KUKA Robot KRC0274 - TOO MANY ASYPTP COMMANDS
This alarm indicates that the robot controller has received an excessive number of asynchronous point-to-point (ASYPTP) motion commands in the command queue, exceeding the system's buffer capacity. The controller cannot process commands faster than they are being sent, causing a backlog that prevents normal program execution and motion operations.

TOO MANY ASYPTP COMMANDS
This alarm indicates that the robot controller has received an excessive number of asynchronous point-to-point (ASYPTP) motion commands in the command queue, exceeding the system's buffer capacity. The controller cannot process commands faster than they are being sent, causing a backlog that prevents normal program execution and motion operations.
Common Causes
- Program or external interface sending PTP commands faster than the robot can execute them
- Insufficient dwell time or synchronization between successive motion commands in the application code
- Network communication overload when using external command interfaces (TCP/IP, EtherCAT)
- Faulty or malfunctioning teach pendant repeatedly sending duplicate movement commands
- Real-time system overload or scheduling conflicts preventing timely command processing
Troubleshooting Steps
- 1Stop the current program execution and clear the command queue by cycling the controller power or using the RESET function
- 2Review the robot program logic to identify rapid successive PTP command sequences and add appropriate Wait or Delay commands between motion instructions
- 3If using external command interfaces, verify communication protocol timing and implement command throttling to match robot execution speed
- 4Check system CPU load and active background processes that may be consuming controller resources; disable non-essential diagnostics or monitoring
- 5Inspect the teach pendant connection for hardware faults or stuck buttons that may be generating spurious commands
- 6Consult the KUKA KRC system logs to identify which program section or interface is generating the excessive commands and adjust the command generation rate accordingly
