FAQ Guide – FUJI SAM6871 XPF Z-Axis Motor
General Information
Q1: What is the FUJI SAM6871 motor used for?
A: The SAM6871 is an AC servo motor used to control the Z-axis (vertical movement) of the placement head in FUJI XPF series SMT machines. It enables precise pick-and-place motions by adjusting the head’s height during component mounting.
Q2: Which FUJI machines use the SAM6871 motor?
A: The SAM6871 is designed for use in the FUJI XPF series, including:
XPF, XPF-L, and XPF-W models
Compatible with H01, H04, H08, or multi-head configurations depending on system
Functionality & Operation
Q3: What does the Z-axis motor control?
A:
Controls the up/down movement of the nozzle or tool unit
Engages during pick-up and placement to lower or raise the head
Coordinates with X/Y motors for smooth, multi-axis component mounting
Q4: How is it controlled?
A:
The SAM6871 motor is driven by a servo driver board (e.g., XK04032), which receives commands from the machine’s main controller and provides closed-loop feedback via the encoder built into the motor.
Maintenance & Troubleshooting
Q5: What routine maintenance is required?
A:
Inspect power and encoder cables regularly (XH01120, XH01270)
Clean motor area of dust and debris
Check for abnormal noise or vibration during operation
Verify Z-axis alignment and stroke limits
Q6: What are signs of motor failure?
Symptom | Possible Cause | Recommended Action |
Motor does not move | Driver board failure or cable disconnection | Check connections; test or replace driver |
Nozzle does not pick/place | Z-axis movement obstructed or misaligned | Inspect ball screw, bracket, or guide shaft |
Z-axis overrun alarm | Faulty limit sensor or encoder error | Test sensors; recalibrate Z-axis encoder |
Excessive vibration or noise | Worn-out motor bearings or misalignment | Replace motor or re-align drive shaft |
