LS Electric Function Design:
LS Electric maintains FB libraries for common tasks — motion control paired with LS Electric servos, communication protocol handlers, PID control, and HMI helpers. Third-party library support is more limited than for Siemens or Codesys ecosystems. OEM machine builders serving Korean and SE Asian markets typically maintain private libraries tailored to LS Electric I/O and drive families.
Common Challenges and Solutions:
1. Balancing work content across stations for consistent cycle time
- Solution: HMI Integration addresses this through User-friendly operation.
2. Handling product variants with different operations
- Solution: HMI Integration addresses this through Real-time visualization.
3. Managing parts supply and preventing stock-outs
- Solution: HMI Integration addresses this through Remote monitoring capability.
4. Recovering from faults while maintaining quality
- Solution: HMI Integration addresses this through Alarm management.
Safety Considerations:
- Two-hand start buttons for manual stations
- Light curtain muting for parts entry without stopping
- Safe motion for collaborative robot operations
- Lockout/tagout provisions for maintenance
- Emergency stop zoning for partial line operation
Performance Metrics:
- Task and I/O timing: Record minimum, average, and maximum values under a defined test load
- Accuracy: Define an acceptable tolerance and compare it with calibrated reference measurements
- Throughput: Count completed cycles over a fixed interval and record rejected or incomplete cycles
- Fault response: Measure detection, safe-state, alarm, and recovery behavior for each test case
- Resource use: Record memory, communications load, and diagnostic-buffer behavior
