Fault
No.
Cause as a function of fault value
(r047.001, r949.001 or r949.009 with acknowledged error)
10.1.2.5 Drive faults
NOTICE
The monitoring functions F031, F035, F036, and F037 are deactivated in the delivery state.
They can be activated via parameter P820.
F030 Commutation failure or overcurrent has occurred
(active in operating states of – –, I, II)
Possible error causes
♦ Mains voltage dip in regenerative feedback mode
♦ Current control loop not optimized
Fault value:
1 The blocking voltage time area for the commutating
thyristor pair was too small
2 The current crest curve breaks upwards
3 The maximum current value was higher than 250% of
rated device current
4 A paralleled SIMOREG DC Master has detected a
commutation failure or overcurrent
5 Test command specified for the SIMOREG CCP
F031 Speed controller monitoring
(active in operating states of – –, I, II)
The monitor responds when the difference between the connectors selected in P590 and P591 (factory setting: Setpoint/actual
value difference of speed controller) exceeds the limit set in parameter P388 for longer than the time set in parameter P390.
Possible fault causes
♦ Open control loop
♦ Controller not optimized
♦ P590 or P591 is not correctly parameterized
F032 SIMOREG CCP not ready
(active in operating states of < o4.0)
Fault value:
1 No voltage at U, V, W terminals of SIMOREG CCP
2 Voltage at C-D on CCP does not match voltage at C-D on
SIMOREG DC master
3 Surge absorbing capacitors of SIMOREG CCP have not
reached setpoint voltage
4 Paralleling interface cable is not connected to SIMOREG
CCP assigned to paralleling master
5 No connection between SIMOREG DC master and
SIMOREG CCP via G-SST2 serial interface
6 No connection between parallel SIMOREG CCPs
7 Contents of technical data memory on SIMOREG CCP
(MLFB, rated values, serial number) invalid
11 I2t value of voltage chopper 1 is too high (> 100%)
12 I2t value of voltage chopper 2 is too high (> 50%)
20 Chopper capacitors not completely precharged in time
set with P089
10.1.2.6 External faults
F033 Fault message from free function block FB4
(active in all operating states)
Fault value:
1 the binector wired via parameter U102 Index.001 is in the state log."1"
2 the binector wired via parameter U102 Index.002 is in the state log."1"
3 the binector wired via parameter U102 Index.003 is in the state log."1"
4 the binector wired via parameter U102 Index.004 is in the state log."1"
