Continued
50036, Correct regain impossible
Description
A stop occurred with too many close points with corner zones.
At restart the robot will move to a point farther forward in the
program.
Recommended actions
Reduce the number of close points, increase the distance
between them or reduce the speed.
50037, Motors On order ignored
Description
Motors On order ignored since the previous stop was not yet
acknowledged.
Recommended actions
Order Motors On again.
50042, Could not create path
Description
The path could not be created.
Recommended actions
Increase the distance between close points. Decrease speed.
Change acceleration.
50050, Position outside reach
Description
Position for arg joint arg is outside working area.
Joint 1-6 : Number of the axis which causes the error.
Joint 23: Combination of axis 2 and 3 causes the error.
Probable causes
The reason may be that ConfL_Off is used and a movement is
too large, more than 90 degrees for an axis.
Recommended actions
Check work object or working range. Move the joint in joint
coordinates. Check Motion system parameters. Insert
intermediate points on large movements.
50052, Joint speed error
Description
The speed of joint arg is wrong relative the ordered speed due
to error in system or collision.
Recommended actions
Check the tune parameters, external forces on the joint and
hardware. Reduce programmed speed.

50053, Too large revolution counter difference
Description
Too large revolution counter difference for joint arg. The system
has detected too large a difference between the actual
revolution counter value on the serial measurement board and
the value anticipated by the system.
Consequences
The robot is not calibrated and may be jogged manually, but
no automatic operation is possible.
Probable causes
The position of the robot arm may have been changed manually
while the power supply was switched off. The serial
measurement board, resolver or cables may also be faulty.
Recommended actions
Update the revolution counter. Check resolver and cables.
Check the serial measurement board to determine whether it
is faulty. Replace the unit if faulty.
50055, Joint load too high
Description
Actual torque on joint arg too high. Might be caused by incorrect
load data, too high acceleration, high external process forces,
low temperature or hardware error.
Recommended actions
Check load data. Reduce acceleration or speed. Check
hardware.
50056, Joint collision
Description
Actual torque on joint arg is higher than ordered while at low
or zero speed. Might be caused by jam error (the arm has got
stuck) or hardware error.
Recommended actions
Check that arm is not stuck.
Check hardware.
Check for other hardware event logs.
50057, Joint not synchronized
Description
The position of joint arg after power down/failure is too far away
from the position before the power down/failure.
Recommended actions
Make a new update of the revolution counter.
