P485
Illegal modal (mill)
• The milling mode was turned ON during
nose R compensation or constant surface
speed control.
• A T command was issued during the milling
mode.
• The mode was switched from milling to
cutting during tool compensation.
• Cylindrical interpolation or polar coordinate
interpolation was commanded during the
constant surface speed control mode (G96).
• The command unacceptable in the
cylindrical interpolation was issued.
• A T command was issued during the
cylindrical interpolation or polar coordinate
interpolation mode.
• A movement command was issued when
the plane was not selected just before or
after the G07.1 command.
• A plane selection command was issued
during the polar coordinate interpolation
mode.
• Cylindrical interpolation or polar coordinate
interpolation was commanded during tool
radius compensation.
• The G16 plane in which the radius value of a
cylinder is 0 was specified.
• A cylindrical interpolation or polar
coordinate interpolation command was
issued during coordinate rotation by
program (G68).
• Check the program.
• Before issuing G12.1, issue G40 or G97.
• Before issuing G12.1, issue a T command.
• Before issuing G13.1, issue G40.
• Specify the radius value of a cylinder other
than 0, or specify the X axis's current value
other than 0 before issuing G12.1/G16.
P486 Milling
error
• The milling command was issued during the
mirror image (when parameter or external
input is turned ON).
• Polar coordinate interpolation, cylindrical
interpolation or milling interpolation was
commanded during mirror image for facing
tool posts.
• The start command of the cylindrical
interpolation or polar coordinate
interpolation was issued during the normal
line control.
• Check the program.
P511
Synchronization M code error
• Two or more synchronization M codes were
commanded in the same block.
• The synchronization M code and "!" code
were commanded in the same block.
• Synchronization with the M code was
commanded in 3rd part system or more.
(Synchronization with the M code is valid
only in 1st part system or 2nd part system.)
• Check the program.
P550
No spec: G06.2(NURBS)
There is no NURBS interpolation option.
• Check the specifications.
