Tool changes are fast, and simple, but a brief description of the safety features built into the design of your manual tool changer is
important to understand how to troubleshoot your machine in the event of an error.
Tool changes can only be performed when the E
-
Stop is pressed, this electro
-
mechanically disables the spindle motors from turning
on during a tool change. The manual button located on the spindle has no voltage potential unless E
-
stop is engaged. This means
pressing the TC button while Estop is released will have no effect. As an additional safety measure, the VFD output is monitored and
must show zero output before energizing the tool changing solenoid.
Several criteria must be met to successfully perform a tool change. Sensors determine the 3 positions of the tool eject draw bar:
Draw bar retracted completely, no tool present.
Draw bar middle, tool present (locked)
Draw bar extended, tool ejected
The spindle drive requires the tool locked signal before allowing the spindle to operate.
THE SPINDLE MUST NOT BE TURNED ON
WITHOUT TOOL/TOOL HOLDER PRESENT.
Operation of the spindle with the drawbar in the extended, or fully retracted position will
lead to damage to your spindle, circuit wiring is designed to prevent operation of the machine unless a tool is present.
