The most dangerous part of a 10M reset is the servo initialization. The manual details parameters 1010 through 1023 (Number of axes), 1420 (Rapid traverse speed), and 1422 (Maximum cutting feedrate).
The Fanuc 10M control system is a legend in the manufacturing world. While it is decades old, thousands of these robust systems still power milling machines and machining centers globally. However, for a maintenance technician or operator facing a "Not Ready" alarm or a machine that has lost its memory, the Fanuc 10M Parameter Manual is the single most important document in the shop.
