Control of the Motion Control Kernel
Control of the basic drive functions implemented in the Motion Control Kernel is carried out by
means of
• direct specification of the control words, for example via a master control unit also connected
to the fieldbus.
• For this purpose, the control word inputs can be directly connected to the field bus interface
LP_MciIn respectively LP_CanIn.
• See the " MCK control word " chapter for a detailed description of the individual control bits.
• the specification of individual process signals at the L_MckCtrlInterface FB which are then ORed
with the control word.
Plausibility check
The process signals applied to the
L_MckCtrlInterface FB are logically linked by means of an OR logic
operation to the specified control word via the two control word inputs wInMckPosCtrl_1 and
wInMckPosCtrl_2 and, after a plausibility check, are output via the two control word outputs
wOutMckPosCtrl_1 and wOutMckPosCtrl_2 .
• The profile number, the operating mode, and the positioning mode are checked for plausibility.
• If implausibility is detected, only control bit information is output and the bFail output is set to
TRUE.
• The result of the plausibility check is provided as the wFailState output word and displayed in
C01299 .
The control words that are output, namely wOutMckPosCtrl_1 and wOutMckPosCtrl_2, constitute
the input information for the LS_MotionControlKernel system block.
Status information of the Motion Control Kernel
Output by the
LS_MotionControlKernel , the status words wMotionState1 and wMotionState2 also
constitute input information for the downstream L_MckStateInterface FB, which provides this
information to the application in the form of process signals.
