Unlike incremental encoders that require a homing sequence (zero return) every time the machine is powered up, an absolute encoder remembers its position. Parameter 1860 holds this numerical value for each controlled axis. System Correspondence:
It is common for technicians to confuse these two, as they both relate to the absolute positioning system. Parameter 1815 Parameter 1860 Configuration and Status Bits Actual Position Data Common Bits APC (Absolute Pulse Coder), APZ (Absolute Position Zero) Numerical coordinate value Manual Action Often toggled (0 to 1) during home position resets Rarely edited manually; usually reset by a "Zero Return" When Should You Check Parameter 1860? fanuc parameter 1860
This parameter stores the of an axis in relation to the machine’s reference point (home). It is primarily used with absolute encoders (detectors). Unlike incremental encoders that require a homing sequence
This article applies to FANUC Series 0i, 16i, 18i, 21i, 30i, 31i, 32i, and Power Motion i controls. For specific machine tool builder variations, consult your original machine documentation. Parameter 1815 Parameter 1860 Configuration and Status Bits
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):
Are you currently facing a specific code or trying to re-home an axis after a battery change?
