GE DS200LDCCH1AHA Drive Control/LAN Communications Board

Overview

The GE DS200LDCCH1AHA is a Drive Control/LAN Communications board (LDCC) from GE’s DIRECTO-MATIC 2000 family of drives and exciters, which includes the DC2000 and AC2000 drives and the EX2000 exciter. According to GE instruction GEI-100216, the LDCC provides the primary drive and I/O control functions, holds the application software and customer-specific configuration data, controls LAN communications for drive I/O, and includes an onboard operator interface for software adjustments and diagnostic testing.

Seven Star LLC supports industrial and power facilities across Oman and the wider GCC that operate GE DIRECTO-MATIC 2000 drives and EX2000 exciters, including the GE DS200LDCCH1AHA. Identifying the exact part number with all revision letters, together with the drive or exciter model and serial number, helps ensure the correct replacement board is selected ahead of a planned outage.

Operating Principle

The GE DS200LDCCH1AHA belongs to the LDCC board family, which contains four microprocessors: a Drive Control Processor (DCP), a Motor Control Processor (MCP), a Co-motor Processor (CMP) and a LAN Control Processor (LCP). The DCP runs the user interfaces, regulating loops such as speed and position, and system-level functions. The MCP handles inner loops such as current regulators and motor-specific functions, and the CMP supports math-intensive motor control algorithms when the drive needs extra processing. Board self-testing checks these processors and their circuitry.

The LAN Control Processor controls LAN communications and provides both isolated and non-isolated input circuits. The board can process I/O from five bus systems: DLAN+ (GE’s ARCNET-based drive LAN), DLAN, a Genius bus via an interface board such as the DS200ADGI, the CPL serial link and the C-bus, the last two via an interface board such as the DS200ADCI. For local operation, the board has a 16-character display and a KPPL connector for the optional Programmer module, an alphanumeric keypad and display used for software adjustments and diagnostic testing. DN1 bar-graph LEDs show drive fault codes.

Engineering Design of the GE DS200LDCCH1AHA

GE describes the LDCC as connecting to power, customer I/O and the LAN through onboard cable connectors: 1PL to the bridge interface board, 2PL to the signal-level power supply board, 6PL to the terminal board, 3PL to the EX2000 micro-application board in exciter applications, and further connectors for the LAN interface, LAN terminal board, Programmer module and Genius/CPL interface board. The board is held in the drive by plastic snap holders, and Berg-type jumpers set options such as EEPROM write protection (JP1) and the DLAN circuit type.

The LDCC stores configuration data in six flash PROMs, which are programmed at the factory and can be reprogrammed in the field, and field-adjustable parameters in EEPROM U9, which can be moved to a replacement board. GE states that the LDCC has no fuses or other field-serviceable parts and is replaced as a unit. The flash PROM software and the Programmer module are not included when a replacement board is ordered. Before replacement, switch off drive power, use static-sensitive handling and set all jumpers identically to the old board.

Key Features

The GE DS200LDCCH1AHA combines drive control, I/O processing and LAN communications on a single replaceable board. Key features include:

• 16-character onboard display and a KPPL connector for the optional Programmer module (alphanumeric keypad and display) used for software adjustments and diagnostic testing.
• LAN Control Processor handling DLAN+, DLAN, Genius, CPL and C-bus communications, with interface boards as required.
• Four microprocessors (DCP, MCP, CMP and LCP) for drive control, motor control and LAN communications.
• Flash PROM configuration data and field-adjustable EEPROM parameters (U9) that can be transferred to a replacement board.
• DN1 bar-graph LEDs that display drive fault codes, plus onboard testpoints for troubleshooting.
• Hardware and software drive reset options, including automatic internal hardware watchdog protection.
• Cable connectors for the bridge interface, power supply, terminal, meter driver and LAN interface boards.
• Per GE guidelines, can replace the earlier DCC/LCC and SDCC/SLCC board pairs in most drive applications other than AC2000G, PCS2000 and TC2000.

Industrial Applications

The GE DS200LDCCH1AHA is used in GE DIRECTO-MATIC 2000 drive and exciter systems, including DC2000 and AC2000 drives and EX2000 exciters, where the LDCC provides drive and motor control, I/O processing and LAN communications. GEI-100216 notes that the LDCC can replace earlier drive control and LAN control board combinations in many of these applications, which makes correct identification of the installed boards important when planning spares.

Seven Star LLC supports maintenance teams in industrial plants and power facilities in Muscat, Sohar, Salalah and across the GCC that run GE drives and exciters. Confirming the part number and revision letters, the drive or exciter model and the drive serial number before ordering helps avoid mismatches, and planning control board spares ahead of scheduled outages reduces the risk of extended downtime.

Technical Specifications

Key specifications for the GE DS200LDCCH1AHA control board are summarized below.

Drive and Motor Control Functions

GE instruction GEI-100216 describes the LDCC as providing primary drive and I/O control for the DIRECTO-MATIC 2000 family of drives and exciters. The Drive Control Processor runs user interfaces, speed and position loops and system-level functions. The Motor Control Processor handles inner loops such as current regulators together with high-speed and conventional digital I/O, analog I/O, timer/counters and a watchdog timer, while the Co-motor Processor supports math-intensive algorithms when required.

Reset can be generated by the RESET pushbutton, by applying +5 to +24 V dc to connector 6PL pin 30, by software control or by the internal watchdog. GE cautions that the system trips when a hard reset, an interruption of power to the chips, is initiated, so the board should not normally be reset while the drive is running. A soft reset is available through software or the Programmer module and is used to clear faults.

Replacement and Configuration Notes

GE states that the EEPROM (U9), which holds the field-adjustable parameters, can be moved from an old LDCC or SDCC to a new board, and that flash PROMs can be reprogrammed from a PC connected to the drive using the DS206LDCCG1Axx diskette. All jumpers on the replacement board should be set identically to the old board, and in applications with critical analog I/O the gains and offsets may need fine-tuning after replacement.

GEI-100216 covers the DS200LDCCG1A group. The board number DS200LDCCH1AHA carries a different group and revision code, so confirm compatibility with the installed drive or exciter documentation before replacement. All digits of the part number matter when ordering. Treat the board as static sensitive, switch off drive power and allow the capacitors to discharge before touching any circuits.
