Product Precautions
- Siemens 6DD1681-0CA2 provides the signal interface between a configured control arrangement and the SITOR power section. The installed processor, converter and connection drawings determine the complete application.
Product type: SITOR interface module
Module designation: SE20.2
System context: SIMADYN D converter control
Module designation: SE20.2
System context: SIMADYN D converter control
The 6DD1681-0CA2 identifies the SE20.2 SITOR interface board. The PG26 hardware instructions include it among the associated SITOR-interface components, alongside the specified screened interconnection cables. It is an interface assembly rather than a PG26 processor, so processor frequency, memory capacity and converter power must remain separate from its identification.
In the D7-SYS ITDC and SITOR-cabinet arrangement, SE20.2 connects converter signals to the control interface with electrical isolation. It occupies three SIMADYN D subrack slots and has a rear voltage connection without a backplane-bus coupling. This describes the applicable cabinet integration and does not imply that a processor, subrack or converter is included with the offered module.
For that ITDC arrangement, SE20.2 connector X3 connects to ITDC X7. Connector X1 carries firing pulses toward the cabinet pulse distribution; X2 receives actual-value and monitoring signals. Preserve the specified grounding and shield connections at the interface and cabinet, and verify the installed connector assignments before reconnecting the power section.

-
SITOR cabinet coupling
Connect the configured controller interface and SITOR power section using the matching SE20.2 arrangement. -
Firing-pulse distribution
Preserve the X1 connection to cabinet pulse distribution and its grounding arrangement. -
Converter feedback
Retain the X2 actual-value and monitoring connections against the cabinet drawing. -
Legacy interface service
Identify the installed SE20.2, processor and cabling before replacing the interface board.
Prepare 6DD1681-0CA2 against the installed configuration and applicable Siemens instructions. Plan isolation and the resulting interruption of system operation before replacement.
Isolate the converter
Place the drive in a safe state and isolate the power section and control supplies before handling the interface.
Match the assembly
Check the full 6DD1681-0CA2 and SE20.2 marking against the installed unit.
Preserve connector allocation
Record X1, X2 and X3 wiring and retain the approved cabinet connection diagram.
Maintain shielding
Restore the specified shield and ground terminations at the module and cabinet.
Separate component ratings
Do not apply PG26 or ITDC processor specifications as SE20.2 electrical ratings.
Test before release
Verify pulse, feedback and monitoring paths under the approved commissioning procedure before enabling the converter.
