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 con-
stant 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 co-
ordinate 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 com-
manded during mirror image for facing tool posts.
- The start command of the cylindrical interpolation or polar coordinate interpolation was is-
sued 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.
P503 Illegal G110 axis
Details
- The commanded axis does not exist.
- The mixed control (cross axis control) (G110) was commanded to the axis for which the
mixed control (cross axis control) is disabled.
- The number of axes included in the mixed control (cross axis control) (G110) command is
exceeding the maximum number of axes per part system.
Remedy
- Correct the program.
P511 Synchronization M code error
Details
- 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. (Synchroni-
zation with the M code is valid only in 1st part system or 2nd part system.)
Remedy
- Correct the program.
P520 Control axis superimposition/Designated axis illegal
Details
An axis which was impossible to superimpose was designated as a master axis or superim-
posing axis.
Remedy
Correct the program.
P521 Illegal synchronization axis
Details
The axis specified as a basic or synchronous axis of synchronization across part systems can-
not be synchronized.
Remedy
- Correct the program.
P530 DEC. POINT ERR
Details
A decimal point was added to the address where the decimal point command is not allowed.
("#1274 ext10/bit0 (Type of address enabling/disabling decimal point command)")
Remedy
Do not add any decimal point to the addresses where the decimal point is not allowed.
