IV - 136
P484 R-pnt ret incomplete (mill)
Details
- Movement was commanded to an axis that had not completed reference position return during the
milling mode.
- Movement was commanded to an axis that had not completed reference position return during
cylindrical interpolation or polar coordinate interpolation.
Remedy
- Carry out manual reference position return.
P485 Illegal modal (mill)
Details
- 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.
Remedy
- Correct the program.
- Issue G40 or G97 before issuing G12.1.
- Issue a T command before issuing G12.1.
- Issue G40 before issuing G13.1.
- 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
Details
- 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.
Remedy
- Correct the program.
P501 Cross (G110) impossible
Details
Mixed control (cross axis control) command (G110) was issued in the following modes.
- During nose R compensation mode
- During pole coordinate interpolation mode
- During cylindrical interpolation mode
- During balance cut mode
- During fixed cycle machining mode
- During facing turret mirror image
- During constant surface speed control mode
- During hobbing mode
- During axis name switch
Remedy
- Correct the program.
