KUKA KRC4 System Software 8.3

This message on the KUKA KRC4 KSS 8.3 system indicates that a specific axis ('{(Axis number)}') has unexpectedly stopped or entered a prolonged standstill condition, typically triggered by the internal standstill monitoring function. This can occur due to external impedance, loss of motion command, or incorrect monitoring sensitivity, particularly when in torque mode.

This KUKA KRC4 KSS 8.3 message signals an issue with the positioning monitoring function for a specific axis ('{(Axis number)}'), indicating that the axis is not accurately reaching or maintaining its target position. This can be caused by mechanical inaccuracies, incorrect monitoring parameters, or external disturbances, and is suppressed in torque mode if regular monitoring is deactivated.

This message, specifically '{$variable} value invalid', indicates that a variable in the KUKA KRC4 KSS 8.3 robot program has been accessed or assigned a value that is invalid. This can occur if the variable is uninitialized, assigned an incompatible data type, or its value falls outside expected operational limits, potentially leading to incorrect program execution or runtime errors.

This message from the KUKA KRC4 KSS 8.3 system indicates that the motor for the specified drive ('{Drive}') is blocked or unable to execute the commanded motion, preventing any further movement. This fault typically arises from a significant mechanical obstruction, excessive load, or a severe issue within the motor or gearbox itself. In torque mode, this message is suppressed if regular monitoring functions are deactivated.

This message indicates that the deviation between the commanded position and the actual position of a specified robot drive ('{Drive}') has exceeded the maximum permissible following error limit in the KUKA KRC4 KSS 8.3 system. This often occurs due to external mechanical resistance, insufficient torque, or incorrect motion monitoring settings, particularly in torque mode.

This condition occurs within the KUKA KRC4 KSS 8.3 CELL.SRC program when the robot controller receives a program number from a higher-level controller that is not recognized or defined in the program's CASE statements. It signifies a mismatch in program indexing expectations between the robot and the external master system.
