Fanuc: Parameter 1860
Fanuc provides an approximation:
Like 1860, this bit also indicates if the reference position is set. On many modern FANUC controls (like the 0i or 31i series), 1815 is the primary parameter for setting zero, while 1860 may serve as a status bit or be specific to certain older software versions. When to Modify Parameter 1860 You typically only interact with this parameter during a Reference Position Return (Homing) procedure after a battery replacement or encoder swap: Enable Parameter Write: screen, change PARAMETER WRITE Navigate to Parameter: Go to the System parameters and find 1860. Perform Homing: Manually jog the axis to the physical home position. Change the APZ bit for that axis from 0 to 1. fanuc parameter 1860
If Parameter 1860 is set too low, the machine accelerates violently. This puts immense stress on the ballscrews, thrust bearings, and servo motors. Over time, this leads to premature mechanical failure, reversed backlash, and accuracy issues. Fanuc provides an approximation: Like 1860, this bit
In MDI, run M19; G4 X5.0; M19; (repeat orientation). Perform Homing: Manually jog the axis to the
It maintains the mathematical relationship between the mechanical position of the machine and the electronic pulses sent by the encoder. Relation to Parameter 1815 Parameter 1860 works in tandem with Parameter 1815 , which manages the absolute encoder's status: en.industryarena.com APC (1815 bit 5): Indicates if an absolute position coder is being used. APZ (1815 bit 4):
