The 1870 function is a software option that allows users to perform complex machining operations, such as simultaneous 5-axis machining, or to enable specific hardware configurations, like a second operator panel. When parameter 1860 is set to a specific value, it activates or deactivates this function, allowing users to customize their CNC system to meet their specific needs.
, the tool holder will bind, score, or jam inside the spindle during an M06 cycle. Instead of moving alignment dogs or brackets, engineers modify Parameter 1860 to seamlessly lift or lower the tool-change height position. 📋 Step-by-Step Guide to Changing Parameter 1860

Parameter 1860 acts as a damper on the acceleration command. When the CNC controller sends a command to move at high speed, it doesn't instantly jump to that speed. Instead, it ramps up the speed over a set time to avoid mechanical shock. 1. Acceleration/Deceleration Type

I walked to the aisle. The crates were stacked high enough to block sightlines. My light revealed nothing but dust and labels. Then I noticed it: a child’s sticker tucked behind one crate, a faded cartoon robot with a missing eye. Not vandalism—accidental, the kind that happens when delivery hands pause and drop their coats. Under the sticker, the floor had a small gouge, like a shallow crescent scored by something sharp. The gouge led to a tiny, mottled smear—old oil, pressed dust, a little black hair.
Parameter 1860 a crucial axis-specific setting used to define the
I called the shop foreman. He arrived, eyebrows like scalpel blades. "Cut power," he said. It was the right call, the industrial reflex. We killed the feed. In the blackout the robot arm hung like a cathedral bell. We opened the access panel and found nothing but solder and metal. The boards were intact. The hairs were nowhere to be found.
Press the OFFSET/SETTING key, locate the SETTING screen, and change PARAMETER WRITE from 0 to 1 . The machine will display a non-critical "P/S 100" alarm indicating parameter write is enabled. The 1870 function is a software option that
When troubleshooting vibrations, noise, or "servo lag" errors (like Error 410 or 420), Parameter 1860 is one of the key parameters to adjust. Increasing the value makes the motion smoother but slower; decreasing it makes the motion faster but potentially jerkier. Setting and Adjusting Parameter 1860
When I pass Unit 7 now, I give the keypad a little tap, the way you tap the shoulder of a teammate. The screen shows PARM 1860, then "Amira—caution template." The arm swings steady. Somewhere, in the margins of code and the spaces between shifts, somebody left kindness encoded as an extra-precise number—and it kept us all a little safer.
A week later, the union rep cornered me. "Found something in the archive," she said, sliding a folder across the table. Inside was a photograph from ten years prior: an apprentice leaning against Unit 7, hair longer, eyes laughing, a sticker much like the one I’d found. The back of the photo bore a date and a name—Amira—plus a sentence in a cramped, looping hand: "Left my lucky sticker and my promise. —A."
The primary function of FANUC parameter 1860 is to define the I/O interface for the PLC, which enables communication between the CNC system and external devices, such as sensors, actuators, and other control systems. This parameter setting determines how the CNC system interacts with these external devices, allowing for customized control and monitoring of the machine. Instead of moving alignment dogs or brackets, engineers
: Parameter 1860 serves as the translation bridge. When the CNC starts up, it reads the communication strings from the APC. It calculates the exact distance from the current physical grid mark to the machine's true coordinate origin.

Parameter 1860 does not work in isolation. Adjusting a machine’s physical home or tracking reference requires a synchronized understanding of several interconnected parameters: Parameter Number Function Name Technical Interdependence with 1860 APC / APZ Configuration
