Remedy
• Check the specifications.
• Check the specifications.
• Review the program and place the
executable statement and macro statement in
separate blocks.
• Review the program and correct it so that the
macro calls do not exceed the limit imposed
by the specification.
• Review the program.
• Review the program.
• The G67 command is the call cancel
command and so the G66 command must be
designated first before it is issued.
• Refer to the operator messages on the DIAG
screen.
• Refer to the instruction manual issued by the
machine manufacturer.
• Review the program and correct it so the
number of " [ " or " ] " does not exceed five.
• Review the program and correct it so that " [ "
and " ] " parentheses are paired up properly.
• Review the program and correct the formula.
• Review the program and correct it so that the
denominator for division in the formula is not
zero.
• Check the arithmetic formula in the program
and correct it so that the value of the integral
number after calculation does not exceed −
31
2 .
• Check the variable data in the program.
• Review the program.
• Review the program.
