The DRT/DT type of MASTER-K120S series support 2 axes of positioning function. The purpose of positioning function is to 

transfer the moving objects by setting speed from the current position and stop them on the setting position correctly. And it also 

control the position of high precision by positioning pulse string signal as it is connected to various servo running devices or 

stepping motor control running devices.
