: 2-Word / Signed Double Word (depending on system resolution). Below are typical values for Parameter 1860 based

: 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 : A common error associated with this parameter

: In machines without counterweights, a spindle may droop during an E-stop before the brake engages. Parameter 1860 will record this displacement, which can lead to slight discrepancies in homing if not accounted for. Zeroing Procedure

: The value is established after an axis is successfully zeroed using Parameter 1815.4 (APZ)

On FANUC 16i, 18i, 21i, 0i-C, 0i-D, and 0i-F series controls, this parameter tells the CNC software exactly how many position feedback pulses (counts) are generated by the feedback device for every single revolution of the servomotor. The Role of Feedback Counts
