8.2.1 MCK control word
The motion control function implemented in the LS_MotionControlKernel system block can be
controlled via the wMotionCtrl1 and wMotionCtrl2 control words. Together, both control words
form a 32-bit control double word which serves to control the entire MotionControlKernel. All
motion profiles in the various operating modes can be operated via this interface.
For direct control via a fieldbus system, the two control words can be triggered by the field bus via
a port block. In addition to a few other signals (e.g. limit switch, speed override) that are connected
to the digital inputs of the inverter, all control signals can therefore be activated/deactivated via the
fieldbus used (CAN, PROFIBUS, etc.).
As an alternative to this, changes to the individual control bits or bit fields (e.g. for specifying the
profile number) can also be carried out via separate process inputs provided by the
L_MckCtrlInterface
function block. The control words wOutMckPosCtrl_1 and wOutMckPosCtrl_2
output by this function block constitute the input information for the LS_MotionControlKernel
system block in this case.
