 Purpose
Retrieves the current value of the target position.
 Parameters
Name Data Type
CardNo
NodeID
SlotID
pos
 Example
U16 CardNo=0;
U16 NodeID =1;
U16 SlotID = 0;
I32 pos=0;
I16 status= _DMC_01_get_target_pos (CardNo, NodeID, &pos);
NOTE
※ After issuing a motion command, if you are relying on _DMC_01_get_target_pos to
return the pos so you can decide the next step, put in a delay of 10~100ms (this value
can be adjusted based on CPU performance and programming approach) before
executing _DMC_01_get_target_pos to ensure that the data is correct.
