Fanuc Ot 900 Parameter List
| Bit | Function | Value | |-----|----------|-------| | #1 | External message display | 1 = Enable | | #0 | Graphics display | 1 = Enable |
If you are dealing with a specific 900-series alarm, such as an alarm related to the , you may need to check the axis settings alongside the options.
: Parameters 900+ are bit-based (0 to 7). Changing these usually requires a machine restart to take effect. Google Groups Fanuc 0-T 900 Parameter Reference Table fanuc ot 900 parameter list
Because the 900-series parameters dictate hardware options, the control requires specific authorization steps before accepting changes.
Increases program storage memory (from 20m up to 320m+). | Bit | Function | Value | |-----|----------|-------|
He worked down the list like a bomb tech disarming a legacy device. 901, 902, 903—each one a buried decision about servo amplifiers, PMC allocation, whether the E-stop was N.C. or N.O.
Enables cylindrical interpolation (G07.1) for rotary axis milling. Bit 4: Activates tool geometry and wear offsets. Parameter 916: Communication and Interface Google Groups Fanuc 0-T 900 Parameter Reference Table
You must set the Parameter Write Enable (PWE) to 1 to change these. It is found under the SETTING screen. Note: You may need to restart the machine to save changes.
Some option bits are mutually exclusive. For example, Custom Macro A (parameter 902 bit 6) and Custom Macro B (parameter 932 bit 3) cannot be active simultaneously on older OT controls. Attempting to enable both may lead to unpredictable system behavior.
| Bit | Function | Value | |-----|----------|-------| | #7 | External tool compensation | 1 = Enable | | #6 | Automatic tool compensation | 1 = Enable | | #5 | Tool shape wear compensation | 1 = Enable | | #0 | Menu programming | 1 = Enable |
