Tool Changer logic
During machine homing:
1. After all the axis of the machine have been homed as per the homing sequence the tool changer
logic will home the tool changer.
2. The tools will be retracted and the system will wait for as per the timeout period setup in the
Umbrella Toll Changer Settings.
3. Once retraced the tools will rotate until the homing sensor on the tools is not activated. IMPORTANT:
The home position of the tool changer must be marked as Slot "1".
4. Then the system will automatically rotate the tool to the last loaded position (empty tool slot).
When a tool change command is received, the tool changer logic works
