KUKA Robot KRC0633 - <SER_1> block size error
<SER_1> block size error
The serial communication received a data block that exceeds the maximum allowed size for the <SER_1> interface. This indicates a protocol violation or misconfiguration in the serial data transmission between the controller and external device.
Common Causes
- External device sending data packets larger than buffer capacity
- Incorrect baud rate or serial protocol settings causing data corruption
- Damaged or improperly configured serial communication cable
- Serial interface buffer size misconfigured in KRC parameters
Troubleshooting Steps
- 1Check the external device's data transmission settings and reduce packet size if possible
- 2Verify serial communication parameters (baud rate, parity, stop bits) match on both controller and device
- 3Inspect the serial cable for damage and ensure proper connections to the <SER_1> port
- 4Review KRC serial interface buffer configuration in the system parameters and increase if supported
- 5Reset the serial communication interface and perform a test transmission with smaller data blocks
