Fanuc Ot 900 Parameter List Page

For instance, if you set parameter 6071 = 91, then programming "M91" will call and execute macro program O9001.

Below is a list of common 900-series parameters for the Fanuc 0-T control. Each parameter consists of 8 bits, labeled 7 to 0 from left to right. Google Groups Function Enabled (when set to 1) Canned Cycles : Enables standard cycles like G81-G89 G10 Programmable Data Input : Allows tool offsets via G-code Manual Pulse Generator (MPG) : Enables handwheel control Inch/Metric Conversion : Toggle between measurement systems Tape Memory Addition (120M) : Increases program storage Chamfering/Corner Radius : Enables automatic R and C programming Multiple Repetitive Cycles : Enables G70-G76 cycles Constant Surface Speed (CSS) : Enables G96/G97 functionality Custom Macro A : Enables basic macro programming Actual Spindle Speed Output : Displays real-time RPM on CRT : Enables the row of keys below the CRT screen Language Selection : 0: Japanese, 1: German/French, 3: Italian, 4: Spanish Important Safety Warning

Before modifying any parameter, you must enable parameter writing. This critical safety step prevents accidental changes during normal operation: fanuc ot 900 parameter list

Press the SYSTEM key and search for the specific parameter (e.g., 901).

| Bit | Function | |------|-----------| | 7 | 4th axis (A axis) present: 0=no, 1=yes | | 6 | 4th axis rotary (indexing table) | | 5 | 4th axis contouring (simultaneous movement with X/Z) | | 4 | 4th axis home direction | | 3 | Axis name display (0 = A, 1 = B) | | 2-0 | Step motor vs. servo motor | For instance, if you set parameter 6071 =

The second category, and the focus of this article, is the (also known as "confidential parameters" or "secret parameters"). Fanuc historically treated these parameters as proprietary information, intentionally withholding their documentation from public manuals. These 8‑bit parameters function as software switches that enable or disable specific CNC features—from basic functions like metric/inch conversion to advanced capabilities like custom macro programming.

Writing a random 900 parameter set from another machine of the same model will usually not work . These values are matched to the specific hardware and PMC ladder of your exact lathe. Google Groups Function Enabled (when set to 1)

| Bit | Function | Value | |-----|----------|-------| | #4 | Special G-code input | 1 = Enable |
