Siemens 6RA70 specifications Fault, F063, F064 Watchdog timer has initiated a reset

Fault			Description
No.		Cause as a function of fault value				Further information (r047.002 to r047.016)
		(r047.001, r949.001 or r949.009 with acknowledged error)
		11 Checksum of non-volatile data (part 1)			i002	Calculate checksum
		is not correct			i003 Checksum found in EEPROM
		12 Checksum of non-volatile data (part 2)
		is not correct
		13 Checksum of non-volatile data (part 3)
		is not correct
		20 Checksum of configuring table of parameter values is not
		correct
		Possible fault causes
		• Defective EEPROM
		• “Restore to default value” has never been executed
		with this software (e.g. after software replacement)
		Possible remedy:
		• Acknowledge fault, execute “Restore to default value”
		and start up the drive again! Check interference
		suppression measures and improve if necessary.
F063	Errors in compensation data of analog inputs and outputs
		(active in all operating states)
		This function monitors whether the factory-set compensation data for the analog inputs and outputs are plausible
		Possible fault cause:
		♦ Defective A7001 or A7006 electronics board
		Fault value:		r047 Index 002 to 016:
		11 Incorrect number of words in compensation values			i002 Incorrect number of words
		for analog inputs and outputs of A7001
		12 Checksum error in compensation values for			i002	Calculated checksum
		analog inputs and outputs of A7001			i003	Errored checksum
		13 Incorrect value among compensation values for			i002	Incorrect value
		analog inputs and outputs of A7001
		23 Incorrect value among compensation values for			i002	Incorrect value
		analog inputs and outputs of A7006
F064	Watchdog timer has initiated a reset
		(active in all operating states)
		An internal microprocessor hardware counter monitors whether the program for calculating the firing pulses runs at least once
		every 14 ms (program is executed on average every 2.7 to 3.3 ms). If this is not the case, the counter initiates a reset, F064 is
		then displayed.
		Possible fault causes
		♦ A7001 electronics board is defective
		♦ Excessive EMC-related interference is present (e.g. due to unprotected contactors, unscreened cables, loose shield
		connections)
F065		Illegal microprocessor status
		(active in all operating states)
		An internal microprocessor hardware function monitors the microprocessor for illegal operating states.
		Possible fault causes
		♦ A7001 electronics board is defective
		♦ Excessive EMC-related interference is present (e.g. due to unprotected contactors, unscreened cables, loose shield
		connections)
F067	Converter cooling faulty
	(active in operating states of ≤ o13)
	The heatsink temperature monitoring function is activated 6s after connection of the electronics supply.
	(The current heat sink temperature is indicated at parameter r013 and on connector K050)
