XLH EtherCAT Bus Controller: Card-Type Design & High-Performance Core for Versatile Motion Control
Common Installation Issues
Controller fails to start after powering on at overseas factory
Likely voltage mismatch. Domestic devices are designed for 380V, but many countries use 220V industrial power. Use a 3-phase 220V-to-380V step-up transformer to avoid undervoltage protection or power module damage.
EtherCAT bus devices disconnect intermittently with frequent data packet loss
Keep control cables at least 10cm away from high-power equipment. Ensure all devices share a single star grounding point with the controller's dedicated grounding terminal tightly connected to prevent electromagnetic interference.
Local inspections reject equipment due to certification standards
Confirm device has required regional certifications (CE for EU, UL 508 for US). Prepare certification documents in advance and complete supplementary tests if needed to avoid project delays.
Controller overheats and crashes in tropical environments
Ensure operating temperature stays within 0-55℃ range. Install cooling fans or heat sinks if no air conditioning. Maintain proper ventilation and avoid sealed cabinets. Regular dust cleaning prevents heat dissipation blockage.
Technical Operation Solutions
EtherCAT bus fails to connect with servo drives during commissioning
Verify servo's EtherCAT ID matches XDPPro configuration. Use shielded twisted pair cables with proper grounding. Confirm third-party servos support CoE (CANopen over EtherCAT) protocol.
PLC reports power supply errors despite correct 24VDC voltage
Add stabilized DC power supply to handle voltage fluctuations common in overseas grids. Ensure power cables are sufficiently thick to prevent voltage drop over long runs.
Program downloads but motion control functions don't work
Activate motion control license and input actual axis parameters (acceleration, soft limits). Set correct EtherCAT cycle time (1ms for 16+ axes) to prevent motion lag.
Can't connect to PLC remotely for troubleshooting
Ensure factory firewall allows XDPPro communication port (port 502 for Modbus-TCP). Set up VPN connection for dynamic IP environments. Use industrial Ethernet instead of Wi-Fi for stable remote access.
