Case 3： When Execute changes from FALSE to TRUE, Busy and Active change to TRUE. One cycle
later, Done changes to TRUE and DataType and Data show corresponding data values. After
Done changes to TRUE, Busy and Active change to FALSE in the same cycle. When Execute
changes from TRUE to FALSE, Done changes from TRUE to FALSE and DataType and Data
retain original values. If Error changes to TRUE, the values of DataType and Data will be
cleared to 0.
Case 4： The input parameter value is illegal such as axis number: 0 before the
DMC_ReadParameter_Motion instruction is executed. When Execute changes from FALSE to
TRUE, Error changes to from FALSE to TRUE and ErrorID shows corresponding error code.
When Execute changes from TRUE to FALSE, Error changes from TRUE to FALSE and the
content of ErrorID is cleared to 0.
Function

DMC_ReadParameter_Motion reads a slave parameter value. Users can specify the index and subindex
of the parameter which is to be read.
