Correct the sequence program; change  the parameter number specified in a  functional instruction to a value that is  within the allowable range.

An out-of-range parameter number  is specified in the TMR, TMRB,  CTR, CTRB, DIFU, or DIFD  

functional instruction.

ER28 NO OPTION(I/O LINK  CHx)

Contact us; specify the I/O Link point count  expansion option for the indicated channel.

The I/O Link point count expansion  option is not specified for CHx.

ER31 NO OPTION  

 (EXTENDED PMC LADDER  INSTRUCTION FUNCTION)

Change the sequence program so that it  specifies the adequate PMC model by  using the programmer.

An attempt was made to execute a  ladder program including an  

extended ladder diagram.  

Alternatively, the model set in the  sequence program does not match  the actual model.

ER32 NO I/O DEVICE

<1> Check whether the power of each I/O  device is on.  

<2> Check whether the power of each I/O  device has been turned on before the  CNC.  

<3> Check cable connections.

None of the I/O devices, such as the  I/O Link, connection unit, and Power  Mate, is connected.

ER33 I/O LINK ERROR  or  

ER33 I/O LINK ERROR (CHn)

Contact us; replace the faulty hardware.

The LSI for the I/O Link is faulty.

ER34 I/O LINK ERROR (xx)  or  

ER34 I/O LINK ERROR (CHn xx)

<1> Check the cable connections to the  devices of group xx. 

<2> Check whether the power of each I/O  device has been turned on before the  CNC.  

<3> Replace any device of group xx in  which the PMC control module is  embedded.

An I/O device communication error  occurred on the slave side of group  xx.

ER35 TOO MUCH OUTPUT  DATA IN GROUP (xx)  

or  

ER35 TOO MUCH OUTPUT  DATA IN GROUP (CHn xx)

Reduce the output data count of group xx.

 The output data count of I/O Link  group xx exceeds the upper limit (33  bytes). The superfluous data is  regarded as invalid.

ER36 TOO MUCH INPUT DATA  IN GROUP (xx)  

or  

ER36 TOO MUCH INPUT DATA  IN GROUP (CHn xx)

Reduce the input data count of group xx.

The input data count of I/O Link  group xx exceeds the upper limit (33  bytes). The superfluous data is  regarded as invalid.

Alarm number

Faulty location/corrective action

Contents

ER37 TOO MUCH SLOT IN  BASE or ER37 TOO MUCH SLOT IN  BASE (CHn)

Correct the slot number to a value of 10 or  less.

The slot number for the I/O Link  exceeds the upper limit (10). The  slot number larger than 11 is  regarded as invalid.

ER38 MAX SETTING OUTPUT  DATA OVER (xx) or  ER38 MAX SETTING OUTPUT  DATA OVER (CHn xx)

Reduce the total amount of output data of  all groups to 128 bytes or less.

The I/O area for the I/O Link is  insufficient.  

(The area allocated to the group xx  and later on the output side is  regarded as invalid.)

ER39 MAX SETTING INPUT  DATA OVER (xx) or  ER39 MAX SETTING INPUT  DATA OVER (CHn xx)

Reduce the total amount of input data of  all groups to 128 bytes or less.

The I/O area for the I/O Link is  insufficient.  

(The area allocated to the group xx  and later on the input side is regarded as invalid.)

ER43 PROGRAM DATA ERROR (PT/NT)

<1> Input the sequence program recompiled by FANUC LADDER-III.  <2> If the error persists even after  inputting the sequence program again, contact FANUC.

The sequence program is invalid.

ER56 TOTAL PROGRAM SIZE  OVER (OPTION)

<1> Contact FANUC and set the ladder  number option again.

The total ladder step option is too  large for a multipath PMC.

ER97 IO LINK FAILURE (CHx  yyGROUP)

If this alarm is issued on a machine that  once operated normally, possible causes  are given below.  

(1) When communication with an I/O unit  in the yy group or later is disabled  - The communication cable between  the (yy-1) group and the yy group is  broken or in poor contact.  - An I/O unit in the yy group or later  is powered off or is not powered on  yet.  

- An I/O unit in the yy group is defective or an I/O unit in the (yy-1)  group is defective.  

(2) When the CNC is powered off and  back on again, an I/O unit remains  powered on.  

- When the CNC is powered off and  back on again, all I/O units must be  powered off once.  

If this alarm is issued when the sequence  program is debugged, any of the following  settings may be incorrect in addition to the  above causes.  

(1) I/O module allocation setting  (2) Setting of the parameter of the I/O  Link allocation data select function  I/O Link channel 2-path allocation setting

This alarm is issued when the  number of I/O units is insufficient.  This alarm is issued when the  number of I/O units set by the I/O  module allocation and I/O Link  allocation select function parameters  does not match the number of I/O  units actually connected to the CNC.  None of the I/O units connected to  the channel on which this alarm was  issued is linked.  

The ladder program runs regardless  of this alarm.

WN02 OPERATE PANEL  ADDRESS  

ERROR

Correct the Series 0 operator's panel  address that is set in the PMC system  parameter.

The Series 0 operator's panel  address that is set in the PMC  system parameter is invalid.

Alarm number

Faulty location/corrective action

Contents

WN03 ABORT  

NC-WINDOW/EXIN

<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.

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.

WN07 LADDER SP  

ERROR(STACK)

Correct the sequence program so that the  subprogram has eight or fewer levels of  nesting.

There are too many levels of nesting  (levels more than 8) for the CALL or  CALLU functional instruction to call  the subprogram.

WN09 SEQUENCE PROGRAM  IS NOT WRITTEN TO FLASH  ROM

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.

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.

WN10 NO OPTION(STEP  SEQUENCE)

<1> Add the step sequence option.  <2> Arrange so that the step sequence  subprogram will not be called.

No step sequence option was found  when the system attempted to  execute a step sequence.

WN11 INCOMPATIBLE  

FUNCTION

Recompile the program using FANUC  LADDER-III or ladder editing package.

A function command does not comply with this PMC.

WN57 OVERRIDE FUNCTION  IS ACTIVE

Disable the override function before  shipment because it is used to debug a  ladder program.

The override function is enabled.

WN58 UNSUPPORTED  

FUNCTION

Correct the program using the internal  ladder editing function.

There is an unsupported function  command. The command was not  processed.

WN59 MESSAGE FILE  

SYMBOL UNDEFINED

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

The multi-language display message  file has a symbol not present in the  ladder program.

WN60 MESSAGE FILE  

SYMBOL INVALID

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

A symbol other than the A address is  defined in the multi-language display  message file.

WN61 MESSAGE FILE  

ADDRESS DUPLICATE

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

An A address is redundantly defined  between symbols and addresses or  between symbols.

WN62 MESSAGE FILE  

NUMBER ERROR

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

Different message numbers are  used for the same A address between the ladder program and the  multi-language display message file.

WN63 MESSAGE FILE IS NOT  WRITTEN TO FLASH ROM

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

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.
