Closed-loop thyristor current control 5.1.1 Hardware configuration The ITDC converter gating is inserted on a PM5 or PM6 processor and screwed into place. The modules have a local expansion bus (LE bus) via which signals and data are transferred.

However, combinations with other expansion modules is permitted (e.g. IT41) The interface: SE20.2 implements the mechanical conversion and the electrical isolation of the standard SITOR interface from the ITDC to a 6QG5x SITOR cabinet or another drive converter. SITOR sets 6QG2x and 6QG3x differ in the way that the current actual value is sensed, the conditioning of the zero crossover signals and the phase-to-phase voltages. If a 6QG2x or 6QG3x SITOR set is used with an optional field device module (excitation option), then the FB FCS is required. The gating unit has been released for operation with 50 Hz and 60 Hz line supplies (e.g. for PM5); however, it also has automatic frequency adaptation in the range from 10 to 530 Hz.
