9.1.2.12Internal 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:

1Connection 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	i002	Number of faulty parameter
	Possible fault causes	i003	Index of faulty parameter
	• “Restore to default value” has never been executed	i004	Faulty parameter value
	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	i002	Address of fault memory location
	Possible fault causes	i003	Faulty value in EEPROM
	• A7001 electronics board is defective	i004	Correct parameter value
	• A7009 backplane wiring assembly is defective
	• Plug-in connection X109 is defective
