41309401TH Rev.4 523 /6. List of Error Causes and Corresponding CodesThe table below lists the error causes likely to occur during PC loading and the corresponding codes.When an error occurs, the corresponding error code is displayed, the buzzer sounds in thecorresponding pattern and transition to the permanent loop state occurs. (See Note 1.)See “4. LCD Messages” and “5. Buzzer Sounding Patterns” for the LCD display and buzzer soundupon occurrence of each error.*1. Occurs only in binary format specification.*2. Occurs only in Intel HEX code specification (reservation code not actually used).Note: No error processing (transition to permanent loop state after error code display and buzzersounding in corresponding pattern) occurs when any of the following errors occurs in receivingthe loading program header. The receive data until error occurrence is discarded and theprogram header receiving starts from the beginning again.(1) Header sum check NG(2) Disagreement between loading machine type and machine identifier in header(3) Designation of unspecified parameter in header(4) Designation of other than loading program as data type identifier in header(5) Designation of no succeeding data in descriptor(6) Designation of Intel HEX format as data type(7) 14 seconds timeout in header receiving end waiting stateNo. Error cause1 Timeout of data receiving waiting timer (14 seconds)2 Loading data hash check error3 Flash memory erase/write error4 Disagreement between flash memory and external RAM contents (verify error)5 Header sum check NG *16 Disagreement between loading machine type and machine identifier in header *17 Designation of unspecified parameter in header *18 Extended address record sum check NG *29 Data record sum check NG *210 Start address record sum check NG *211 File end record sum check NG *212 Timeout by failure in normal data receiving for 1 minute in loading waiting state after operation13 RAM check result NG upon starting loading program processingCODE000102030405060708090A0B0C
