Fanuc Parameter 1860 [cracked] Full ⚡ Instant
: A common error associated with this parameter is "Alarm 309: Reference Return Impossible," which typically occurs if you attempt to set the reference position (APZ bit in 1815) before the system has properly recognized the encoder data or if there is a mismatch with Parameter 1860. Homing After Battery Swap
In semi-closed loop systems, the CNC counts feedback pulses from the motor encoder to determine position. When returning to a reference point (grid method), the reference counter counts pulses from a grid signal until it reaches the value set in , then generates the reference point.
To maximize the benefits of parameter 1860, follow these best practices:
Upon booting up, the CNC will automatically calculate the new encoder relationship and . fanuc parameter 1860 full
: Sets the grid shift amount to fine-tune the zero position. Parameter 1851 : Controls backlash compensation . Safety Note
The configuration of parameter 1860 involves setting a specific value that determines the level of advanced preview and optimization. The value range for this parameter varies depending on the FANUC control system version and the specific machine model.
When an absolute encoder loses battery power (triggering a 300 APC Alarm or 306 APC Battery Zero ), the control system completely clears its relationship with the machine's reference point. Re-homing the machine via defines a new absolute zero. However, it is rare for an operator to manually jog the axis back to the precise, micrometer-perfect original factory zero. Parameter 1860 accounts for this variance. Step-by-Step Calibration Procedure : A common error associated with this parameter
FANUC controllers utilize two distinct grid-shifting parameters depending on the encoder architecture: Target Hardware Grid Shift (Standard) Incremental encoders or physical deceleration dog homing. Parameter 1860 Grid Shift for Absolute Coder
On many FANUC controls, Parameter 1860 works in conjunction with Parameter 1850 (grid shift) and Parameter 1851 (reference position shift). It determines the range (travel distance) the axis must move to verify that it has correctly reached the machine's reference (home) position after a deceleration signal from the deceleration dog.
On many newer Fanuc controls (0i, 31i, 32i), Parameter 1860 is specifically for the reference position. To maximize the benefits of parameter 1860, follow
: The value may "wrap around" based on the encoder's count limits, which is normal behavior for absolute detectors. Related Reference Parameters
: During a reference position establishment sequence (such as after replacing backup batteries or an encoder), the CNC calculates the offset between the encoder's hardware zero grid and the physical machine reference position.
). If the value is too small, the machine will "nuisance trip" on minor vibrations. If it is too large, the machine might allow dangerous mechanical drift before stopping. 3. Comparison: 1860 vs. 1828 It is common to confuse Parameter 1860 with Parameter 1828.
