An existing file name is specified as the write destination. FILE NOT FOUND Check the file name or number on the file list screen. The specified file is not found. USB MEMORY IS FULL. Delete any unnecessary files and allocate a required capacity. The USB memory is full. FILE IS READ-ONLY. Specify anot her file or check the file attribute and delete the read-only attribute. The specified file is read-only. USB MEMORY IS NOT FORMATTED Replace the USB memory with another one. The inserted USB memory cannot be recognized. FILE NAME IS INVALID. Correct the file name. An invalid character is found in a file name. DIFFERENCE FOUND File comparison detected a mismatch. THE FILE NUMBER DOES NOT EXIST Check the total number of files on the list screen. The entered file number is not found. The entered number is greater than the total number of files. FILE NUMBER IS RESTRICTED TO "128" Enter a numeric value not greater than 128. A value up to 128 can be entered as the file number. FOLDER CANNOT BE SPECIFIED. <1> The specified number indicates a folder. Enter an appropriate number. <2> No folder can be selected in the file list screen. <1> The specified number indicates a folder. <2> An attempt was made to select a folder in the file list screen. THIS FILE CANNOT BE SPECIFIED. <1> The file name corresponding to the specified file number consists of more than 32 characters. Enter an appropriate number. <2> No file having a file name consisting of more than 32 characters can be selected in the file list screen. <1> The file name corresponding to the specified file number consists of more than 32 characters. <2> An attempt was made to select a file having a file name consisting of more than 32 characters. USB HARDWARE ERROR (xxxxxxxxxx) Replace the USB memory with another one. If this error still occurs after replacement, contact the FANUC service center, and report the displayed message correctly. This error occurs due to a USB hardware failure. An error code is indicated in parentheses. INTERNAL ERROR (xxxxxxxxxx) Contact us, and report the displayed message correctly. This error occurs due to an internal factor. An error code is indicated in parentheses. NOT IN EMG STOP MODE Place the system in the emergency stop state. The system is not in the emergency stop state. INVALID LADDER PROGRAM Check the program. The transfer program is illegal. DIFFERENCE FOUND A file com parison detected a mismatch. FLASH ROM IS LOCKED BY OTHER FUNCTION Wait until the PMC user completes processing, then retry. Another PMC user is using the flash ROM. FLASH ROM HEADER ROM DATA ID IS ILLEGAL This file cannot be read. Check the type of the file. An attempt was made to read a file, but its ROM data ID was illegal. FLASH ROM IS USED BY OTHER FUNCTION This file cannot be read. Check the type of the file. The ROM data ID of the file you attempted to read is invalid. INTERNAL ERROR (xxxxxxxxxx) C ontact the FANUC service center, and report the displayed message correctly. An error due to an internal factor occurred.

SEQUENCE PROGRAM IS IN USE BY ONLINE FUNCTION Wait until On-line function, do finish the using I/O function. In general, both of I/O function and On-line function should not be used at the same time. Can not input/output of sequence program, because On-line function is using sequence program. ERROR OCCURS IN LADDER PROGRAM Check the PMC alarm screen and correct the indicated program error accordingly. Data cannot be output because there is an error in the ladder program. UNKNOWN DATA TYPE Check the file. The PMC type of the input data is unknown. MUST BE IN EMERGENCY STOP Set the NC to the emergency stop state. The NC is not in the emergency stop state when the PMC par ameter is read. PWE MUST BE ON Set PWE to 1 on the NC setting screen. PWE on the NC setting screen is 0 during reading from the PMC parameter. MUST BE IN EDIT MODE Set the NC to the EDIT mode. The NC is not in the EDIT mode during writing to the PMC parameter. THIS FUNCTION IS NOT ALLOWED Release the protection by the programmer protection function or 8-level protection function. Protection is made by the programmer protection function or 8-level protection function. PMC PARAMETER IS LOCKED BY OTHER FUNCTION Retry after terminating the other function that is cu rrently using the PMC parameter. The PMC parameter is currently used by some other function and cannot be referenced by this function. THIS DEVICE IS USED BY OTHER FUNCTION Retry after terminating the other function that is cu rrently using the specified device. The specified device is currently used by some other function and cannot be used by this function. PMC PARAMETER IS PROTECTED BY OTHER FUNCTION Retry after terminating the other function that is cu rrently using the PMC parameter. The PMC parameter is currently used by some other function and cannot be changed by this function. LADDER TYPE UNMATCH Specify a program of a valid ty pe. The specified program is of a different type and cannot be read. TOO LARGE SEQUENCE PROGRAM Check the file. Or, change to a step number option that allows you to set a larger program size. The ladder program is too large to read. SEQUENCE PROGRAM IS USED BY OTHER FUNCTION Retry after terminating the other function that is currently displaying the ladder program. The ladder program is currently used by some other function and cannot be referenced by this function. INVALID I/O CONFIGURATION DATA Read correct I/O configuration file. In valid I/O configuration data was read and any of the following operations was performed: - Writing it to the memory card - Comparing it with a memory card file USB - Writing it to flash ROM -Comparing it with flash ROM TOO LARGE I/O CONFIGURATION DATA Check the I/O configuration file. The I/O configuration file is too large to read. I/O CONFIGURATION DATA IS USED BY OTHER FUNCTION Terminate another function that is using the I/O confi guration data, then execute operation again.
