Chapter 2
Operating the Control
2-22
Press the red <EMERGENCY STOP> button on the MTB panel (or any other
E-Stop switches installed on your machine) to stop operations regardless of
the condition of the control and the machine.
ATTENTION: To avoid damage to equipment or hazard to
personnel, your system installer should connect the
<EMERGENCY
STOP> button so that pressing the button opens the circuit
connected to the E-STOP STATUS terminal on the control’s
subprocessor board. This disables the axis drives and the
spindle drive circuits, provided both are connected to this
terminal. See your integration manual or the documentation
prepared by your system installer for details.
If equipped with the standard MTB panel, the following occurs
automatically after pressing the
<EMERGENCY STOP> button:
the control displays “E-STOP” in the message area. This indicates that
the control is in the emergency stop state
the red light in the <CYCLE STOP> button lights up to indicate that the
control is in the feedhold state
power to all axis drive motors is turned off
Important: If you press the <EMERGENCY STOP> button while a part
program is running, program execution can be resumed at the point of
interruption. See the mid-program start feature described in chapter 7.
After the control has entered the emergency stop state, you must perform
an E-Stop reset before program execution can continue.
ATTENTION: Before resetting the emergency stop state, first
locate and eliminate the cause of the emergency stop.
If the <EMERGENCY STOP> button is locked in the pressed position, it must
be released before the emergency stop state can be reset. You can release
the locked button in different ways depending on its type. With the
standard MTB panel, turn the button clockwise until it pops out.
