Cause and
correction
Assumed cause Correction Prevention
An instruction for a motion in the
positive direction was executed
when the positive limit input was
ON, or an instruction for a motion
with no direction specification was
executed when the positive limit
input was ON. An axes group
motion control instruction was
executed when the positive limit
input was ON. Execute an error reset and then
perform a recovery operation in
the negative direction. If the error
occurred during an axes group
motion control instruction, disable
the axes group and then perform
the above operation. If this error
occurs again, check the connec-
tion of the positive limit signal, the
logic setting for the positive limit
input, and the execution condi-
tions for the start command, and
correct any mistakes. Check the
logic settings both in the axis
parameters and in the slave set-
tings. Check to make sure there are no
problems with the positive limit sig-
nal connection, the logic setting for
the positive limit input, and the
execute conditions for the instruc-
tion. Check the logic settings both
in the axis parameters and in the
slave settings.
