Communication Errors With Supplementary Boards; F068 Analog Measuring Channel Faulty (Main Setpoint, Main Actual Value Or Analog Select Input); F069 Mlfb Data Are Faulty; F070 Scb1: Serious Initialization Error - Siemens 6RA70 Series Instructions Manual

Fault
No.
Cause as a function of fault value
(r047.001, r949.001 or r949.009 with acknowledged error)
Fault value:
1 Heatsink temperature > permissible heatsink temperature i002 Measured heatsink temperature (16384 .. 100°C)
2 Heatsink temperature sensor is defective
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:
1 MLFB code number (r070) = MLFB code number (r070)
is illegal
2 MLFB data checksum error
3 Works number checksum error
4 Number of words of MLFB data is incorrect

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
