[X18:10]
Input of OUTPUT X18-function block
The signal passed to this pointer is outputted at Plug Connector X18:10. It is operative in
all modes.
Based on the connection diagram this interconnection should be done:
- Connect this input to IREF2-POLARITY (13609) at both converters, the Master and
the Follower.

[X18:11]
Input of OUTPUT X18-function block
The signal passed to this pointer is outputted at Plug Connector X18:11. The logic level of
the signal transferred via the cable is inverted compared the one connected to. This
interconnection can be used for a fail-safe circuit. It is operative in all modes.
Based on the connection diagram this interconnection should be done:
- in case a 12 pulse system without redundancy is in use (see INHIB_LOGIC):
- connect this input to RDY_ON (10901) at both converters, the Master and the
Follower
- in case a 12 pulse system with redundancy is in use (see BC-LOGIC):
- connect this input to BC_NOT_ZERO (13621) at both converters, the Master and
the Follower
3613 FB_I: C4 SC:
[X18:12]
Input of OUTPUT X18-function block
The signal passed to this pointer is outputted at Plug Connector X18:12. It is operative in
all modes.
Based on the connection diagram this interconnection should be done:
- in case a 12 pulse system without redundancy is in use (see INHIB_LOGIC):
- connect this input to RUNNING (10903), if this converter is used as a Master
- keep this input unconnected, if this converter is used as a Follower
- in case a 12 pulse system with redundancy is in use (see BC_LOGIC):
- keep this input unconnected at both converters, the Master and the Follower

ADJ_REF1
Parameter of 12-PULSE LOGIC-function block
The current reference exchanged between the two converters via analog data can be
scaled with this parameter. Higher values will increase the reference at that converter this
parameter is set, lower values will reduce the reference. In case the DC current of the two
converters involved is different, this parameter can serve for correction, if the error is
caused by the analog data exchange.
