54410000 hex Impossible
Axis Opera-
tion Speci-
fied when the
Servo is OFF
An operation
instruction was exe-
cuted for an axis for
which the Servo is
OFF.
• An operation instruction was
executed for an axis for which
the Servo is OFF.
• Home was preset with the
MC_Home or
MC_HomeWithParameter
instruction for an axis for which
EtherCAT process data com-
munications are not estab-
lished.
S Same as
above.
54420000 hex Composition
Axis Stopped
Error
A motion instruction
was executed for an
axes group while
the MC_Stop
instruction was
being executed for
a composition axis.
• A motion instruction was exe-
cuted for an axes group while
the MC_Stop instruction was
being executed for a composi-
tion axis.
S Same as
above.
54430000 hex Motion Con-
trol Instruc-
tion Multi-
execution
Buffer Limit
Exceeded
The number of
motion control
instructions that is
buffered for Buff-
ered or Blending
Buffer Modes
exceeded the buf-
fer limit.
• An axis instruction was exe-
cuted when there was already a
current instruction and a buff-
ered instruction for the same
axis.

executed when there was
already eight current instruc-
tions and buffered instructions
for the same axis.
S Same as
above.
54440000 hex Insufficient
Travel Dis-

The specified
motion cannot be
executed for the
deceleration rate or
acceleration rate
that was specified
for multi-execution
or re-execution of a
positioning instruc-
tion.
• Stopping at the target position
was not possible for the speci-
fied acceleration/deceleration
rate for multi-execution or re-
execution of a positioning
instruction when the Accelera-

fault and stop.
S Same as
above.

to accelerate or
decelerate to the
transit velocity.
• There was not sufficient travel
distance to accelerate the cur-

(Synchronous Positioning)
instruction.
S Same as
above.
