P450 No spec: Chuck barrier
Details
The chuck barrier on command (G22) was specified although the chuck barrier is out of spec-
ifications.
Remedy
- Check the specifications.
P451 No spec: Stroke chk bef travel
Details
Stroke check before travel (G22/G23) was commanded though it is out of specifications.
Remedy
- Check the specifications.
P452 Limit before travel exists
Details
An illegal command, which places the axis travel start/end point in the prohibited area or
moves the axis through the prohibited area, was detected when Stroke check before travel
(G22) was commanded.
Remedy
- Correct the coordinate values of the axis address commanded in the program.
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.
- IC card has not been inserted.
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.
- Ensure that the external device (including an IC card, etc) that contains the file is mounted.
- Correct the parameter settings for HD operation or IC card operation.
P462 Computer link commu error
Details
A communication error occurred during the BTR operation.
Remedy
- "L01 Computer link error" is displayed simultaneously. Take the remedy corresponding to
the error No.
P480 No spec: Milling
Details
- Milling was commanded though it is out of specifications.
- Polar coordinate interpolation was commanded though it is out of specifications.
Remedy
- Check the specifications.
P481 Illegal G code (mill)
Details
- 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.
Remedy
- Correct the program.
P482 Illegal axis (mill)
Details
- A rotary axis was commanded during the milling mode.
- Milling was executed though an illegal value was set for the milling axis No.
- Cylindrical interpolation or polar coordinate interpolation was commanded during mirror im-
age.
- 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.
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 dur-
ing the milling mode.
- Movement was commanded to an axis that had not completed reference position return dur-
ing cylindrical interpolation or polar coordinate interpolation.
Remedy
- Carry out manual reference position return.
