S timeout in stop reaction SS2 %4 ObjId=%5

What does 231-A084 mean?

This error indicates that the maximum permissible time for a controlled stop (SS2 – braking on the contour) for a specific axis group (ObjId) was exceeded. The maximum allowed time for this stop reaction is 30 seconds, implying the braking process took too long or failed to complete within this safety limit.

• The axis group (ObjId) failed to achieve a controlled stop (SS2) within the 30-second time limit.
• Incorrectly configured braking parameters for the axis group.
• Faulty drive or motor components preventing effective braking.
• Error in the SPLC program or PLC program affecting the stop reaction sequence.
• Mechanical issues such as excessive load, friction, or brake wear preventing timely deceleration.

Click steps to track your progress.

1. 1

   Review and optimize the SPLC program and PLC program logic related to the SS2 stop reaction to ensure timely execution.

2. 2

   Check the braking parameters (e.g., deceleration ramps, braking torque limits) for the affected axis group (ObjId) and compare them to the system's mechanical capabilities.

3. 3

   Inspect the drive and motor components, including the motor brake, for proper functionality and wear.

4. 4

   Verify that there are no mechanical obstructions, excessive loads, or binding that would impede the axis group's deceleration.

5. 5

   Measure actual deceleration times to identify if the mechanical system is capable of meeting the required SS2 stop time.
