SIMOREG DC-MASTER Converter Commutation Protector Operating Instructions
7.1.4 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: r047 indices 002 to 016:
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
for i001= 1 to 3 and 5, i002 to i006 are valid
for i001= 4, i002 to i015 are invalid
i002 delay angle (K0100) for a fault situation
i003 EMF actual value (K0287) for a fault situation
i004 Gating unit diagnostics (K0989) for a fault situation
i005 Field current actual value (K0265) for a fault situation
i006 Pulse number (K0105) for a fault situation
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: r047 indices 002 to 016:
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)
for i001= 1 to 12, i002 to i006 are valid
for i001= 20, only i002 is valid
i002 state of the SIMOREG CCP (K0574) for a fault situation
i003 I2t value of chopper 1 (K0575) for a fault situation
i004 I2t value of chopper 2 (K0576) for a fault situation
i005 armature voltage actual value (r038) for a fault situation
in 0.1 V for i005 > 32767 the following applies:
V
ARMATURE
[V] = (65536-r047i005)/10
i006 effective time until a fault is initiated in 20 ms
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
