Fanuc 11m Parameter List

All critical data (parameters, programs, offsets) on a Fanuc 11M is stored in volatile SRAM memory that requires constant power from a backup battery when the main power is off. Losing battery power means losing everything. Replacing this battery is a straightforward but critical maintenance task.

: Sets program storage capacity (e.g., 100 or 200 programs). 9111 Bit #0 : Macro B option. 9116 Bit #0 : Enables the Part Counter feature. fanuc 11m parameter list

| Feature | Description | |--------|-------------| | | Unlike later Fanucs (0i/16i use 5-digit), 11M is strictly 0000–9999. | | Bit/Byte split | Some parameters are bit (0/1), some are byte (0–255), some are 2-byte (0–65535). The manual indicates format as B (bit), BY (byte), or 2BY (2-byte). | | No Parameter Write Enable (PWE) | On 11M, to edit parameters you must set PWE = 1 (parameter 0000 bit 0) and cycle power, or use MDI mode + parameter write enable switch (if wired by MTB). | | Separate CNC vs. Servo Parameters | The 11M splits them: 0000–0999 (CNC general), 1000–1999 (axis config), but servo tuning is in 0100–0899. | | Option parameter unlocking | Many option bits (e.g., 4th axis, helical, scaling) are protected; changing them requires a special password (often series-specific, not user-changeable without Fanuc hardware key). | All critical data (parameters, programs, offsets) on a
