Pallet Wrapper fault
Pallet Wrapper Turntable Not Turning
A pallet wrapper turntable that stalls, runs slowly or won't rotate is usually a drive, motor, chain/belt or sensor fault — the mechanical or electrical system that powers and controls turntable rotation has developed a problem.

What causes this
Typical causes
Drive motor or inverter fault
The drive motor has failed or the inverter controlling it has tripped or developed a fault. An inverter fault code is often displayed on the machine or the inverter itself.
Chain or belt slipping or broken
The drive chain or belt from the motor to the turntable has stretched, jumped a sprocket, or snapped. Common on high-usage machines without regular tensioning.
Turntable bearing or roller failure
The turntable support bearings or load rollers have worn or seized, creating too much resistance for the drive to overcome. Usually accompanied by noise.
Home or speed sensor fault
A position or speed sensor for the turntable is reading incorrectly, causing the control system to command incorrect speeds or stop the rotation cycle.
Before calling an engineer
What to check first
These are the practical checks worth trying before calling out an engineer. If none of these resolve the fault, or if the issue keeps returning, it needs a proper diagnosis.
01
Check for any fault code on the display or inverter
Look for a fault code on the main display and also on the inverter unit itself — it usually has its own display or LEDs. Note any codes before resetting.
02
Check the drive chain or belt visually
With the machine isolated, open the turntable drive cover and inspect the chain or belt. Look for slack, damage, or a broken link. The chain should have minimal free play.
03
Try rotating the turntable manually
With the machine isolated, push the turntable by hand. It should rotate smoothly with moderate resistance. Excessive resistance or grinding indicates a bearing or roller issue.
04
Check for obstructions under the turntable
Look for debris, strap remnants or film build-up underneath the turntable that could be catching or loading the drive. Clear any obstruction before testing.
When to call us
If any of these apply, call now
At this point, continued resets or workarounds are unlikely to resolve the underlying fault. A proper diagnosis is faster and cheaper than repeated call-outs for the same issue.
