An emergency stop condition normally occurs when the system overheats, a
fault occurs, or when the Emergency Stop button on the
MILLPWR operator
console is pressed. The AMI gives you the option of adding table limit switch-
es and another Emergency Stop button into the system’s emergency stop cir-
cuitry. When an emergency stop is activated,
MILLPWR will immediately shut
off the system’s motors, shut off any external devices that are connected to the
AMI, and stop all machine movement.
If you are not using the J2 or J4 connec-
tor on the AMI, you must wire a jumper
at this time to close the circuitry.
Otherwise, when you power on
MILLPWR
and the AMI, an emergency stop condi-
tion will automatically occur and
neither system will run.
