Case 1
：
When Execute changes from FALSE to TRUE, Busy changes to TRUE. When the instruction
execution is completed, Done changes to TRUE and Busy changes to FALSE. When Execute
changes to FALSE, Done changes to FALSE.
Case 2
：
When an error occurs, Error changes to TRUE and ErrorID shows corresponding error code.
When Execute changes from TRUE to FALSE, Error changes to FALSE and the value of
ErrorID is cleared to 0.

Functions
DMC_CamSet is used for making the set cam point information effective. At first, use the
DMC_CamWritePoint instruction to set corresponding cam point information in an electronic cam
table. Then execute the DMC_CamSet instruction to make the new cam point information effective.
If the DMC_CamSet instruction is executed after the MC_CamIn instruction is executed, the cam
curve after being modified will be effective in the next cycle.
If the DMC_CamSet instruction is executed before the MC_CamIn instruction is executed, the cam
curve after being modified will take effect immediately.

Precaution
If DMC_CamSet is used for making a modified cam curve effective, make sure that the cam curve is
called for use by one MC_CamIn instruction at most. If the cam curve is called for use by multiple
MC_CamIn instructions, the timing for making the set cam curve effective is not sure after
DMC_CamSet is executed.
