Cause:
A fault occurred during execution of action p7770 = 1 or 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:
Carry out a POWER ON (switch-off/switch-on) for all components.
F03505 (N, A) Analog input wire breakage
Reaction:
OFF1 (NONE, OFF2)
Acknowledge:
IMMEDIATELY (POWER ON)
Cause:
The wire-break monitoring for an analog input has responded.
The input value of the analog input has undershot the threshold value parameterized in p0761[0...3].
p0756[0]: Analog input 0
p0756[1]: Analog input 1
p0756[2]: Analog input 2
Fault value (r0949, interpret decimal):
yxxx dec
y = analog input (0 = analog input 0 (AI 0), 1 = analog input 1 (AI 1), 2 = analog input 2 (AI 2))
xxx = component number (p0151)
Note:
For the following analog input type, the wire breakage monitoring is active:
p0756[0...1] = 1 (2 ... 10 V with monitoring)
p0756[0...2] = 3 (4 ... 20 mA with monitoring)
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.
Note:
The input current measured by the analog input can be read in r0752[x].
A03510 (F, N) 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.
