0005 NO DATA AFTER ADDRESS NC word(s) address + numerical value not in word format.

This alarm is also generated when a custom macro does not contain a reserved word, or does not conform to the syntax.

0006 ILLEGAL USE OF MINUS SIGN A minus sign (–) was specified at an NC instruction word or

system variable where no minus signal may be specified.

decimal point may be specified, or two decimal points were

specified. 0009 IMPROPER NC-ADDRESS An illegal address was specified, or parameter 1020 is not set. 0010 IMPROPER G-CODE An unusable G code is specified. 0011 FEED ZERO ( COMMAND ) The cutting feedrate instructed by an F code has been set to

This alarm is also generated if the F code instructed for the S

code is set extremely small in a rigid tapping instruction as the

tool cannot cut at the programmed lead. 0015 TOO MANY SIMULTANEOUS AXES A move command was specified for more axes than can be

controlled by simultaneous axis control.

Either divide the number of programmed move axes into two

blocks. 0020 OVER TOLERANCE OF RADIUS An arc was specified for which the difference in the radius at

is spiral. 0021 ILLEGAL PLANE SELECT The plane selection instructions G17 to G19 are in error.

Reprogram so that same 3 basic parallel axes are not

specified simultaneously.

stop command was issued, more than 10 characters were input. The I/O device or printed circuit board was defective.

0090 REFERENCE RETURN

INCOMPLETE

1) The reference position return cannot be performed normally because the reference position return start point is too close to the reference position or the speed is too slow. Separate the start point far enough from the reference position, or specify a sufficiently fast speed for reference position return.

2) An attempt was made to set the zero position for the absolute position detector by return to the reference position when it was impossible to set the zero point.

Rotate the motor manually at least one turn, and set the

zero position of the absolute position detector after turning the CNC and servo amplifier off and then on again.

When a multiaxis amplifier was used in a 2-path system across paths, a servo alarm occurred on an axis belonging to another path. When a 2-path system and multiple servo axes between paths are controlled by a multiaxis amplifier, if a servo alarm occurs on an axis belonging to another path of the same amplifier, the MCC of the amplifier goes down and SV0401 V-READY OFF occurs on an axis belonging to the local path in the same amplifier. Since SV0401 is caused by a servo alarm occurred on an axis in another path, SV0007 is caused together to clearly indicate the fact. The axis belonging to another path in the same amplifier resolves the cause of the servo alarm.

(association with reference position and the counter value of the absolute position detector) is required. Perform the return to the reference position. This alarm may occur with other alarms simultaneously. In this case, other alarms must be handled first.

DS0306 APC ALARM: BATTERY VOLTAGE 0 The battery voltage of the absolute position detector has

dropped to a level at which data can no longer be held. Or, the power was supplied to the Pulsecoder for the first time. If this problem recurs after the power is turned off and then back on, the battery or cable may be defective. Replace the battery with the machine turned on.

<1> Check the ladder program to verify

that it is free from errors, and then restart the ladder program (press the RUN key).

<2> Turn on the power of the CNC again.

Correct the sequence program so that the

subprogram has eight or fewer levels of

nesting.

If you want to use a changed sequence

program again next time you power on the

system, write the sequence program to

flash ROM. If you have made any

unwanted change to the sequence

program by mistake, read the original

sequence program from flash ROM.

<1> Add the step sequence option.

<2> Arrange so that the step sequence

subprogram will not be called. Recompile the program using FANUC LADDER-III or ladder editing package. Disable the override function before shipment because it is used to debug a ladder program. Correct the program using the internal ladder editing function.

Correct the error in the multi-language display message file.

When using the modified multi-language display message file, write the message file into a flash ROM.

The ladder program was stopped while communication was in progress between CNC and PMC. This alarm may cause the WINDR, WINDW, EXIN, and DISPB functional instructions to malfunction. There are too many levels of nesting (levels more than 8) for the CALL or CALLU functional instruction to call the subprogram. You have changed the sequence program using the LADDER DIAGRAM EDITOR screen or DATA I/O screen, but you have not yet written the changed sequence program to flash ROM. If you shut down the system without writing the changed sequence program to flash ROM, the changes you have made will be nowhere next time you turn on the power. No step sequence option was found when the system attempted to execute a step sequence. A function command does not comply with this PMC. The override function is enabled.

There is an unsupported function command. The command was not processed. The multi-language display message file has a symbol not present in the ladder program. A symbol other than the A address is defined in the multi-language display message file. An A address is redundantly defined between symbols and addresses or between symbols. Different message numbers are used for the same A address between the ladder program and the multi-language display message file. Multi-language display message data was modified on the data input/output screen, but the modified multi-language display message data is not written to the flash ROM. The modified multi-language display message data is lost during power-on unless it is written to the flash ROM.

When a serial spindle alarm occurs, the following number is displayed on the CNC.

NOTE

*1 Note that the meanings of the Spindle Amplifier indications differ depending on

which LED, the red or yellow LED, is on. When the red LED is on, the Spindle Amplifier indicates a 2-digit alarm number. When the yellow LED is on, the Spindle Amplifier indicates an error number that designates a sequence problem (for example, when a rotation command is entered with the emergency stop

state not released). See "Error Codes (Serial Spindle)." *2 For serial spindle alarms with a number not listed, refer to the following

The orientation function option parameter is not specified, but ORCM (orientation command) is input.

The output switching control function option parameter is not specified, but low-speed characteristic winding is selected (RCH = 1).
