Cause and
correction
Assumed cause Correction Prevention
A motion instruction was executed
for an axes group while the
MC_Stop instruction was being
executed for a composition axis. Change the Execute input variable
to the MC_Stop instruction for the
composition axis to FALSE, reset
the error, and then execute the
motion control instruction.
Change the Execute input vari-
ables to the MC_Stop instructions
for all of the composition axes to
FALSE before you execute motion
control instruction.

Operation
If "axis" is given for the source details, operation is
not possible for relevant axis. Relevant axis deceler-
ates to a stop if it is in motion.
If "axes group" is given for the source details, opera-
tion is not possible for relevant axes group. Relevant
axes group decelerates to a stop if it is in motion.

Cause and
correction
Assumed cause Correction Prevention
An axis instruction was executed
when there was already a current
instruction and a buffered instruc-
tion for the same axis. Correct the program so that the
number of executed instructions
does not exceed the buffer limit. Do not execute an axis instruction
when there is already a current
instruction and a buffered instruc-
tion for the same axis.
An axes group instruction was
executed when there was already
eight current instructions and buff-
ered instructions for the same
axis. Do not execute an axes group
instruction when there are already
eight current and buffered instruc-
tions for the same axis.
