Main Variables
Name Data type Default Comment
MC_Axis000 _sAXIS_REF --- Axis Variable for the master axis,
axis 1.
MC_Axis001 _sAXIS_REF --- Axis Variable for the slave axis,
axis 2.
CamProfile0 ARRAY[0..36000] OF
_sMC_CAM_REF
--- This is the cam data variable.
The cam data variable is created
in advance on the Cam Editor of
the Sysmac Studio.
Pwr1_Status BOOL --- This variable is assigned to the
Status output variable from the
PWR1 instance of the MC_Power
instruction. This variable changes
to TRUE when the Servo is
turned ON.
