To manage Parameter 1860 successfully:
Parameter 1860 () is a critical servo initialization parameter. It defines the distance the machine axis moves for every single pulse of feedback emitted by the encoder or scale. Essentially, it establishes the mathematical relationship between the electrical pulses detected by the CNC and the physical mechanical travel of the axis. fanuc parameter 1860 full
Technicians often confuse 1860 with other parameters. Here is a clear comparison: To manage Parameter 1860 successfully: Parameter 1860 ()
1860 Parameter Name: Movement pulse (CMR) Data Type: Integer (Valid data range typically 1 to 32767) Technicians often confuse 1860 with other parameters
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.
However, Parameter 1860 specifically interacts with the (Parameter 1821). In standard configurations (using Semi-Closed Loop control with standard encoders), Parameter 1860 is often set to 2 or calculated based on the Gear Ratio.
: When performing a full system backup, Parameter 1860 must be recorded. If these values are lost and not restored correctly, the machine will not know its physical location, potentially leading to overtravel alarms or crashes. Troubleshooting "Full" or Error States
