MC_ExtSetPointGenEnable
The external set value generator of an axis can be switched on with the function block MC_ExtSetPointGenEnable. Subsequently, the axis takes over the set value specifications from its cyclic axis interface ( fExtSetPos, fExtSetVelo, fExtSetAcc and nExtSetDirection)

Execute : BOOL;
Position : LREAL;
PositionType : E_TargPosType;
END_VAR
Execute : The command is executed with rising edge.
Position : Position for target position monitoring. Setting of this position does not mean that the axis moves to this position, for which only the external set value generator is responsible. Setting of this position activates target position monitoring, and the flag In target position becomes TRUE, as soon as this position is reached.
PositionType : Position type
