• Replacing a Motherboard (Main CPU): A new board arrives with factory defaults. It will not run your specific lathe.
• Battery Failure (SRAM Loss): When the backup batteries die, the parameter list vanishes. The machine becomes a brick.
• Performance Tuning: A technician updating servo gains to reduce cycle times.
• Adding Options: Activating a new software option (e.g., Helical interpolation or AICC) requires changing specific bit parameters.

A. System Configuration (The "Brain")

• Bit 0: Determines if the machine is a Mill (M) or Lathe (T).
• Bit 2: Determines the number of axes.
• Why it matters: If this is wrong
