How to adjust tool change position
 During maintenance, we often need to replace the spindle motor, spindle or encoder. After disassembly and assembly, we need to reset the spindle positioning parameter 4077. The early FANUC system cannot diagnose, and can only rely on eye observation and a little debugging. In recent systems, the positioning angle can be observed through diagnosis 445. After the spindle positioning is corrected, the value of diagnosis parameter 445 is written into NC parameter 4073 4077; what if the value of diagnosis parameter 445 is always 0 or reset to 0 ?





Methods as below:
(1) After starting up, run M3S600 in MDI mode, and then execute M19 to check whether the diagnosis 445 parameter changes
(2) If the diagnosis parameter 445 is always 0 or the diagnosis parameter 445 is not displayed, check whether the NC parameter 3117#1 is 1



(3) If the diagnosis parameter 445 becomes 0 after pressing the reset button, check whether the NC parameter 4016#7 is 0



After the spindle positioning is corrected, write the value in diagnostic parameter 445 to NC parameter 4073 4077, and the spindle positioning can be set
