Mazak Alarm 258 TNo. MISMATCH
Since ATC has been aborted by pressing the emergency stop button in the middle of the ATC process, the number of the tool mounted on the milling head is different from that displayed on the NC display.
Check and remedy
Change the “TURRET TOOL” number displayed in the DIAGNOSIS display to the number of the current tool (that is, the parenthesized numerals in alarm messages).
