: To change most parameters, set the control to MDI mode and change the PWE bit to 1 .
Power off the CNC completely, wait a few seconds, and turn it back on. fanuc ot reference parameter better
| Step | Action | | :--- | :--- | | 1 | Set (dog method). | | 2 | Set DZR bit = direction from home to limit switch (e.g., 1 for negative direction). | | 3 | Set DLx bit = 0 if switch is Normally Open (activates to 1 when on dog), else 1. | | 4 | Manually move axis 50mm past the dog toward the limit. | | 5 | Press ZRN + axis direction (per DZR bit). Axis rapids, hits dog, decelerates, creeps, finds grid. | | 6 | Adjust Grid Shift (param 000 for X, 001 for Z) to fine-tune zero point. | | 7 | Record final mechanical position (scribe reference marks on axis). | : To change most parameters, set the control
If the machine has mechanical play, the reference point may appear to shift. Adjusting backlash parameters ensures the axis settles in the same spot every time. 3. Setting a Second Reference Point | | 2 | Set DZR bit = direction from home to limit switch (e
