Start-Up
Bit 13: Message, "Ud reduced" (H)
An H signal indicates that the DC link voltage has been reduced below the following value:
. 1 35 U
*
The signal changes from H to L when the DC link voltage exceeds the following threshold:
. 1 35 U
*
L signal ("Ud not reduced") is also output for as long as control word 1, Bit 11=0 ("No Ud reduction requested")
is pending and for as long as no Ud reduction command for current-dependent Ud reduction has been
generated internally.
Bit 14: Message, " Motoring mode" (H)
The High signal indicates that the infeed bridge is live or is ready to be made live.
Message, " Generating mode" (L)
The Low signal indicates that the infeed bridge is not live.
Bits 15 to 17: reserved
Bit 18: Message, "Current limit active" (L)
An L signal indicates that the common rectifier is operating at the current limit. If the message is output at a
terminal (CUR, SCB1), an L signal appears there for this message
Bit 19: Signal, "Fault, external 1" (H)
An H signal indicates that a "Fault, external 1" is present in control word bit 15. If this fault is output at a terminal
strip (CUR, SCB1), an L signal appears there for this fault signal.
Bit 20: Signal, "Fault, external 2" (H)
An H signal indicates that a "Fault, external 2" is present in control word bit 26. If this fault is output at a terminal
strip (CUR, SCB1), an L signal appears there for this fault signal.
Bit 21: Signal, "External alarm" (H)
An H signal indicates that an "Alarm, external 1" is present in control word bit 28, or an "alarm, external 2" in
control word, bit 29.
If this fault is output at a terminal strip (CUR, SCB1), an L signal appears there for this fault signal.
Bit 22: Signal, "Alarm I
H signal indicates that the "I
Messages".
If this alarm is output at a terminal strip (CUR, SCB1), an L signal appears there for this fault signal.
Bit 23: Signal "Overtemperature fault signal power section (H)
An H signal indicates that an "Power section temperature too high" fault (F023) is present. Also refer to Section
7 "Fault and Alarm Messages".
If this fault is output at a terminal strip (CUR, SCB1), an L signal appears there for this fault signal.
Bit 24: Signal "Overtemperature alarm power section" (H)
An H signal indicates that the "Power section temperature too high" alarm (A022) is present. Also refer to
Section 7 "Fault and Alarm Messages". If this fault is output at a terminal strip (CUR, SCB1), an L signal
appears there for this fault signal.
Bits 25 to 30: reserved
Bit 31: Signal, "Pre-charging active" (H)
An H signal indicates that the DC link has been charged following a successful ON command.
