Monitor Test
Digital Output checks whether the digital output (DO) components function properly.
You can switch each DO component to ON and check the operation separately, which helps you judge
which component functions normally.
You can operate all components at one time in the Digital Output Test. If you open the interlock while
a motor test is being executed, the operation of each component will be stopped.
Note: Except for 010-001, 042-001, 042-002, set LVPS 24V to On (041-001) first.
