ConvUnitsToIncr_1
L_ConvUnitsToIncr_2
L_ConvUnitsToIncr_3
... 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.
L_MckCtrlInterface_1
... provides the application with process inputs for controlling various basic functions
of the Motion Control Kernel.
LS_ParFreeUnit
LS_ParFreeUnit_2
Output of 16 parameterisable position signals with internal conversion of [unit] in
[increments]
• These SBs are available from version 11.00.00.
Block Function
L_Mux_1
... switches one of eight selectable input signals to the output.
L_SignalSwitch32_1
L_SignalSwitch32_2
L_SignalSwitch32_3
... .switches between two input signals of "DINT" data type.
• These function blocks are available from version 11.00.00.
LA_SwitchPos
/ LA_TabPos:
• 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
LA_SwitchPosIn
or LA_TabPosIn.
LA_TabPos
:
• 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 LA_TabPosIn
application block.
