Press the (Offset/Setting) hard key on the MDI panel. Press the SETTING soft key. Move the cursor to PARAMETER WRITE (PWE). Change the value from 0 to 1 (or select ON ).
To understand Parameter 1860, you must visualize the control hierarchy:
The reference position (Parameter No. 1860/1861) is updated during homing. fanuc parameter 1860
Before modifying any FANUC parameters, you must enable parameter write access:
Immediately reduce 1860 by 30-40%. If the buzz disappears, re-tune from a lower baseline. Press the (Offset/Setting) hard key on the MDI panel
Highlight the axis you wish to change, type the new value, and press the softkey. Step 4: Cycle Power and Clear Alarms
On FANUC 0i, 16i, 18i, 21i, and 30i/31i/32i Series controls, defines the Position Detector Type for each individual axis. Specifically, it tells the CNC control what kind of feedback device (encoder) is mounted to the servomotor or the machine slide. Change the value from 0 to 1 (or select ON )
For specific numerical values (e.g., what the value should be set to for a particular machine), you must refer to the that came with your specific CNC machine tool, as these are tailored to the machine's mechanics.
