KUKA Robot KRC0599 - Invalid pulse duration
The alarm is triggered when a pulse duration value specified in a KRL program falls outside the permissible range of 0.05 to 3049 milliseconds. This range limitation ensures proper hardware timing and prevents damage to I/O modules, motor drivers, and connected equipment that rely on valid pulse width specifications.

KUKA Robot KRC0599 - Invalid pulse duration
Invalid pulse duration
The alarm is triggered when a pulse duration value specified in a KRL program falls outside the permissible range of 0.05 to 3049 milliseconds. This range limitation ensures proper hardware timing and prevents damage to I/O modules, motor drivers, and connected equipment that rely on valid pulse width specifications.
Common Causes
- Specifying a pulse duration value less than 0.05 milliseconds, which exceeds hardware switching speed capabilities
- Entering a pulse duration greater than 3049 milliseconds without considering system time constraints
- Using incorrect units or decimal placement in pulse duration calculations within the program logic
- Inheriting invalid pulse values from parameter files or configuration data without validation
- Attempting to generate extremely short or long pulses for specialized I/O operations unsupported by KRC4
Troubleshooting Steps
- 1Verify all pulse duration values in your KRL program are within the valid range of 0.05 to 3049 milliseconds
- 2Check calculations and variable assignments that compute pulse durations to ensure proper unit conversion
- 3Review any imported parameters or configuration files to confirm pulse duration values are valid
- 4Consult hardware specifications for connected devices to ensure the pulse duration is appropriate for the target equipment
- 5Implement validation logic in your program to constrain pulse duration values within acceptable limits
- 6Test with known valid pulse durations first, then gradually adjust to confirm both hardware compatibility and performance
