Faults / Alarms
Fault
No.
Cause as a function of fault value
(r047.001, r949.001 or r949.009 with acknowledged error)
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:
11 Incorrect number of words in compensation values
for analog inputs and outputs of A7001
12 Checksum error in compensation values for
analog inputs and outputs of A7001
13 Incorrect value among compensation values for
analog inputs and outputs of A7001
23 Incorrect value among compensation values for
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)
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)
