9.1.2.12 Internal faults
F062 Fault in parameter memory
(active in all operating states)
Software monitoring of correct functioning of the EEPROM module (non-volatile memory) on the A7009 board.
The EEPROM values contains all data which must be protected in the case of a power failure (i.e. parameter values and process
data which must remain stored during power failures).
The following are monitored:
♦ Connection between the A7001 electronics board and the EEPROM on the A7009 backplane wiring assembly
♦ Whether the parameter values stored on the EEPROM are within the permissible value range
♦ Whether data are being correctly stored on the EEPROM. For this purpose, values are read and checked for correctness
after they are transferred to the module
♦ Whether the checksum of the non-volatile process data in the EEPROM is correct
Possible causes for all fault types:
Excessive EMC-related interference is present (e.g. due to unprotected contactors, unscreened cables, loose shield connections)
Fault value: r047 Index 002 to 016:
1 Connection to EEPROM is faulty
Possible fault causes
• A7001 electronics board is defective
• A7009 backplane wiring assembly is defective
• Plug-in connection X109 is defective
2 Parameter value is outside permissible value range
Possible fault causes
• “Restore to default value” has never been executed
with this software (e.g. after software replacement)
• A7009 backplane wiring assembly is defective
Possible remedy:
• Acknowledge fault, execute “Restore to default value”
and start up the drive again
i002 Number of faulty parameter
i003 Index of faulty parameter
i004 Faulty parameter value
3 Parameter value cannot be stored on EEPROM
Possible fault causes
• A7001 electronics board is defective
• A7009 backplane wiring assembly is defective
• Plug-in connection X109 is defective
i002 Address of fault memory location
i003 Faulty value in EEPROM
i004 Correct parameter value
