Auxiliary Function Lock

Machine lock and Auxilixry function lock
To display the change in the position without moving the tool, use machine lock.
There are two types of machine lock: all–axis machine lock, which stops the movement along all axes, and specified–axis machine lock, which stops the movement along specified axes only. In addition, auxiliary function lock, which disables M, S, and T commands, is available for checking a program together with machine lock.
Press the machine lock switch on the operator’s panel. The tool does not move but the position along each axis changes on the display as if the tool were moving. Some machines have a machine lock switch for each axis. On such
machines, press the machine lock switches for the axes along which the tool is to be stopped. Refer to the appropriate manual provided by the machine tool builder for machine lock.
