P460 TAPE I/O ERROR
Details
An error has occurred in the tape reader. Otherwise an error has occurred in the printer during macro
printing.
Remedy
- Check the power and cable of the connected devices.
- Correct the I/O device parameters.
P461 FILE I/O ERROR
Details
- A file of the machining program cannot be read.
Remedy
- In memory mode, the programs stored in memory may have been destroyed. Output all of the
programs and tool data and then format the system.
P480 No spec: Milling
Details
- Polar coordinate interpolation was commanded when the polar coordinate interpolation
specifications were not provided.
Remedy
- Check the specifications.
P481 Illegal G code (mill)
Details
- An illegal G code was used during cylindrical interpolation or polar coordinate interpolation.
- The G07.1 command was issued during the tool radius compensation.
Remedy
- Correct the program.
P482 Illegal axis (mill)
Details
- G07. 1 was commanded when the cylindrical compensation is disabled.
- G12. 1 was commanded when the polar coordinate interpolation is disabled.
- Cylindrical interpolation/polar coordinate interpolation was commanded before tool compensation
cancellation is completed.
Remedy
- Correct the machining program, parameters and PLC interface signals.
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 command unacceptable in the cylindrical interpolation was issued.
- A T command was issued during the cylindrical interpolation or polar coordinate interpolation mode.
- Cylindrical interpolation or polar coordinate interpolation was commanded during the constant
surface speed control mode (G96).
- A plane selection command was issued during the polar coordinate interpolation mode.
- A movement command was issued when the plane was not selected just before or after the G07.1
command.
Remedy
- Correct the program.
