SIMOREG DC-MASTER faults
F030
Commutation fault or an overcurrent condition has occurred - or a test command was issued via U583
(active in all operating states)
Possible error causes
•
Line voltage dip during regenerative operation
•
Current control loop not optimized
Fault value:
1
The blocking voltage-time integral for the commutating
thyristor pair was too small
2
The current cusp breaks upwards
3
The amplitude of the current cusp was higher than 250%
of the actual rated unit current according to r072i002
4
A SIMOREG DC-MASTER connected in parallel has
detected a commutation fault or an overcurrent condition
5
Test command was entered via U583
F032
SIMOREG CCP not ready
(active for operating states < o4.0)
Possible error causes
•
Missing connection or interrupted cable at X172 (G-SST2)
•
For a parallel connection, missing connection or interrupted cable at X165 (parallel interface, master)
•
For a parallel connection, missing connection or interrupted cable at X29_PAR or X30_PAR (turn-off pulse interface)
•
Hardware defect in the charge circuit of the quenching capacitors
•
Ruptured fuse in the armature circuit, either line side or motor side
•
Ruptured fuse in the pre-charging circuit for the chopper capacitors
•
presently in the cooling-down phase necessary for the chopper resistors
•
MLFB data of the SIMOREG CCP (n570, n571, n572) invalid or not available
Fault value:
1
Voltage not available at the connections U, V, W of the
SIMOREG CCP
2
Voltage at C-D at the SIMOREG CCP does not match the
voltage C-D at the SIMOREG DC-MASTER
3
The quenching capacitors of the SIMOREG CCP have
not reached the setpoint voltage
4
The parallel interface cable is not connected at the
SIMOREG CCP, which is assigned the parallel switching
master
5
No connection between the SIMOREG DC-MASTER and
SIMOREG CCP via the serial interface G-SST2
(r799.i001 is not incremented)
6
No connection between parallel SIMOREG CCP units
7
Contents of the memory of the technical data of the
SIMOREG CCP (MLFB, rated values, serial number)
invalid
11
The I2t value (n575) of the voltage limiting chopper 1 is
too high (> 100%)
12
The I2t value (n576) of the voltage limiting chopper 2 is
too high (> 50%)
20
The pre-charging of the chopper capacitors was not able
to be completed within the time set in P089 - or the
condition according to fault value 5 is fulfilled
