Emergency Stop Button [EMERGENCY STOP]
The EMERGENCY STOP button is used to stop the
machine immediately, for example when an emergency
requiring an immediate machine stop occurs.
This button is also used to turn off the power supply on
ending operation.
When the EMERGENCY STOP button is pressed, the power supply to the circuits that control the
axis movements and spindle rotation is shut off and the machine stops.
To reset the emergency stop state, pull out the EMERGENCY STOP button from the pushed and
locked position then press the NC power switch
(ON).
Depending on the machine model and specifications, there may be an emergency stop
button at more than one location.
In this case, all of these emergency stop buttons have the same function and pressing any
one of them stops the machine. To reset the emergency stop state, it is necessary to pull
out all the emergency stop buttons from the pushed and locked position.

switch which is actuated if the carriage comes too close to the tailstock, establishing the
emergency stop state and preventing further axis movement.

WARNING
The emergency stop buttons are used to stop all operations in the event
of an emergency. Memorize the locations of the emergency stop buttons
so that you can press one immediately from any location and at any time
while operating the machine. If there is an obstruction preventing
operation of an emergency stop button it will not be possible to press it
immediately when an emergency occurs and this could cause accidents
involving serious injuries or damage to the machine.
