Installation & Operation FAQs
Q: When connecting the XSDH to a PC via USB for program download, the software shows "device search timeout". How to fix?
A: This is usually caused by driver conflicts or antivirus software blocking. Uninstall existing USB drivers and download the official configuration tool from Xinje's website. Use original USB cables and try different USB ports. Power-cycle the XSDH and re-search the device.
Q: In high-temperature, high-humidity environments, the XSDH has random I/O signal jitters. How to solve?
A: Use shielded cables for I/O wiring with proper grounding. Separate signal cables from power cables by at least 20cm. Set digital filter parameters to 2-5ms. Ensure proper electrical cabinet ventilation to prevent overheating.
Q: When using EtherCAT with European-brand servos, the system reports "PDO mapping timeout". What to do?
A: Confirm PDO mapping table and object dictionary settings are consistent. Enable required PDO groups in Codesys software. Use Cat 5e or above shielded Ethernet cables. Power-cycle both XSDH and servos after configuration.
Q: Relay outputs get burned out when controlling multiple solenoid valves. Why and how to prevent?
A: For frequent switching (more than 10 times per second), use transistor outputs instead of relay outputs. Add surge suppressors in parallel with each solenoid valve. Avoid overloading relay channels beyond the 2A rated current per channel.
Q: In solar-powered outdoor stations, the XSDH shuts down randomly despite proper voltage. What's the cause?
A: Install a DC power filter and 1000-2200μF electrolytic capacitor at the power input terminal to stabilize voltage. Use thicker power cables to reduce voltage drop. Solar inverters often produce voltage ripples that affect stability.
Q: Modbus TCP data update is slow and sometimes freezes. How to optimize?
A: Ensure XSDH and HMI are on same IP subnet. Set Modbus TCP timeout to 500-1000ms. Reduce number of data registers read/written per cycle. Use a switch instead of hub for network connections. Prioritize Modbus TCP communication bandwidth.
Q: In multi-axis motion control, there's noticeable lag in circular interpolation. Solution?
A: Set EtherCAT cycle time to 1ms or lower. Adjust servo PID parameters appropriately. Use built-in oscilloscope function to monitor motion curves. Fine-tune acceleration/deceleration parameters. Eliminate redundant program logic.
Q: Controller fails to start in cold weather. Is it a hardware defect?
A: No, moisture condensation inside the controller during temperature drops can cause temporary malfunctions. Install a small heater in the electrical cabinet. Seal cabinet properly. Power on for 5 minutes without running program to evaporate internal moisture.
