Precautions on modes and mode switching
NOTE
1 In MDI mode, the STL signal turns to "0" and the CNC stops as soon as the
commands entered via the MDI have been executed. But the SPL signal does not
turn to "1". Therefore, another command can be entered from the manual data
input unit under this condition.
