Siemens D7-SYS User Manual

Closed-loop thyristor current control

Edition 06.2002
More detailed information about the assignment of the interfaces
specified above is provided in the "Hardware" Manual in the Section "
ITDC expansion module".
A clockwise rotating field with the same phase sequence must be
connected at the power connections and the power supply for the
electronics module -A1. The zero crossovers of voltages V
L12
and V
L13
are retrieved from the power section supply.
The synchronizing voltage is taken from the electronics section at the
secondary of the supply transformer.
If the synchronizing voltage from the SITOR set cannot be used, for
example because the power supply of the SITOR set electronics does not
have the same phase sequence as the power connections, then an
external synchronizing voltage can be entered via connector ITDC-X5:
