Fanuc 9900 Parameter List Instant
To change any parameter in the 9900 range, you must place the control into mode. Follow this exact sequence to prevent system faults: Step 1: Backup the CNC System
| Parameter | Description | Source | | :--- | :--- | :--- | | | Number of controlled axes (typically). For a lathe, this is often "2" (X and Z). For a milling machine, it is often "3" or "4" (X, Y, Z, and possibly a 4th axis). Also used in servo motor configuration to identify single, dual, or triple-axis drives. | | | 9920.0 | Fixed cycles . Enables the use of standard canned cycles (e.g., G81, G83). | | | 9920.1 | Tool offset input with G10 . Allows the G10 command to be used to input tool compensation values. | | | 9920.2 | Manual Pulse Generator (MPG) feed . Enables MPG (handwheel) operation. | | | 9920.3 | 1 MPG control . Activates control using a single manual pulse generator. | | | 9920.4 | Spindle S4/S5 analog output . Enables analog output for S4/S5 spindle commands. | | | 9920.5 | Inch/Metric conversion . Activates the ability to switch between programming units. | | | 9921.0-9921.4, 9921.7 | Program storage capacity . These parameters define the available memory for part programs. Options include 640m, 320m, 160m, 80m, 40m, and 20m. | | | 9922.2 | Constant surface speed control . Enables the CSS function for turning applications (G96). | | | 9922.5 | Stored pitch error compensation . Activates the system to compensate for the mechanical inaccuracies of the ballscrew (leadscrew). | | | 9922.6 | Custom Macro A . Enables the use of FANUC's Macro A programming language. | | | 9923.7 | Background editing . Allows the operator to edit one program while running another. | | | 9924.0-9924.5 | Display language . These parameters control the system's display language (Japanese, Chinese, German, French, Spanish, Italian, Korean). | | | 9925.0 | Helical interpolation . Enables 3-axis simultaneous motion for circular interpolation with a third axis (helical milling). | | | 9925.1 | 300 work coordinate systems . Expands the number of available work coordinate systems (G54-G59) to 300. | | | 9926.3/ .4/ .5 | Tool offset memory expansion . Increases the number of available tool offset registers (64, 99, or 200). | | | 9927.6/ .7 | Cutter compensation . Enables Cutter Compensation C (Type C) and B (Type B), which are used for contouring. | | | 9930.1 | Program restart . Activates the capability to restart a machining program from a specific sequence number. | | | 9931.2 | Rigid tapping . Enables the spindle motor to operate as a position-controlled servo for synchronized tapping. | | | 9932.1 | Scaling . Allows for the program to be machined at a different scale (enlarged or reduced). | | | 9932.2 | Coordinate rotation . Enables a transformation to rotate the coordinate system, useful for angled machining features. | | | 9932.4 | Tool life management . Activates the system that monitors and controls the usage time of each cutting tool. | | | 9933.1 | Polar coordinate command . Allows programming in polar coordinates (radius and angle). | | | 9933.5 | 4-axis simultaneous control . Enables the ability to command four axes to move at the same time. | | | 9933.7 | Custom Macro B . Enables the more advanced Macro B programming language. | | fanuc 9900 parameter list
Modifying these parameters improperly can cause system alarms, void your warranty, or lock your control. This guide outlines the structure, common functions, and safety protocols for dealing with the FANUC 9900 parameter list. Understanding FANUC 9900 Series Parameters To change any parameter in the 9900 range,
Parameters like 9927.2 (3-axis simultaneous), 9927.3 (Additional axis), and 9928.1 (Reference return) define motion capabilities. For a milling machine, it is often "3"
