Fanuc 9900 Parameter List ((full)) -

The exact meaning depends on the . Below is a representative list based on older Series 0/16/18/21 maintenance manuals.

They control how axes interact when executing synchronized waiting codes (M-codes).

Detailed lists for specific control models are often found in official , such as: fanuc parameter detail 9900 to 9998 | Practical Machinist fanuc 9900 parameter list

Because these parameters dictate the core capabilities of the control, they are usually locked behind strict write-protection layers. Common FANUC 9900 Parameter Categories

Note: Some critical parameters (such as servo motor changes or axis configuration updates) will display a "P/S 000 TURN OFF POWER" alarm. If this appears, cycle the main breaker toggle on the CNC enclosure to allow the bootloader to register the changes. Critical Safety Warning Concerning "9000 Series" Parameters The exact meaning depends on the

Historically, FANUC used the 9900 series (specifically 9900 to 9990) to store binary data that unlocks purchased software options like 5-axis simultaneous machining, high-speed look-ahead (AICC II), rigid tapping, or custom macro execution.

Suppose an X-axis servo motor fails. The replacement is a newer model. The machine builder’s parameter list says: Detailed lists for specific control models are often

: These parameters often do not appear on the standard parameter screen and are instead hidden within a diagnostic screen.

: Use the SYSTEM function key and then the PARAM soft key to find the 9900 series.
