IRB6400 M94A
50079: Wrist weaving not possible
Check: Use smaller weaving amplitude or a larger TCP.
50080: Position not compatible
Position cannot be reached with the given robot configuration. Check: Modify the robot
position in the program.
50082: Deceleration limit
Calculation of joint deceleration time exceeds internal limits for this motion. Check: Do
not proceed without removing the causes of the error. See Check. Check deceleration
of external axes. Check noise level on I/O connections. Increase Path resolution, Queue
length. Decrease program speed, and/or increase. AccSet parameters (if below 100%).
50083: Speed lowered by system
The speed has been lowered by the system due to dynamic limitations. Check: Decrease
speed and/or do not use close positions at high speed and/or increase acceleration (if
below 100%).
50085: Too many user frames
For mech_unit %s more than one user frame has been defined. Check: Take away one
user frame or define one more mech_unit.
50086: Singularity calc. error
Too close to wrist singularity with respect to numerical resolution for joint 4 of IRB. Check:
Change destination position a few increments.
50087: Singularity problems
Too close to wrist singularity with respect to numerical resolution for joint 6 of IRB. Check:
Change destination position a few increments.
50088: Restart not possible
It is not possible to restart the path due to a previous error. Check: Move the program start
point and start a new movement.
50089: Lower weaving frequency
The weaving period length or period time is too short. Check: Increase weave length or
increase period time.
