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:
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
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
