NOTE
1 This switch must be opened in automatically, when
the operator exposes himself to danger, example
the observation working in the protection cover of
cutting part, and the working in the fence for danger
area. So, the enable switch must be hold at the
middle position avoiding the emergency stop. When
the operator does not expose himself to danger, this
switch is closed. So he does not have to hold the
enable switch at the middle position.
And this switch may be the switch for the detection
of fusing and attaching on the main operator’s
panel. When there is the switch, the protection
cover and the fence does not have to open for the
testing of fusing and attaching of enable switch.
2 The details connection of JD1A, JD1B (I/O Link) of
interface unit is eliminated.
