Tool Changer logic
When a tool change command is received, the tool changer logic works in the followings steps:
1. Spindle is turned OFF and the system waits for the spindle to stop as per the spindle "Spin down
delay" value in the spindle settings.
2. The system checks if the current tool in the spindle is setup in a slot is the F4-Tools screen, else
gives an error.
3. The system checks if the tool to load is setup in a slot is the F4-Tools screen, else gives an error.
4. Z-Axis moves up to the homing position.
5. "Tool Changer - Output 1" goes HIGH to move Dust Hood UP, then the system waits for 6
seconds for the "Tool Changer - Input 2" (Dust Hood UP OK) signal to go HIGH, else gives an
error.
6. "Tool Changer - Output 1" goes LOW.
7. "Tool Changer - Output 3" goes HIGH to move Tools Tray UP, then the system waits for 6
seconds for the "Tool Changer - Input 4" (Tools Tray UP OK) signal to go HIGH, else gives an
error.
8. "Tool Changer - Output 3" goes LOW.
9. X & Y-Axis moves to tool unload position.
10. "Chuck Clamp M10/M11" goes HIGH to unclamp the tool, then the system waits for 6 seconds for
the "Tool Changer - Input 1" (Spindle draw bar Status) signal to go HIGH, else gives an error.
11. X & Y-Axis moves to the new tool load position.
12. "Chuck Clamp M10/M11" goes LOW to clamp the tool, then the system waits for 6 seconds for the
"Tool Changer - Input 1" (Spindle draw bar Status) signal to go LOW, else gives an error.
13. Axis moves to slide out the new tool.
14. "Tool Changer - Output 4" goes HIGH to move Tools Tray DOWN, then the system waits for 6
seconds for the "Tool Changer - Input 5" (Tools Tray DOWN OK) signal to go HIGH, else gives an
error.
15. "Tool Changer - Output 4" goes LOW.
16. "Tool Changer - Output 2" goes HIGH to move Dust Hood DOWN, then the system waits for 6
seconds for the "Tool Changer - Input 3" (Dust Hood DOWN OK) signal to go HIGH, else gives an
error.
17. "Tool Changer - Output 2" goes LOW.
INFORMATION: All input & output signals can be easily inverted by selecting the input or output in
the list and pressing the space-bar key on the keyboard to invert the signal. These settings are
automatically saved.
INFORMATION: Make sure to assign each tool into a tool slot in the F4 - Tools & Work offset
screen else on a tool change command if the tool is not set in a slot you will get a tool error alarm.
