: Always ensure that changes to parameters like 1860 do not compromise the safety of the machine operator or the integrity of the machine itself.
FANUC, a leading manufacturer of CNC (Computer Numerical Control) systems, utilizes a wide range of parameters to customize and optimize the performance of their machines. One such parameter, often encountered by CNC programmers and machine operators, is parameter 1860. This piece aims to provide an in-depth look at FANUC parameter 1860, its significance, and how it influences CNC machine operations.
When squaring up a machine or aligning a twin-drive axis (like a gantry dual-drive system), Parameter 1860 is used to balance the sides. Step-by-Step Guide to Changing Parameter 1860 fanuc parameter 1860
Absolute encoders maintain position memory even when the machine is powered off, using battery backup. However, situations can cause the encoder to lose synchronization with the machine position. Common causes include:
Here is a comprehensive breakdown of what Parameter 1860 does, how it works with related parameters, and how to troubleshoot it. What is FANUC Parameter 1860? : Always ensure that changes to parameters like
For one terrible second, nothing happened. Then, with a familiar, powerful hum, the C-axis rotated smoothly to its home position and locked with a solid clunk . The tool changer cycled. The spindle warmed up.
When things go wrong with the absolute encoder configuration or backup battery, the FANUC screen will flag specific alarms. 1. Alarm 300 (APC Alarm: Axis Need ZRN) This piece aims to provide an in-depth look
Unlike incremental encoders, which require a "homing" sequence every time you turn on the machine, absolute encoders use this parameter to remember their last known position.
The setting values for Parameter 1860 vary depending on the specific FANUC CNC system and the I/O device being used. Here are some common setting values:
If you need to know the specific parameter settings for your particular machine tool, knowing the , model , and controller type (e.g., FANUC 18i-MB) will help me give you more precise instructions. Series 16i-18i-MODEL B - Parameter Manual.pdf - Drivesul
Parameter 1860 is stored in the CNC’s non-volatile SRAM. If the battery backup fails, you will lose it. Always keep a printed or digital backup of all parameters.
