Main Variables Used in the Programming Samples
Variable name Data type Default Comment
MC_Axis000 _sAXIS_REF --- This is the Axis Variable for axis 0.
MC_Axis000.MFaultLvl.Active BOOL FALSE TRUE when there is a minor fault level error for
axis 0.
MC_Axis000.Details.Homed BOOL FALSE TRUE when home is defined for axis 0.
Pwr_Status BOOL FALSE This variable is assigned to the Status output
variable from the PWR instance of the
MC_Power instruction. It is TRUE when the
Servo is ON.
StartPg BOOL FALSE When StartPg is TRUE, the Servo is turned ON
if EtherCAT process data communications are
active and normal.
ReExeSw BOOL FALSE This variable is used to re-execute the instruc-
tion.
Mv_Abs_Ex BOOL FALSE This variable is used to execute the
MC_MoveAbsolute (Absolute Positioning)
instruction. It is used in ST programming.
Hm_Ex BOOL FALSE This variable is used to execute the MC_Home
instruction. It is used in ST programming.
