Enabling advanced programming flexibility, such as , interrupt functions, and specialized communication protocols (Ethernet/IP, Profibus, or FL-net configurations), relies on setting these parameters. How to View and Backup 9900 Parameters

Stored stroke limits act as electronic software fences to prevent the machine tool or spindle from crashing into the physical ends of the travel guides.

Sets the stop bits, baud rate, and handshaking protocols for standard serial communications. 2. Axis Control and Coordinate Systems (1000–1200) NC Parameters, Pitch Error Compensation, Tool Offsets, Macro

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
