Fanuc Ot 900 Parameter List Extra Quality -

| Bit | Name | Function | | :--- | :--- | :--- | | 0 | HLP | Help function (on-screen assistance) | | 1 | SCH | Schedule program (multi-job management) | | 2 | TAP | Tape mode editor | | 3 | LDP | Load / unload parameter (PMC ladder transfer) | | 4 | MDC | Manufacturing data capture (production counters) | | 5 | DRV | Driver monitor (servo waveform display) | | 6 | PRT | Parameter trace (diagnostic logging) | | 7 | ALM | Alarm history storage |

Unlike standard decimal or integer parameters, the 900-series are . Each parameter consists of 8 bits (labeled 0 through 7), where setting a bit to 1 enables a specific function and 0 disables it. Core Option Parameter Examples

If you have a or 0T-TT (Twin Turret), the parameter list for the 900 range can differ significantly.

The machine will trigger a flashing 100 P/S ALARM (Parameter Write Enable alarm). This is normal. fanuc ot 900 parameter list

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.

Locate the setting screen containing . Type 1 and press the INPUT key.

The 900 series is interesting because it reveals that

The 900-series parameters are bit-specific. Each parameter consists of 8 bits, read from left to right as . Parameter 900: Axis and Basic Control Bit 7 : Tool life management function. Bit 6 : Axis control by PMC (Programmable Machine Control). Bit 5 : Control of 4 axes simultaneously. Bit 4 : Control of 3 axes simultaneously. Bit 3 : 4th axis control function. Bit 2 : 3rd axis control function. Bit 1 : Linear interpolation on the 3rd axis. Bit 0 : Positioning on the 3rd axis. Parameter 901: Memory Expansion and Program Storage Bit 7 : Memory expansion to 40 meters of tape equivalent. Bit 6 : Memory expansion to 80 meters of tape equivalent. Bit 5 : Memory expansion to 120 meters of tape equivalent. Bit 4 : Memory expansion to 320 meters of tape equivalent. Bit 3 : Number of registerable programs expanded to 400. Bit 2 : Number of registerable programs expanded to 200. Bit 1 : Background editing capability. Bit 0 : Run hour and parts counter display. Parameter 902: Canned Cycles and Interpolation Bit 7 : G10 Programmable data input. Bit 6 : G22/G23 Stored stroke limit checking. Bit 5 : G27-G30 Reference position return check. Bit 4 : G31 Skip function (used for touch probes). Bit 3 : G34 Variable lead thread cutting. Bit 2 : G39 Corner circular interpolation. Bit 1 : G70-G76 Canned cycles for turning/facing. Bit 0 : G92 Constant surface speed control. Parameter 903: Advanced Coordinate and Spindle Functions Bit 7 : Tool geometry and wear compensation separation. Bit 6 : Number of tool offsets expanded to 32 pairs. Bit 5 : Number of tool offsets expanded to 64 pairs. Bit 4 : Tool nose radius compensation (G40/G41/G42). Bit 3 : Workpiece coordinate system selection (G54-G59). Bit 2 : Custom Macro B option. Bit 1 : Custom Macro A option. Bit 0 : Spindle orientation control. 🔍 How to Read and Edit Binary Bits When looking at a parameter screen, it displays like this:

Enter 900 and press NO. to go directly to the option parameters. The machine will trigger a flashing 100 P/S
