Product Overview
The DS200LDCCH1ANA is a central control board for compatible GE drive and exciter equipment. Unlike a simple communications card, the LDCC handles multiple layers of the control architecture.
GE’s documentation identifies four processors on the LDCC:
DCP — Drive Control Processor
Handles drive-control processing.
MCP — Motor Control Processor
Provides motor-control processing.
CMP — Co-motor Processor
Provides additional processing where required by the application.
LCP — LAN Control Processor
Controls communications with the drive LAN.
The board therefore plays a substantial role in both drive regulation and communications, and its configuration is closely tied to the host system.

Communications Architecture
The LDCC can process I/O associated with several GE communication buses. GEI-100216 documents:
| Interface / Bus | Function |
|---|---|
| DLAN+ | GE ARCNET-based drive LAN |
| DLAN | GE drive LAN used on smaller drives and earlier larger-drive applications |
| Genius bus | Industrial I/O communications through an interface board |
| CPL | Control Party Line serial interface |
| Programmer interface | Local keypad/programmer connection |
The LDCC provides LAN communications through its LCP, while the other processors are responsible for application-specific drive, motor, and I/O processing.
Hardware Configuration
The exact suffix H1ANA should be retained when sourcing this board. GE’s board-identification convention treats all characters in the catalog number as significant. The LDCC family includes multiple hardware configurations and revisions. GE’s documentation also states that board revisions can contain hardware differences, although GE designed replacement revisions to maintain backward compatibility within the applicable revision structure.
The board includes configurable jumpers. For example, GEI-100216 documents:
- JP22 for enabling the 16 MHz clock input to the MCP during normal operation.
- JP7 for feedback VCO gain selection.
- JP8 for bipolar/absolute-value feedback operation.
- Additional LDCC group-identification circuitry.
This makes the configuration of the removed board important when commissioning a replacement.
Typical Applications
The DS200LDCCH1ANA is associated with GE DIRECTO-MATIC 2000 drive systems and Mark V control equipment. Secondary technical references also associate the LDCC family with GE turbine/excitation applications.
Typical equipment applications include legacy:
- GE AC/DC drive control
- Motor-control systems
- Drive LAN communications
- Excitation-control applications
- Mark V-based industrial and turbine equipment
Replacement Considerations
A replacement DS200LDCCH1ANA should be matched carefully against the installed board.
| Verification Item | Importance |
|---|---|
| Complete part number | Confirms the exact LDCC configuration |
| Board revision | Determines hardware compatibility |
| Artwork revision | Confirms PCB revision |
| U9 EEPROM / configuration | Important for application-specific data |
| DCP/MCP/CMP/LCP configuration | Confirms intended control architecture |
| LAN connections | Must match the existing DLAN/DLAN+ arrangement |
| Genius/CPL interfaces | Important where these buses are used |
| Jumper settings | Can affect clock and feedback operation |
| Programmer/keypad configuration | Confirm if installed |
| Host drive / exciter model | Establishes system compatibility |
GE specifically cautions that boards and connections should not be removed or inserted while the drive is energized and recommends appropriate static-control precautions when handling the board.
Board Revision and Compatibility
The DS200LDCCH1ANA is one specific revision/configuration within the broader DS200LDCC family. Current technical listings identify three revisions for this assembly family and describe the earlier revisions as backward-compatible.
This does not mean every DS200LDCC variant should be treated as an unconditional substitute. The host drive, firmware/application configuration, EEPROM, connectors, and hardware revision should all be checked.
Lifecycle Considerations
The is legacy Mark V hardware. Specialist suppliers continue to list the exact part for replacement and repair, but it belongs to an older GE control architecture rather than a current-generation control platform.
For critical installed systems, an exact spare is generally more useful than an unverified alternative because the LDCC contains application-specific processing and configuration hardware.
Important Specification Note
Some secondary suppliers incorrectly classify as an analog-input board, a generic communications card, or a power-supply/instrumentation board. Those descriptions conflict with the GEI-100216 documentation, which identifies the LDCC as a Drive Control/LAN Communications Board.
I would therefore use “Drive Control/LAN Communications Board” as the primary catalog description and avoid publishing unsupported channel counts, nominal input voltage, or standalone power ratings for this exact part.
