WSC-MD collaborative robots are designed for minimal maintenance requirements. However, regular service is the key to stable operation and long service life. This guide helps operators and service engineers keep the robot running without downtime.
📊 WSC-MD 5-year maintenance cost: $3,500–6,000 — that's 5–8% of the robot's purchase price. For comparison, an industrial robot requires $25,000–50,000 over the same period.
Maintenance Schedule Overview
| Frequency | Work Type | Approximate Time |
|---|---|---|
| Daily | Visual inspection | 5–10 minutes |
| Weekly | Connection check | 20–30 minutes |
| Every 1,000 hours | Lubrication, belt check | 1–2 hours |
| Every 3,000 hours | Consumables, calibration | 3–4 hours |
| Every 10,000 hours | Major overhaul, bearing replacement | 1–2 days |
Daily Inspection (5–10 Minutes)
The operator performs these checks at the start of each shift. Print the checklist and post it near the robot.
- Check for unusual sounds during robot movement
- Verify gripper has no visible damage
- Check lubricant level on guides (visual)
- Verify no oil leaks or condensation
- Confirm pallet and infeed conveyor are securely positioned
- Verify control panel shows no errors
⚠️ If an error appears on the panel: press Stop, photograph the error code, and contact Warsonco support. Do not reset the error and continue operating if you don't know the cause.
Weekly Inspection (20–30 Minutes)
- Cables and connectors: check for chafing, kinks, loose connections. Pay special attention to the gripper cable and motor cables.
- Fasteners: check tightness of robot floor bolts, gripper mounts, and conveyor joints.
- Cleanliness: remove dust and debris from surfaces, especially from ventilation openings and guide rails.
- Test cycle: run 10–20 no-load test cycles, confirm stable motion.
Every 1,000 Hours: Planned Maintenance
Approximately every 3–4 months in single-shift operation, or more frequently in multi-shift production.
Lubrication
WSC-MD collaborative robots use lithium-based grease. Replacement interval: every 3,000 hours or once a year, depending on operating conditions. Recommended lubricant: Kluberplex BEM 41-141 or equivalent.
Belt Inspection
Drive belts (if present in your specific model) should be inspected for cracks, stretching, and proper tension. Replace if defects are found.
Positioning Accuracy Check
Run a test program and measure the deviation of the stacking position from the target. Allowable deviation: ±2 mm. If deviation is greater, recalibration is required.
Common Faults and Troubleshooting
| Symptom | Possible Cause | Solution |
|---|---|---|
| Robot won't start, red indicator lit | Emergency stop activated, power issue | Check emergency stop button, 380V power supply |
| Jerky motion, vibration | Belt loosened, motor issue | Check belt tension, contact support |
| Gripper won't hold load | Worn vacuum cups, low air pressure | Check pressure (6–8 bar), replace vacuum cups |
| Positioning accuracy degraded | Recalibration needed, worn guides | Run calibration procedure (see manual) |
| Robot stops mid-cycle | False sensor trigger, line conflict | Check conveyor sensors, synchronize signals |
| Noise during axis movement | Insufficient lubrication, foreign object | Lubricate guides, inspect for foreign objects |
What's Covered Under Warranty vs Paid Service
| Work / Part | Under Warranty (24 months) | After Warranty |
|---|---|---|
| Remote diagnostics | Free | Free |
| Replacement of failed electronic components | Free | Paid |
| Engineer on-site visit | By arrangement | $200–400/visit |
| Standard consumables (grease, filters) | Customer cost | Customer cost |
| Damage from incorrect operation | Not covered | Paid |
| Software (updates) | Free | Free |
📞 Warsonco Support: remote diagnostics are free. In most cases, an engineer can resolve the issue in 15–30 minutes without a site visit. Save the robot serial number when contacting support.
