What causes KUKA Robot alarm KRC0381?

Attempting to specify a channel parameter in a command that does not support channels. Incorrect command syntax using legacy channel notation on a non-channel-supporting instruction. Using channel references (e.g., $CHANNEL) with incompatible KRL commands or system functions. Mixing channel-based and non-channel-based command structures in the same program sequence. Outdated program code attempting to use deprecated channel parameters on current KRC firmware version.

How do I fix KUKA Robot alarm KRC0381?

1. Review the command line triggering the alarm in the KRL program and identify any channel parameter specifications 2. Consult the KUKA KRC command reference documentation to verify whether the specific command supports channel parameters 3. Remove or eliminate channel references from the command syntax and use standard parameter notation instead 4. Verify that the KRL program syntax matches the current KRC controller firmware version requirements 5. Check for any user-defined subroutines or function calls that may be incorrectly passing channel parameters to non-compatible commands 6. Clear the alarm and test the corrected program sequence on the controller to confirm proper command execution

Alarm KRC0381

KUKA Robot KRC0381 - CHANNEL NOT ALLOWED IN COMMAND

This alarm indicates that a command issued to the KUKA KRC controller does not support channel parameters, but a channel specification was included in the command syntax. The controller rejects the command because channels are not applicable or allowed for the particular instruction being executed.
