Parameters in the 0500 and 0700 series are often used to compensate for mechanical inaccuracies. Leadscrew pitch error compensation values are stored here, allowing the control to adjust the commanded position to account for physical wear in the ball screw, ensuring micron-level accuracy. 3. Reference Point Return (Grid Shift)
: Used to set the maximum allowable spindle speed for different gear ranges. Lowering these can protect older bearings or limit speed for specific chucking setups. eMastercam.com 5. Production Tracking Part Counting Variable #3901 : This system variable tracks the part count. Parameter 6700 #0
Over time, mechanical wear introduces play into the ball screws. The FANUC 0T handles this through software compensation. fanuc ot reference parameter better
After the modifications are complete, the operator must return to the setting screen and change the "PARAMETER WRITE" (PWE) back to 0 .
Default parameters often utilize slow, linear acceleration curves to protect the servo motors. While safe, this inserts unnecessary milliseconds into every tool change and positioning move. Parameters in the 0500 and 0700 series are
Typically, parameter 700 (X), 701 (Z), 702 (3rd), 703 (4th) are used to set the distance from the reference mark to the actual tool position. 3. Adjusting the "Grid Shift" (A "Better" Method)
: Define the stored stroke limits (soft limits). These must be set relative to a correctly established reference position to protect the machine from over-travel. Reference Point Return (Grid Shift) : Used to
Mechanical wear introduces play (backlash) between the ball screw and the nut. FANUC 0T allows you to compensate for this electronically.
