Communication Error

What does S-0-0011 Bit 12 mean?

A Class 1 Diagnostic indicating a critical failure in the SERCOS communication between the master controller and the DDS 2.1 drive. This error can manifest as various issues like MST/MDT failures, invalid communication phase transitions, or address conflicts, leading to a drive shutdown. The drive decelerates to zero speed and shuts down torque. This condition is reset only after the cause is cleared and the command 'Reset Class 1 Diagnostics' is received via the service channel.

• Break or damage in the SERCOS fiber optic cable or connector between the master and DDS 2.1.
• Incorrect SERCOS ring configuration, including incorrect drive addressing (e.g., two drives with the same address).
• Failure of the SERCOS interface module in the DDS 2.1 drive or the master controller.
• Timing parameter mismatches in the SERCOS configuration (e.g., S-0-0001 Control Unit Cycle Time, S-0-0002 SERCOS Cycle Time).
• Invalid communication phase transitions or a master control word not correctly commanding phase changes.

Click steps to track your progress.

1. 1

   Inspect the SERCOS fiber optic cables and connectors for damage, cleanliness, and secure connections.

2. 2

   Verify the SERCOS ring topology and ensure each DDS 2.1 drive has a unique and correct address.

3. 3

   Check the diagnostic indicators on both the master controller and the DDS 2.1 for specific SERCOS status information.

4. 4

   Review and confirm all SERCOS timing parameters (e.g., S-0-0001, S-0-0002, S-0-0003 Minimum AT Transmit Starting Time) are correctly configured in both the master and slave devices.

5. 5

   Command a 'Reset Class 1 Diagnostics' via the service channel after verifying physical connections and parameters.
