How to access/write 900 parameters (common method) – they are machine-builder specific
You cannot change parameters while the machine is running or in Jog mode. While every machine is configured differently by the
While every machine is configured differently by the builder (OEM), here are the most common bit definitions for the 0T-A, 0T-B, and 0T-C controls: Parameter 900 Canned Cycles (G70–G76) Bit 1: G70-G76 Canned Cycles (alternate) Bit 2: Circular Interpolation (G02/G03) Bit 3: Sub-program calls (M98/M99) Parameter 901 Bit 1: Tool Geometry/Wear Offsets Bit 3: Custom Macro A Bit 6: Inch/Metric Conversion (G20/G21) Parameter 902 Bit 1: Constant Surface Speed Control (G96/G97) Bit 5: Background Editing Parameter 907 Bit 0: 48 pairs of tool offsets Bit 3: 64 pairs of tool offsets 📂 The Importance of the "Parameter Sheet"
Changing these without a backup can render your machine inoperable. Always document your original values before making edits. 🛠️ How to Enable Parameter Writing
