Siemens CNC system alarm 230885 maintenance

Siemens 802DSL/828D/840DSL system reports 231885 cyclic data transmission failure

According to the alarm classification rules of Siemens 828D CNC system, alarm number 230885 belongs to hardware faults related to DRIVE CLiQ encoder components

This type of alarm usually indicates a communication problem between the system and the encoder.

Suggested troubleshooting steps

You can follow the following steps for systematic troubleshooting:

Check physical connections

After shutting down, check if the DRIVE CLiQ cable corresponding to the alarm shaft is securely connected to the motor end and servo module end.

Check if the pins inside the cable plug are bent, damaged, or contaminated.

Use the system help function

This is the most direct and effective diagnostic method:

Press the "Alarm" button on the control panel.

Move the cursor to the 230885 alarm code.

Press the 'Help' button, and the system will directly display a detailed explanation of the alarm and recommended handling measures.

Check the hardware of the encoder

If the connection is normal, the problem may lie with the encoder itself. Consider replacing the encoder cable or encoder for testing.

Refer to relevant manuals

Due to the 230885 alarm pointing to the DRIVE CLiQ encoder, it is recommended to further refer to the specific instructions in the 828D Diagnostic Manual regarding the malfunction of this encoder component.

Immediate action suggestion: Use the [Help] function on the machine panel now to view detailed instructions for the 230885 alarm, which can provide you with solutions.
