ATC “In”
Is a limit switch that detects that the ATC has advanced all the way forward to the spindle.
4.4.5
ATC “Out”
Is a limit switch that detects that the ATC has retracted all the way back from the spindle.
4.4.6
Tool “Unclamp”
Is a limit switch that detects that the tool unclamp mechanism is in the unclamped state. If this limit
switch is not set or functioning properly, there is the potential that the draw bar could get friction welded
to the air cylinder adjusting screw. This switch is triggered only when you are physically loading a tool in
and out of the spindle. Pressing the green button on the head puts the machine in this state.
