F03000 NVRAM fault on action
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: A fault occurred during execution of action p7770 = 1, 2 for the NVRAM data.
Fault value (r0949, interpret hexadecimal):
yyxx hex: yy = fault cause, xx = application ID
yy = 1:
The action p7770 = 1 is not supported by this version if Drive Control Chart (DCC) is activated for the drive object
concerned.
yy = 2:
The data length of the specified application is not the same in the NVRAM and the backup.
yy = 3:
The data checksum in p7774 is not correct.
yy = 4:
No data available to load.
Remedy: Perform the remedy according to the results of the troubleshooting.
If necessary, start the action again.
F03001 NVRAM checksum incorrect
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: A checksum error occurred when evaluating the non-volatile data (NVRAM) on the Control Unit.
The NVRAM data affected was deleted.
Remedy: POWER ON all components (switch the power off and then back on again).
F03505 (N, A) CU: Analog input wire breakage
Reaction: OFF1 (NONE, OFF2)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The input current of the analog input has undershot the threshold value parameterized in p0761[0...3].
This fault only occurs when p0756[0...1] = 1 (2 ... 10 V with monitoring) or p0756[0...2] = 3 (4 ... 20 mA with
monitoring) is set.
p0756[0]: Analog input 0
p0756[1]: Analog input 1
p0756[2]: Analog input 2
Fault value (r0949, decimal interpretation):
The component number (p0151) of the component involved is specified at the units, tens and hundreds digit.
The thousands digit specifies the relevant analog input: 0: analog input 0 (AI 0), 1: analog input 1 (AI 1), 2: analog
input 2 (AI 2)
Remedy: Check the connection to the signal source for interruptions.
Check the magnitude of the injected current - it is possible that the infed signal is too low.
The input current measured by the analog input can be read in r0752[x].
A03510 (F, N) CU: Calibration data not plausible
Reaction: NONE
Acknowledge: NONE
Cause: During booting, the calibration data for the analog inputs is read and checked with respect to plausibility.
At least one calibration data point was determined to be invalid.
Remedy: - power down/power up the power supply for the Control Unit.
If it reoccurs, replace the module.
In principle, operation could continue.
The analog channel involved possibly does not achieve the specified accuracy.
