Siemens · SINUMERIK 828D
This fault indicates that an issue has occurred at the drive object connected to DRIVE-CLiQ socket X102. The fault value (r0949) specifies the first fault that manifested for this particular drive object, providing a pointer to the specific problem. This general fault suggests a problem within the DRIVE-CLiQ communication or the connected component, potentially leading to loss of control or communication with the associated drive component if not addressed.
Click steps to track your progress.
1. Read and document the detailed fault code from parameter r0949 to pinpoint the exact failure occurring on the X102 device.
2. De-energize the system and visually inspect the DRIVE-CLiQ cable and connectors at X102 for foreign objects, bent pins, or signs of overheating.
3. With a digital multimeter, measure the voltage on the auxiliary power supply lines (e.g., 24VDC) at the drive object connected to X102 terminals.
4. Perform a DRIVE-CLiQ topology scan using the engineering software to confirm if the device connected to X102 is being detected.
5. If an identical, known-good drive object is available, temporarily swap the device connected to X102 to isolate if the fault is with the device or the interface.
6. Restore factory default settings for the DRIVE-CLiQ interface and re-commission the device connected to X102 in the engineering software.
