Appendix 2. Program Error
Error No.
P60 OVER CMP. LENG.
The commanded movement distance is
too long. (2
P62 F-CMD NOTHING
No feedrate command has been issued.
P70 ARC ERROR
There is an error in the arc start and end
points as well as in the arc center.
P71 ARC CENTER
The arc center is not sought during
R-specified circular interpolation.
P72 NO HELICAL SPC
A helical command has been issued though
it is not included in the specifications.
P90 NO THREAD SPEC
A thread cutting command has been issued
though it is not included in the
specifications.
P93 SCREW PITCH ERR
The screw pitch has not been set correctly
when the thread cutting command is
issued.
P111 PLANE CHG (CR)
A plane selection command (G17, G18, G19)
was issued during the coordinate rotation
command (G68).
P112 PLANE CHG (CC)
• A plane selection command (G17, G18,
G19) has been issued when the tool
radius compensation command (G41,
G42) or nose radius compensation
command (G41, G42, G46) is issued.
• After nose R compensation was
completed, there was no axis movement
command after G40, and the plane
selection command was issued before
the compensation was canceled.
P113 ILLEGAL PLANE
The arc command axis is not on the
selected plane.

was exceeded.)
• Review the axis address command range.
• The default movement modal command at
power on is G01.
This causes the machine to move without a
G01 command if a movement command is
issued in the program, and an alarm results.
Use an F command to specify the feedrate.
• Specify F with a thread lead command.
• Check the numerical values of the addresses
that specify the start and end points as well as
the arc center in the program.
• Check the "+" and "−" directions of the
address numerical values.
• Check the numerical values of the addresses
in the program.
• Check the helical specifications.
• An Axis 3 command was issued in the circular
interpolation command.
• If the command is not a helical command, the
linear command axis will be moved to the
next block.
• Check the specifications.
• Issue the thread cutting command and then
set the screw pitch command properly.
• After the G68 command, always command
G69 (coordinate rotation cancel), and then
issue the plane selection command.
• Issue the plane selection command after
completing the tool radius compensation and
nose R compensation commands (issue the
axis movement command after issuing the
G40 cancel command).
• Issue arc command on the correctly selected
plane.
