Worn/slipping belt or chain (speed drops as load increases)
Pallet Wrapper Runs Slowly or Stalls
If a pallet wrapper runs slower than normal, hesitates, or stalls under load, the cause is typically within the drive system (motor/gearbox/chain/belt), electrical supply/controls, or mechanical resistance on the turntable, arm, or mast carriage. The checks below help you confirm whether it’s a settings limitation, a developing mechanical bind, or a drive/feedback fault that’s reducing torque and speed.
Common things we see on site
Turntable bearing drag (rising resistance causes slow cycles and stalling)
Inverter/drive limiting (faults, derating, or incorrect parameters)
Supply/overload condition (low voltage, overload trips, or motor overheating)
Does This Look Familiar?
Common symptoms when the wrapper runs slow or stalls:
- Turntable/arm slows under load, then recovers (slip or torque limit being hit)
- Machine starts normal, then gradually gets slower (bearing drag or motor overheating/derating)
- Stalls at the same point in rotation (mechanical bind, damaged roller/bearing, or obstruction)
- Carriage struggles on the way up/down (belt/chain slip, worn guides, or mast resistance)
- Intermittent hesitation like “micro-pauses” (safety input bounce, sensor faults, or drive faulting)
Typical Causes Behind This Fault
- Drive belt/chain slipping (loss of drive under load, often worse as it warms up)
- Turntable/arm bearing drag (rollers/bearings dry, worn, or contaminated)
- Motor/gearbox issue (wear, binding, low oil, or developing mechanical failure)
- Inverter/drive limiting (derating, incorrect parameters, or fault history reducing output)
- Electrical supply problems (low voltage, poor connections, phase imbalance on 3-phase)
- Overload/safety inputs stopping motion briefly (guard switch bounce, E-stop circuit issues)
- Excessive mechanical resistance from obstruction, misalignment, or damage in the rotation path
Quick sanity check: If it slows mainly under load, suspect slip/torque limit.
If it slows over time, suspect bearing drag or motor/drive derating.
When It Needs An Engineer
If the wrapper runs noticeably slower than normal or stalls when a load is present, it’s usually quicker to have the drive system and control limits checked properly rather than reducing wrap settings or repeatedly restarting cycles.
!
Drive motors or gearboxes struggling under load
!
Turntable, carriage, or mast components creating excess drag
!
Inverter limits or torque settings restricting movement
!
Mechanical wear or contamination affecting movement
At this stage, structured fault-finding is usually more effective than adjusting speeds or wrap parameters — particularly where motors, gearboxes, or inverters are involved. Slow running or stalling under load often indicates increased resistance or incorrect drive limits that should be addressed before they lead to component failure. Our engineers work across all major pallet wrapper brands and control systems.
