Common Installation & Usage Questions
Q1: The controller fails to establish EtherCAT communication with servo drives from other brands. What should I do?
A: First, check if the servo drive supports CoE (CANopen over EtherCAT) protocol. Then, confirm the node address of the drive is not duplicated with other devices on the bus. If it still doesn't work, go to the controller's programming software and import the ESI (EtherCAT Slave Information) file of that specific servo model.
Q2: The controller keeps showing "power supply abnormal" alarms in the workshop, but the power cord is connected properly. Why?
A: This is usually caused by unstable voltage in overseas workshops. The XDQ7 requires DC 24V input, but if the voltage fluctuates beyond 18V-30V, the alarm will pop up. Try adding a DC voltage stabilizer or an uninterruptible power supply (UPS) at the input end.
Q3: The controller works fine in the lab, but it crashes frequently after being installed on the production line with heavy dust and vibration. How to fix this?
A: First, make sure you're using the DIN rail mounting clips that come with the controller. For dusty workshops, install a dust cover on the controller's I/O ports. If the environment is extremely harsh, go for the XDQ7-300-EX model with enhanced anti-interference and dust-proof design.
Q4: Can we program the XDQ7 with software in languages other than English? Will it affect the controller's performance?
A: Yes, the programming software supports multiple languages like Spanish, German, and French. This language switch only changes the interface display; it won't affect the controller's operation speed, communication latency, or program execution at all.
Q5: The controller's analog input can't read the value of the sensor from a local area. Is there a tool to point to the sensor?
A: First, confirm the sensor's output type matches the controller's analog input channel. If the type is correct, use the built-in diagnostic function in the programming software. If the raw value is unstable, add a signal isolator between the sensor and the controller.
Q6: What should we do if the controller fails to pass the local fire safety inspection?
A: Focus on two points: first, make sure the controller has the local certification required by the region. Second, check the wiring of the power supply and signal lines: separate the AC power lines from the DC signal lines to avoid electromagnetic interference.
Q7: The controller's expansion modules can't be recognized after being added on-site. How to troubleshoot?
A: First, turn off the controller's power before installing expansion modules. Then, check if the expansion bus connector is plugged in tightly. After powering on again, go to the software's "Hardware Configuration" and scan for new modules.
