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
control bits.
 the specification of individual process signals at the
then ORed with the control word.
Plausibility check
The process signals applied to the
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
Status information of the Motion Control Kernel
