Remedy
P481
Illegal G code (mill)
• An illegal G code was used during the
milling mode.
• An illegal G code was used during
cylindrical interpolation or polar coordinate
interpolation.
• The G07.1 command was issued during the
tool radius compensation.
• Check the program.
P482
Illegal axis (mill)
• A rotary axis was commanded during the
milling mode.
• Milling was executed even though an illegal
value was set for the milling axis No.
• Cylindrical interpolation or polar coordinate
interpolation was commanded during mirror
image.
• Cylindrical interpolation or polar coordinate
interpolation was commanded before the
tool compensation was completed after the
T command.
• G07.1 was commanded when cylindrical
interpolation was not possible (there is no
rotary axis, or external mirror image is ON).
• An axis other than a cylindrical coordinate
system axis was commanded during
cylindrical interpolation.
• Check the machining program, parameters
and PLC I/F signal.
P484
R-pnt ret incomplete (mill)
• 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.
• Carry out manual reference position return.
