Using the emergency stop signal effectively enables the design of safe
machine tools.
The emergency stop signal is provided to bring a machine tool to an
emergency stop. It must be input to the Power Mate i, servo amplifier,
and spindle amplifier. An emergency stop signal is usually generated by
closing the B contact of a pushbutton switch.
When the emergency stop signal (*ESP) contact is closed, the Power
Mate i enters the emergency stop released state, such that the servo and
spindle motors can be controlled and operated.
When the emergency stop signal (*ESP) contact opens, the Power Mate
i is reset and enters the emergency stop state, and the servo and spindle
motors are decelerated to a stop.
The Power Mate i must be supplied with an emergency stop signal from
either the built–in I/O module or the I/O module supporting the FANUC
I/O Link.
