Fanuc 9900 Parameter List Now

This guide explains the Fanuc 9900 parameter list, how parameters are organized and used, and practical tips for working with them safely and effectively. It’s written for CNC technicians, programmers, and engineers who need a clear, actionable reference.

Use these categories to locate settings quickly. Exact parameter numbers may vary by Fanuc 9900 firmware and machine builder options; always consult your machine-specific manual.

Based on typical Fanuc configurations, the bits for parameter 9900 often control foundational G-code and hardware behaviors: Canned Cycles Bit 1: G10 Program Input of Offset Bit 2: Mechanical Handle Feed Bit 3: Manual One Pulse Generator Control Bit 5: Inch / Metric Conversion Bit 6: Special G-Code Security and Access fanuc 9900 parameter list

An alarm will usually occur once this is enabled, which is normal. Navigate to the 9900 Series Search for "9900" using the [SRH] soft key or cursor keys. Unlocking 9xxx Parameters In some controls (like the i30), parameter 3202 bit 4

When editing macro programs (O9000 - O9999), always leave comments inside the code. This will save you (or the next technician) hours of head-scratching when troubleshooting. Conclusion

FANUC parameters are generally organized by function. To understand where the 9900 series fits, look at the standard memory map: Exact parameter numbers may vary by Fanuc 9900

The 9000 series parameters, including and especially the 9900 range, are known by several names: "Option Parameters," "Function Parameters," or "Secret Parameters." Unlike standard parameters, these are not documented in the standard manuals provided with a machine tool. This is because their values directly activate specific, purchasable software functions and define the basic hardware configuration of the control, such as the number of axes.

Similarly, this parameter controls the protection for programs in the 9000 to 9099 range on memory cards or USB devices. 4. Custom Cycle Macro Parameters

Change from 0 to 1 (this will trigger an alarm, which is normal).

Modifying 9000-series parameters without a valid option authorization code from Fanuc can lock your controller or cause severe machine malfunction. Always backup your current parameters ( backup) before attempting changes. 1. Function and Purpose
