Fanuc Ot | Reference Parameter Better [exclusive]

Establishing the "Home" position is perhaps the most critical task after a battery failure or memory loss. Soft Limits (700-707)

| Problem | Typical Cause | "Better" Solution | | :--- | :--- | :--- | | | Ref point set too far positive on Z | Set Ref point 3mm inside soft limit | | Turrets indexes at wrong height | Grid shift (Param 0010) is corrupted | Use Diagnostic 300 to reset to known value | | Slow homing speed | Decel feedrate (P700) is too low | Increase to 200-300, but decrease approach speed | | Inconsistent home position (±5 microns) | Dirty limit switch or cable noise | Clean the switch; DECEL feedrate is too high | fanuc ot reference parameter better

Ensure the physical cam (deceleration dog) is clean. The 0T looks for the deceleration signal first, then the next encoder grid mark. Establishing the "Home" position is perhaps the most
