A very specific question!
Tuning this parameter requires a testing process to ensure the backlash compensation is optimized for your machine's specific friction characteristics. Procedure for Testing: fanuc parameter 1860 full
: If the absolute pulse coder (APC) batteries die, the absolute position is lost. After replacing batteries, you must move the axis to its physical home and toggle Parameter 1815 bit 4 (APZ) to "1". This action updates Parameter 1860 with the new zero-point data. Parameter Backup A very specific question
Parameter 1860 might be too high, forcing the servo to react too aggressively, causing a sudden impact in the backlash-free zone. After replacing batteries, you must move the axis
If you are getting a Stop Excess Error and your Parameter 1860 is set to a standard value, the problem is likely mechanical or electrical, not the parameter itself:
Must be set to use specialized backlash compensation. Parameter 1851: Backlash compensation amount (low speed). Parameter 1852: Backlash compensation amount (high speed).
