Hey guys,
The tool change process can not be completed since the position of the "key" on the spindle is not aligned with the "key" position on the tool. These two keys are supposed to work together to fix the position of the tool. While now they seem to be 90 degrees away from each other on the spindle. The following alarm came out:


Alarm 39-28.

Cause: The spindle drawbar is not clamped.

Remedy: Check the air supply to the drawbar.

Use the pendant DB Unclamp button to test the operation of the drawbar. Make sure the operator door is open, and the TOOL SETUP option is selected on the pendant. The correct solenoid/proximity switch signals are as follows.

SL_TL_UNCL OFF for Clamp and ON for Unclamp
PR_TL_CLMP ON for Clamp and Off for Unclamp
PR_TL_UNCL OFF for Clamp and ON for Unclamp


Do you have any thoughts on that?

Thanks a lot
