Always obtain the original builder’s 900 parameter list from the machine’s electrical schematic or a full SRAM backup file ( .000 extension).
: After entry, set PWE back to 0 and press RESET . For many 900-series changes, a full power cycle (OFF/ON) is required to initialize the new options. Critical Maintenance Tips fanuc ot 900 parameter list
The turret solenoid clicked once.
Based on technical documentation, here is a snapshot of what these bits actually control: Description Functionality Unlocked CANNED CYCLE Enables standard G-code cycles like G81/G83. 900 G10 PROGRAM INPUT Allows software to update offsets automatically. 900 INCH / METRIC Toggle between imperial and metric measurement systems. 901 TAPE MEMORY Controls memory capacity (from 20M to 320M). 901 CHAMFER/RADIUS Enables corner rounding/chamfering G-codes. 902 CONSTANT SURFACE Allows the spindle to adjust speed based on diameter. 902 CUSTOM MACRO A Unlocks the ability to use variables and logic. 903 Enables the dynamic buttons below the CRT screen. 904 Changes the system text (Japanese, German, Spanish, etc.). How to "Unlock" These Settings Always obtain the original builder’s 900 parameter list
These parameters (often referred to as ) are crucial because they activate features not standard on every machine, such as advanced conversational programming, extended memory, custom macros, or specific canned cycles.

Enables canned cycles for drilling/boring (G80-G89). Bit 4 (THD): Enables thread cutting cycles (G76, G92).
