Case 1
：
When Execute changes from FALSE to TRUE, Busy changes to TRUE and one cycle later,
Done changes to TRUE and Busy changes to FALSE.
Case 2
：
When an error occurs during the instruction execution, Error changes to TRUE and ErrorID
shows corresponding error code. Meanwhile, Busy changes to FALSE. Error changes to FALSE
when Execute changes from TRUE to FALSE.

Function
DMC_SetStartPosition instruction sets the start positions of 8 axes of G code. After the instruction is
executed, the motion begins from the start positions of X, Y, Z, A, B, C, P and Q axes specified by the
instruction. For example, the start position of X axis is set to 10000 and G code is G0 X1000. So if G
code is to be executed, for X axis, the motion will begin from the position 10000 and get to 1000. The
firmware of V1.01 and above supports the function.
The start positions need not be set with the instructon if the DMC_CartesianCoordinate instruction is
used to perform G code. The DMC_CartesianCoordinate instruction will set the start positions
automatically.
