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.
