Probable causes
Communication with the source of External Motion Interface
input, for example a sensor or other device, could not be
deactivated correctly.
Recommended actions
Check for possible other error messages regarding sensor or
communication errors.
50452, External Motion Interface cyclic error
Description
Cyclic execution of External Motion Interface correction arg
failed.
Consequences
The program execution is stopped, and the system goes to
Motors Off state.
Probable causes
Communication with the External Motion Interface input source,
for example a sensor or other device, has failed.
Recommended actions
Check for possible other error messages regarding sensor or
communication errors.
50453, Move not allowed in External Motion
Interface
Description
External Motion Interface correction arg is not setup to allow
RAPID movement instructions or jogging.
Consequences
The program execution is stopped, and the system goes to
Motors Off state.
Probable causes
The application utilizing the External Motion Interface
functionality does not allow RAPID movement instructions or
jogging.
Recommended actions
Make sure no other movements are ordered while External
Motion Interface is active.
50454, External Motion Interface position
supervision
Description
The position is outside the allowed range for External Motion
Interface correction arg, mechanical unit arg joint arg.
Operating manual - Troubleshooting IRC5
3HAC020738-001 Revision: AA
Consequences
The program execution is stopped, and the system goes to
Motors Off state.
Probable causes
The deviation of the position from the path or the latest finepoint
exceeded the maximum allowed value.
Recommended actions
Check the application that is utilizing the External Motion
Interface functionality to increase the maximum allowed position
value, or modify the programmed positions to be closer to the
goal position.
50455, External Motion Interface speed
supervision
Description
The speed was outside the allowed range for External Motion
Interface correction arg, mechanical unit arg joint arg.
Consequences
The program execution is stopped, and the system goes to
Motors Off state.
Probable causes
The speed was outside the allowed range.
Recommended actions
Check the application that is utilizing the External Motion
Interface functionality to increase the maximum allowed speed
value.
50456, Close to singularity while External Motion
Interface active
Description
The robot in External Motion Interface correction arg is too
close to a singularity.
Consequences
The program execution is stopped, and the system goes to
Motors Off state.
Probable causes
The robot is close to a singularity, or too small numerical
tolerance have been specified in the system parameters.
Recommended actions
Avoid moving too close to the singularity.
