22.4 List of Warning Codes
Warning name Error detail and cause
Absolute Position Data • Axis type was changed.
Incorrect Warning • Backup data for absolute
position restoration is incorrect.
• Homing has never been
executed after system started.
• Homing was started, but not
completed properly.
• Absolute position erase for
driver was detected.
• Machine homing was started,
but not completed properly.
• 'Absolute position erase' at
driver side was detected.
• 'Polarity(607Eh)' b7:position
polarity of driver object was
changed.
Start during Operation Instruction that cannot start
Warning during operation was executed.
JOG Command Input at "JogForward" and "JogBackward"
Both Directions became TRUE at the same time.
Warning
Speed Limit Value Over The target speed is out of the
Warning range when changing speed/
speed override coefficient.
• "AxisName.Pr.VelocityLimit_Po
sitive"
• "AxisName.Pr.VelocityLimit_Ne
gative"
• "AxesGroupName.Pr.VelocityLi
mit"
Acceleration Time Limit Acceleration time exceeded 8400
Over Warning seconds when changing speed/
acceleration (acceleration/
deceleration time)/speed override
coefficient/acceleration override
coefficient.
Deceleration Time Limit Deceleration time exceeded 8400
Over Warning seconds when changing speed/
deceleration (acceleration/
deceleration time)/speed override
coefficient/acceleration override
coefficient.
Detection Operation at
timing (At warning occurrence
start/
during
control
During The current position is
control restored with the same
content as the
incremental system, and
the homing request turns
TRUE.
During Not start after the
control execution of FB is
interrupted.
At start • [At start] Not start after
During the execution of FB is
control interrupted.
• [During control]
Decelerates and
continues stop/wait
until the other JOG
command becomes
FALSE.
During Continues the operation
control at the previous speed.
During Continues the operation
control at the previous speed/

(acceleration/
deceleration time).
During Continues the operation
control at the previous speed/
acceleration
(acceleration/
deceleration time).
Remedy
Perform the homing.
Start when axis is
StandStill.
Set it so that
"JogForward" and
"JogBackward" do not
become TRUE at the
same time.
Set the target speed
within the followings.

override coefficient/
acceleration override
coefficient so that the
acceleration time will not
exceed 8400 seconds.
Set the speed/
deceleration
(acceleration/
deceleration time)/speed
override coefficient/
acceleration override
coefficient so that the
deceleration time will not
exceed 8400 seconds.
