What causes KUKA Robot alarm KRC0615?

Wait time calculated using incorrect unit conversion from seconds to clock cycles. Variable overflow due to mathematical error in computing the wait duration. Direct assignment of an excessively large integer value to the WAIT_SEC time parameter. Loop counter or calculation generating accumulating wait times without bounds checking. Copy-paste error introducing an unintended large numeric value into the WAIT_SEC command.

How do I fix KUKA Robot alarm KRC0615?

1. Review the KRL code line containing the WAIT_SEC command to identify the time value being specified 2. Calculate the maximum allowable wait time in seconds based on the basic clock rate of the KRC4 system 3. If the intended wait is longer than the maximum, split it into multiple WAIT_SEC commands in sequence 4. Verify variable declarations and mathematical expressions that calculate wait times to prevent overflow 5. Use the KRC4 debugger in the smartPAD to step through the code and inspect actual variable values 6. Add runtime validation logic to check wait time values before passing them to WAIT_SEC commands

Alarm KRC0615

KUKA Robot KRC0615 - Value range exceeded

The WAIT_SEC command in the KRL program has specified a wait duration that exceeds the maximum allowable value. The wait time expressed in basic clock rate cycles is greater than 2147483647, which overflows the signed 32-bit integer range. Reduce the wait time or break the operation into smaller intervals.
