46 fault codes documented
Please acknowledge errors on the wire heater unit
The welding wire heater unit has reported an error that needs acknowledgment. The robot controller is waiting for confirmation that the heater error has been addressed.
Check media control!
An error related to media control (e.g., process gas, cooling water, compressed air) has occurred. This issue needs to be resolved before the process can continue.
Error of laser system ---> Resumption of process possible after dialog and forced reset of laser
A general error has occurred within the laser system. Resuming the process requires acknowledging a dialog on the HMI and performing a forced reset of the laser system.
Complete program will be continued without active process. Resumption with active process by executing LASER_INIT command
The system is configured to continue the program without an active laser process following a previous error, as selected in a dialog window. To resume with the active laser, a specific command is required.
Laser error -> Details on console of laser system
A general laser error has occurred, and specific details regarding the fault can be found directly on the laser system's console. This indicates the robot controller has detected a laser issue but defers detailed diagnostics.
Error in user-defined sensor code!
An error has occurred within a user-defined function where the return value is not equal to 0. This indicates a logical issue in the custom sensor processing code, preventing correct operation.
Initialization of user-defined sensor code failed!
An error occurred during the initialization of a user-defined sensor function, resulting in a non-zero return value. This prevents the custom sensor from being properly set up for operation.
Laser allocation denied
The system's request to allocate the laser has been denied. This can happen if the laser is already allocated to a different station, is in manual mode, or if another active error prevents allocation.
Invalid laser command -> LASER INIT command necessary
An invalid laser command was initiated, which is incompatible with the current software package or operating state. A program reset, typically by executing a LASER_INIT command, is generally required to clear this state.
Laser error has occurred
A general laser error has been detected within the system. Depending on the nature of the fault, this may also trigger the specific message 'ErrorAtLaser'.
Standstill monitoring: Laser has not been used for a long time and has just been shut down
The laser has been automatically shut down due to prolonged inactivity, as detected by the standstill monitoring. This is a configurable energy-saving feature based on LSR_LaserStandbyDelay.
Laser still not ready or not assigned
The laser program cannot be started because the laser is not in a ready state or has not been assigned for use. Possible causes include the laser being off, undergoing a reset, or being in manual mode.
Laser is still not in standby mode
The laser system has not reached its standby mode after a command or during power-up. This could be due to a required signal not being generated or detected, or an internal error preventing it from entering standby.
Laser still waiting for allocation
The 'LSR Allocate' instruction has been called by the robot program, but the laser is currently not free. This message indicates a delay while the system waits for the laser to become available from another process or station.
Gas pressure too low. The current program will be aborted. Please check gas !!!
The gas pressure has dropped below a critical minimum threshold, causing the current program to abort immediately. This is a critical issue with the gas supply that requires urgent attention.
Cell or laser safety error. Check safety equipment!
A general safety error has been detected within the robot cell or specific to the laser system. This indicates a breach or malfunction in the safety interlocks or protective devices.
Laser error -> Details on laser console ---> Resumption of program after laser reset
A laser error has occurred, with details available on the laser console. The program can be resumed only after acknowledging the error on the laser console and performing a laser reset from the robot controller.
Laser flags critical error to cell control
A critical error has occurred within the laser periphery, and this error is being flagged to the cell control system (e.g., PLC). Depending on the configuration, this might also indicate a robot-related error affecting the laser.
Laser was switched to manual mode ---> Resumption of process after laser reset
The laser has been manually switched into manual mode directly from its console. This prevents automated operation and requires a laser reset from the robot controller to resume the process.
Robot was stopped by an interpreter stop
The robot interpreter has been stopped by one of several conditions: activation of the STOP key, an EMERGENCY STOP, an operator safety intervention, an operating mode change, or releasing the enabling switch.
Periphery not in a safe state
The laser periphery, including all safety equipment, is not in a safe operating state. This can be caused by open safety gates, triggered emergency stops, or other active safety interlocks.
Laser program was canceled
The active laser program has been canceled. This can occur if the signal LSRO_LsrReset is set during an active program, or if the signal LSRO_LsrStartStatic is reset before LSRO_LsrStopProgram has been set.
Please acknowledge errors on laser console first
There are active errors on the laser console that must be acknowledged directly on the laser system HMI before they can be reset or cleared by the robot controller.
Robot stopped ---> Resumption of the process
The robot has stopped due to an error reaction from the system. The process can be resumed after addressing the cause of the stop and responding to any associated dialog prompts.
No process gas!
The required process gas supply is either off, depleted, or not reaching the laser system at the required pressure. This prevents proper laser operation and affects process quality.
No root gas!
The required root gas supply is either off, depleted, or not reaching the laser system at the necessary flow/pressure. This will negatively impact weld quality, especially for root passes, and may cause program interruption.
Function not implemented!
A call was made to a function that has not been implemented in the system. This indicates an attempt to use a feature that is unavailable or not yet developed.
No feedback of the laser by external control
The LSRI_LsrExternEnabled signal, which indicates external control is enabled, is not being generated. This means the laser is not allowing external control, potentially because it's off, resetting, or in manual mode.
Test commands only possible in operating mode Test1 or Test2!
An attempt was made to execute test commands (e.g., focus pulse) while the system is not in the allowed operating modes (Test1 or Test2). Test commands are restricted to specific modes for safety or operational reasons.
Laser is not available and shutter is closed
The laser is not active or available for operation, and its shutter is confirmed to be in the closed position. This can be caused by a missing or undetected activation signal, or an internal error within the laser controller.
Cold run selected
The program is currently executing without laser power, indicated by the 'Laser off' status key on the HMI. This state is intentionally selected, likely for dry runs, testing, or setup procedures.
Programmed position not reached
The system failed to reach a commanded programmed position. This could be due to a sensor issue or a program logic error preventing target position confirmation.
Insufficient gas pressure! Please check gas equipment.
The gas pressure for the process is insufficient for operation. This indicates a problem with the gas supply equipment (e.g., regulator, tank), potentially leading to process quality issues or safety shutdowns.
Laser program could not be activated: Please check errors on laser console
The laser program failed to activate. This may be due to a required signal not being generated or detected by the laser system, or an internal error in the laser controller.
Invalid parameter list
An error occurred during the execution of a technology-specific instruction due to an invalid parameter list. This indicates a problem with the data format, values, or structure passed to the instruction.
Program was aborted or external error signal active
The robot program has been aborted, or an external error signal is currently active. This indicates an interruption to the program flow due to an unhandled condition or an active external fault input.
Standstill monitoring: Laser was switched off because robot welded for too long at the same position
The laser has been automatically deactivated because the robot remained stationary, welding at the same position for a duration exceeding the configured standstill monitoring time (LSR_Stop_InspectionTime).
Safety circuit open, shutter closed
The safety circuit is open, but the laser shutter is currently closed. This could indicate a problem with the safety circuit itself or a discrepancy between the laser's internal light path settings and the program's requested path.
Laser safety circuit is still open: Ensure laser safety before the robot program is resumed
The laser safety circuit remains open, preventing safe laser operation. This could be due to an actual open safety interlock or a mismatch between the light path settings in the laser and the requested light path configuration.
Sensor cable interrupted!
The connection to a sensor has been interrupted, indicating a physical break or disconnection in the sensor cable. This prevents data transmission from the sensor, leading to a loss of monitoring.
Collision monitoring
The distance sensor has detected a collision or an object too close to the monitored path. This triggers a safety stop to prevent damage to the equipment or workpiece.
Sensor error
A general error has been detected by a sensor or its controller. This indicates a malfunction or an unexpected state within the sensor system, requiring attention.
Use of a reserved sensor type!
An attempt was made to initialize a sensor type within a user-defined function that is designated as reserved by the system. Reserved types cannot be used for custom definitions, leading to initialization failure.
Please acknowledge errors of the wirefeed unit
The wire feed unit has encountered an error that requires acknowledgment. The robot controller is awaiting confirmation that the specific error on the wire feed system has been addressed.
Wire heater error
An error has occurred within the wire heater unit, preventing proper heating of the welding wire. This can affect weld quality and potentially stop the welding process.
Wire or wirefeeder not available
The wire feed system is not in a ready state or is unavailable for operation. This could be due to a physical issue with the wire (e.g., tangle, depletion) or a configuration problem within the robot controller.
