Technical Specifications

• Product Type: Drive Control and LAN Communications Board.

• System Series: Mark V Speedtronic and DIRECTO-MATIC 2000.

• Instruction Manual: GEI-100216.

• Processor Architecture: Four dedicated microprocessors including Drive Control Processor, LAN Control Processor, Motor Control Processor, and Co-Motor Processor.

• Input Voltage: Supports a wide DC voltage range; specifies 18.5 to 36 VDC for lower-voltage operational tolerance. Some configurations reference AC input.

• Communication Protocols: Supports DLAN+, DLAN, Genius Bus, CPL serial link, and C-Bus differential bus systems.

• I/O Processing: Capable of interfacing with digital and analog I/O signals from multiple bus systems; requires an additional interface board for Genius, CPL, and C-Bus protocols.

• Diagnostic Interface: Equipped with an attachable alphanumeric keypad for local diagnostics, configuration, and fault code viewing.

• PCB Protection: Conformal coating applied to protect against moisture and contaminants.

• Board Reset: Features a RESET button to clear functional faults and assist with diagnostics.

• Operating Temperature: Designed for industrial ranges, generally -20°C to +55°C or -40°C to +70°C depending on the enclosure and ventilation.

• Physical Dimensions: Standard Eurocard format; weight approximately 1.22–1.36 kg. Dimensions given by various suppliers measure 38 cm x 21.5 cm x 4.5 cm as a representative shipping or packaging size.

Key Functional Features

• Quad-Processor Distributed Architecture: Segregates critical tasks across four independent processors. The Drive Control Processor filters digital and analog I/O, the LAN Control Processor manages network communications, the Motor Control Processor handles initial digital I/O processing, and the Co-Motor Processor provides supplemental processing power when the MCP capacity is exceeded. This prevents single-processor overload and ensures deterministic control.

• Multi-Protocol I/O Communication: Processes I/O signals across five distinct bus systems, providing exceptional flexibility when integrating into existing drive and exciter configurations. For specialized systems like Genius, CPL, or C-Bus, connectivity is established through an auxiliary interface board such as the DS200ADCI.

• Advanced Motor Control and Protection: The MCP software incorporates inner-loop current regulators and technology-specific functions for DC phase control, AC motion control, and general-purpose AC control. This enables precise speed, torque, and position regulation, plus protection against overcurrent and overload conditions.

• Onboard Diagnostic Capabilities: Provides direct user interaction through an attachable keypad, granting field engineers immediate access to system parameters, error logs, and diagnostic tests without requiring a separate programming terminal.

• High-Reliability Hardware Design: Uses robust signal filtration to counter high-noise industrial environments. A dedicated stab connector, COM1, stiffens the common reference to LAN interface boards when operating in electrically noisy conditions.

Application Scenarios

• Gas, Steam, and Wind Turbine Automation: Serves as the core drive controller within Mark V turbine control systems, managing the operation of liquid fuel pumps, fuel gas compressors, and generator excitation systems.

• Heavy Industrial Motor Drives: Installed within DIRECTO-MATIC 2000 cabinets to control large DC and AC motors in steel rolling mills, paper machines, and mining conveyors where coordinated multi-axis motion is required.

• Thermal and Renewable Power Generation: Used in power plants for boiler feed pump drives, cooling water circulation pump drives, and wind turbine pitch and yaw control systems.

• Oil and Gas Process Control: Deployed in remote pipeline compressor stations and pumping stations where reliable, deterministic motor control is required and remote LAN communication enables centralized monitoring.
