Overview
The FUJI XK05780 is an XS-Axis Interlocking Board, also known as the XS Interlock Board, designed for use in FUJI NXT series SMT machines. It plays a key role in coordinating mechanical and electrical interlock functions along the XS (X-Sub) axis, ensuring safe and synchronized movement of the placement head or table mechanism.
Key Features
Controls interlock signals for XS-axis operation Ensures synchronized motion between mechanical modules Provides position detection, safety signal processing, and system coordination Includes interface for signal input/output, limit switches, and sensors Supports fault detection and interlock fail-safe conditions
Applications
Used in FUJI NXT series machines (check model compatibility: e.g., NXT II, NXT III)
Installed in the control system for the XS-axis motion unit
Coordinates movement between placement heads, feeders, and transport systems
Essential for systems with multi-head, multi-station interconnects

FAQ Guide – FUJI XK05780 XS Axis Interlocking Board
General Information
Q1: What is the FUJI XK05780 XS-Axis Interlock Board?
A:
The XK05780 is a signal control PCB used in FUJI NXT SMT machines. It manages interlock signals for the XS-axis (a sub-axis of the main X-axis), ensuring that motorized movements along this axis are safe, coordinated, and properly Q2: Which FUJI systems use this board?
A:
It is primarily used in FUJI NXT series machines, particularly in configurations where multi-head, multi-module coordination is required. It may be present in NXT II, III, and IV models depending on machine layout.
Functions & Features
Q3: What does the XS Interlock Board control?
A:
Signal interlocking for XS-axis motion systems
Limit switch monitoring for safety stops
Coordination between placement head units and feeder modules
Fault detection and safe-stop triggers for axis overrun or misalignment
Q4: What happens if the interlock board fails?
A:
Failure can cause:
Inability to initialize XS-axis
Safety alarms during startup or homing
Axis movement restriction (machine may enter safe mode)
In this case, the board should be tested and, if needed, replaced.
Installation & Maintenance
Q5: Is it user-serviceable?
A:
Yes, it is modular and designed for field replacement. Make sure to:
Power down the machine
Disconnect signal/power harnesses
Replace with an identical part (XK05780)
Verify axis initialization post-installation
Q6: How do I know if the board is working?
A:
Some units include LED indicators showing status
The main control system will confirm interlock OK during startup
Use diagnostic tools or software to trace signal flow
Q7: Does firmware or software affect this board?
A:
Yes. The board interacts with the main controller and may require firmware compatibility. Use only FUJI-approved versions and always check for required updates if replacing with a newer board.
Troubleshooting
| Symptom | Likely Cause | Suggested Action |
| XS-axis not moving | Interlock not releasing | Check board power and signal cables |
| Axis moves then stops with alarm | Fault detection triggered | Inspect connected limit switches and encoder |
| “Interlock Error” on screen | Board signal failure | Replace XK05780 board |
| Axis limit switch not responding | Cable/connection issue | Check associated harness (e.g., XH01245) |
