Action
Press the data cancellation key and then input correct data.

402 ILLEGAL NUMBER INPUT

Cause
1. The work number of a display inhibiting program was specified.
2. The numeric value that has been input is out of the allowable range.
Action
1. The operation concerned cannot be performed for the program of display inhibition (Program management function).
2. Press the clear key and then input correct data.

403 PROGRAM TOO LARGE

Cause
The limit of 2000 lines per program has been exceeded.
Action
Recreate the program so that it consists of 2000 lines or less.

2. Additional preparation of process control data is no longer possible since 100 sets of such data have already been stored.
3. Additional preparation of program layout data is no longer possible since 4000 sets of such data have already been stored.
Action
Make an available storage area by either erasing an unnecessary machining program from the memory or saving a machining program onto an external storage, and then create a new machining program.

405 PROGRAM No. NOT FOUND

Cause
An attempt has been made to select a program whose work number has not been registered.
Action
Select a program whose work number has been registered.

406 MEMORY PROTECT

Cause
1. Inhibiting operation (editing, erasing, renumber of work number and entry of names) has been performed for the editinhibiting program.
2. PROGRAM LOCK/ENABLE switch on the operating panel is set to the LOCK position.
3. An attempt has been made to carry out "TOOL NAME ORDER" operation on the TOOL DATA display while a tool remains set in the spindle.
Action
1. The operation concerned cannot be performed for the edit-inhibiting program (program management function).
2. Set the PROGRAM LOCK/ENABLE switch to the ENABLE position.
3. Remove the tool from the spindle, and then carry out the operation once again.

Action
1. During tape operation mode, programs cannot be displayed on the EIA MONITOR display.
2. Select a display other than the EIA MONITOR display before changing the operation mode to tape operation mode.

475 NO EIA/ISO OPTION

Cause
An attempt has been made to use an EIA/ISO-option related function in spite of the absence of an EIA/ISO option.
Action
An EIA/ISO-option related function cannot be used since the system has no EIA/ISO option.

476 NO OPTION

Cause
An attempt has been made to use an optional function in spite of the absence of that option.
Action
This function cannot be used since the system does not have the option for the function.

478 MEMORY PROTECT (MEASURING)

Cause
An attempt has been made to copy the coordinates data in WRITE DATA column of the MEASURE display into the designated position, while measurement using the MEASURE display is in progress.
Action
Copy the coordinates data only after the measurement has been completed.

480 CARD NOT READY

Cause
Executing the memory card I/O function in DATA I/O display mode has been attempted when a memory card was not set.
Action
Set a memory card before using the memory card I/O function.
If a memory card has been set, confirm the insertion direction of the memory card and set it again. If the alarm recurs even so, the memory card is likely to be damaged; replace the memory card and re-execute the I/O function.

481 DIRECTORY NOT FOUND

Cause
Input/output operations on a directory not present in the memory card have been attempted during memory card I/O in DATA I/O display mode.

Cause
Checking the program including the units or conditions (such as the case that angle B is set in the index unit of the initialpoint scheme) that do not allow graphics to be drawn in SOLID mode has been attempted in the SOLID mode of the TOOL PATH CHECK display.
Action
Before checking the tool path, cancel the SOLID mode or delete the unit that cannot be drawn in the SOLID mode.

484 INCORRECT SPINDLE TOOL

Cause
The [LENG-OFS TEACH] menu key has been pressed in spite of the fact that a tool not having its "Length Offset Data" item displayed in TOOL DATA display mode (for example, a turning tool) was mounted in the spindle.
Action
Check the tool mounted in the spindle.

485 INCORRECT HEAD INDEX

Cause
Executing the tool nose position storage function (TEACH) has been attempted when the head index angle displayed in TOOL DATA display mode was neither 0 degrees, 90 degrees, nor 180 degrees.
Action
Execute the tool nose position storage function (TEACH) when the head index angle is either 0 degrees, 90 degrees, or 180 degrees.

486 ILLEGAL JAW DATA

Cause
The use of the jaw shape that has been specified for the program results in interference between adjacent jaws as a result of the SOLID mode PATH CHECK.
Action
Review the jaw data or the workpiece-gripping diameter value.

487 LONG BORING BAR ADAPTER EXISTS

Cause
Assigning a tool other than an inside-diameter turning tool to the magazine pocket holding the adapter for the long boring bar has been attempted.
Action
Review the pocket number or the type of tool to be assigned.
