Fault Description
No.
Cause as a function of fault value
(r047.001, r949.001 or r949.009 with acknowledged error)
Further information (r047.002 to r047.016)
Fault value: r047 Index 002 to 016:
1 Heatsink temperature > permissible heatsink temperature i002 Measured heatsink temperature (16384 .. 100°C)
2 Heatsink temperature sensor is defective i003 Measured ADC value
3 Converter fan is defective
F068 Analog measuring channel faulty (main setpoint, main actual value or analog select input)
(active in all operating states)
Hardware monitoring of measuring circuits
Possible fault causes
• A7001 module defective
• Measuring circuit saturated (input voltage at terminals 4 and 5 or 6 and 7 higher than approx. 11.3V)
Fault value:
1 Measuring channel for main setpoint / analog select input 1 faulty (terminals 4 and 5)
2 Measuring channel for main actual value faulty (terminals 103 and 104)
3 Measuring channel for analog select input 1 faulty (terminals 6 and 7)
F069 MLFB data are faulty
(active in all operating states)
Possible fault causes
♦ Excessive EMC-related interference is present
(e.g. due to unprotected contactors, unscreened cables, loose shield connections)
♦ A7009 backplane wiring assembly is defective
Fault value: r047 Index 002 to 016:
1 MLFB code number (r070) = MLFB code number (r070)
is illegal
i002 Incorrect MLFB code number
2 MLFB data checksum error -
3 Works number checksum error -
4 Number of words of MLFB data is incorrect -
9.1.2.13 Communication errors with supplementary boards
F070 SCB1: Serious initialization error
(active in all operating states)
SCB1 and SCI cannot power up correctly (see diagnostic parameter n697 for details)
Fault value:
12 No connection to slave 1
22 No connection to slave 2
F073 SCB1: Current below 4mA minimum value at analog input1 of slave 1
(active in all operating states)
The cause of the fault may be a cable break
F074 SCB1: Current below 4mA minimum value at analog input2 of slave 1
(active in all operating states)
The cause of the fault may be a cable break
F075 SCB1: Current below 4mA minimum value at analog input3 of slave 1
(active in all operating states)
The cause of the fault may be a cable break
F076 SCB1: Current below 4mA minimum value at analog input1 of slave 2
(active in all operating states)
The cause of the fault may be a cable break
F077 SCB1: Current below 4mA minimum value at analog input2 of slave 2
(active in all operating states)
The cause of the fault may be a cable break
