Introduction The Fanuc OT series uses option parameters in the 900–923 range (commonly called “900 parameters”) to enable optional features and functions on O/T-series controls. Each parameter is an 8-bit value where each bit (bit0…bit7) typically toggles a specific option (displayed as binary 76543210). Below is a concise, practical reference you can use to identify and set OT-900 option bits safely.
| Bit | Function | |------|-----------| | 7 | Turret type: 0 = hydraulic, 1 = electric servo (live tooling) | | 6 | Tool count (0 = 8 tools, 1 = 12 tools) | | 5 | Bi-directional indexing | | 4 | Shortest path indexing | | 3 | Random vs. fixed tool selection | | 2 | Tool offset memory (0 = 32 pairs, 1 = 99 pairs) | | 1 | Tool life management enable | | 0 | Tool wear compensation type | fanuc ot 900 parameter list
Unlike standard parameters (like feed rates or offsets), the 900 series parameters are binary. Each parameter consists of 8 bits (0 or 1), where each bit acts as a "toggle" for a specific software option. Introduction The Fanuc OT series uses option parameters
