FUJI SAM6821 – XPF R-Axis Motor (Rotation Axis Motor)

Overview

The FUJI SAM6821 is an AC servo motor designed to drive the R-axis (rotational axis) of the placement head in FUJI XPF series high-speed SMT machines. It enables precise component orientation control by rotating the nozzle or placement unit before mounting.

Key Features

High-precision rotational control for accurate component angle adjustment
Fast response time, ideal for high-speed placement heads
Equipped with a built-in encoder for closed-loop feedback and angle precision
Built for durability in high-duty-cycle SMT production environments
Compact design for integration into placement head assemblies

Application

Used in FUJI XPF series pick-and-place machines:

XPF, XPF-L, XPF-W
Controls the R-axis (rotation) of heads such as H01, H04, H08, H24
Ensures proper orientation of QFPs, connectors, and other angular-sensitive components

Typical Specifications

Benefits

Ensures precise component orientation before placement
Reduces misalignment, rotation error, and placement defects
Works seamlessly with FUJI’s advanced placement algorithms
Designed to integrate directly with FUJI’s control architecture
Improves throughput and placement yield in high-mix environments

FAQ Guide – FUJI SAM6821 XPF R-Axis Motor

General Information

Q1: What is the FUJI SAM6821 motor used for?

A: The SAM6821 is an AC servo motor designed for the R-axis (rotational axis) in FUJI XPF series SMT machines. It rotates the placement nozzle to align components to the correct orientation before placement on the PCB.

Q2: Which machines use the SAM6821 motor?

A: The motor is used in FUJI XPF, XPF-L, and XPF-W placement machines. It is installed in heads such as H01, H04, H08, and H24 that require R-axis (nozzle rotation) control.

Operation and Features

Q3: What does the R-axis control?

A: The R-axis adjusts the rotation angle of the placement nozzle to match the programmed orientation of the component on the PCB.

Q4: Is this motor a closed-loop system?

A: Yes. The SAM6821 includes an internal encoder that provides real-time position feedback to the controller, enabling high-precision closed-loop control of rotation.

Q5: What components work with the SAM6821?

Maintenance & Troubleshooting

Q6: What regular maintenance is required?

Inspect cables (power and encoder) for wear or damage
Ensure motor mounting is secure and aligned
Clean the head area of dust and debris
Check R-axis rotation accuracy during regular calibration

Q7: Common R-axis motor problems and solutions

Best Practices

Always power off the machine before replacing the motor or cables
Use only genuine FUJI parts to ensure compatibility
Perform axis calibration after motor replacement or repair
Maintain a clean operating environment to protect motor integrity
Log and monitor R-axis alarms for trend analysis and preventive maintenance
