10 Frequently Asked Questions
1.How does belt drive compare to ball screws for 24/7 operation?
Belt drives require less maintenance than ball screws in dusty environments.Expect 10,000+hours at 2m/s average speed.Replace belts when tooth deformation exceeds 0.3mm.
Monitor tension monthly to prevent slippage.
2.Can I achieve micron-level accuracy with this belt system?
Yes,when paired with linear encoders(1μm resolution).Compensate for belt elasticity in controller settings.Thermal stability is±0.01mm/°C.Avoid abrupt temperature changes
during calibration.
3.What motors maximize 3m/s performance?
Select 400W+servos with<3ms settling time.Maintain motor-load inertia ratio below 1:8.Use SCHNEEBERGER's MA-20D adapter for direct coupling.Stepper motors limit top
speed to 1.5m/s.
4.How to synchronize dual modules in gantry systems?
Employ electronic gearing via EtherCAT.Mechanical coupling requires alignment within 0.03mm/m.Use cross roller bearings at drive ends to absorb torsion.
5.Is vertical mounting possible with 20kg payloads?
Yes,with spring counterbalances or pneumatic cylinders.Verify motor continuous torque exceeds 1.8x gravity load.Safety brakes are mandatory for vertical axes.
6.How to reduce vibration at maximum speed?
Balance pulleys to ISO G2.5 standard.Tune servo notch filters above 80Hz.Add dampening material to carriage mounting points.Stiffen support structures to 100 N/μm.
7.What cleaning agents suit food processing environments?
Use NSF H1-approved cleaners only.Avoid alkaline solutions degrading PU belts.Post-cleaning,relubricate with food-grade grease(P/N:FG-20).
8.How to replace belts without disassembly?
Loosen tool-free tensioners and slide belts laterally.Maintain original routing path.Post-replacement tension must hit 150Hz±3Hz.Recalibrate home position.
9.Does STO safety work with third-party PLCs?
Yes,wire dual-channel signals to any safety PLC.Test monthly via simulated power loss.Validation requires 100N static load hold test.
10.How to troubleshoot positioning drift?
Check pulley set screw torque(2.5Nm).Verify encoder cable shielding integrity.Update controller tension compensation parameters quarterly.Inspect guide rails for
contamination.
