In actual processing, we may encounter the wrong orientation angle of the spindle of the machining center, resulting in the inability to change the tool. In this case, we can adjust it by adjusting the system parameters.
Step 1: First find the diagnosis page
What if the value of diagnostic parameter 445 is always 0 or is 0 after reset?
solutions:
(1) Perform a spindle rotation after starting up, such as: M3S500, and then execute M19 to check whether the diagnostic 445 parameter changes
(2) If the diagnostic parameter 445 is always 0, check whether the NC parameter 3117#1 is 1
(3) If the diagnostic parameter 445 becomes 0 after pressing the reset button, check whether the NC parameter 4016#7 is 0
Then find the 445 parameter:
There is a value in the 445 parameter, which represents the current angle of the spindle.
Step 2: We manually shake the motor of the tool changer arm to turn the tool changer arm to the position corresponding to the main shaft, that is, the tool changer arm is stuck on the main shaft. Then turn the spindle so that the spindle tool groove and the tool change arm tool groove are in a straight line.
Step 3: Then input the value in the 445 parameter to 4077 in the parameter page:
This is the adjustment step for FANUC system.
