KUKA Robot KRC0192 - INPUT BUFFER OVERFLOW **
This alarm indicates that the input buffer of the KRC controller has exceeded its capacity, meaning more data has been received than can be processed or stored at the current rate. This typically occurs when external devices or communication interfaces are sending commands or data faster than the controller can process them, causing a data overflow condition.

INPUT BUFFER OVERFLOW **
This alarm indicates that the input buffer of the KRC controller has exceeded its capacity, meaning more data has been received than can be processed or stored at the current rate. This typically occurs when external devices or communication interfaces are sending commands or data faster than the controller can process them, causing a data overflow condition.
Common Causes
- Communication interface (serial, Ethernet, or fieldbus) receiving data at a rate exceeding controller processing capability
- Malfunctioning or misconfigured external device sending continuous or excessive data streams without proper handshaking
- Incorrect baud rate or communication protocol settings on serial ports or network interfaces
- Hardware buffer size limitations reached due to sustained high-frequency input from multiple sources simultaneously
- Software configuration issue where input message size or frequency settings are not properly tuned for the application
Troubleshooting Steps
- 1Verify all external communication connections and check for any loose or damaged cables that may be causing signal interference or transmission errors
- 2Review and confirm baud rates, parity settings, and communication protocols match between the KRC controller and all connected external devices
- 3Reduce the frequency or data rate of incoming commands from external devices and implement appropriate flow control or handshaking mechanisms
- 4Check the KRC controller's input buffer configuration in the system parameters and increase buffer size if available, or reduce data transmission rates
- 5Monitor the system using KUKA diagnostic tools to identify which communication interface is causing the overflow and isolate the problematic device
- 6Reset the controller after correcting the communication parameters, and verify normal operation with reduced input data rates before returning to production settings
