These features include address decoding for chip selections, wait-state generators, an interrupt controller, timers/counters, and a direct memory access (DMA) controller.
• The DCP software is responsible for managing user interfaces, external regulating loops (such as speed and location control), and system-level operations.

Motor Control Processor (MCP)

• The Motor Control Processor (MCP) is based on an 80C196 microcontroller (U21) that offers high-speed I/O, traditional digital I/O, analog I/O, timer/counters, and a watchdog timer.
• The MCP handles inner loops such as current regulators and performs technology- and motor-specific operations including dc phase control, ac motion control, and ac general purpose tasks.
• The MCP software is specifically designed to handle these math-intensive functions and ensure efficient and precise motor control.

Co-Motor Processor (CMP)

• For motor control algorithms that are too complex for the MCP, the system employs a TMS320C25 digital signal processor (U35) known as the Co-Motor Processor (CMP). The CMP is utilized only when the drive requires additional processing power. It interfaces with dual-ported RAM and EPROM, and its main purpose is to handle sophisticated motor control algorithms. The CMP is particularly useful in situations where advanced control techniques or demanding motor control applications are involved.
• The control card contains five memory chips that house the onboard software. These include four EPROMs (U11, U12, U22, and U23) which hold pre-configured data encoded at the factory, and one EEPROM (U9) that stores field-adjustable parameters. These memory chips are securely housed in sockets, ensuring easy access and maintenance when necessary.

Card Connections

The Card Connections of the component are essential for establishing communication and connectivity with other boards within the controller system, as well as external signals. These connections are made through eight designated connectors, denoted as "_PL." Each connector serves a specific purpose and facilitates the exchange of information and signals between different components. Here are the details of the card connections:

• 1PL: This connector enables input and output (I/O) communication between the Power Supply/Interface Board (IMCP, DCI, SDCI, or DCFB) and the SDCC (System Display and Control Card). It allows for the transfer of data and control signals between these two boards.
• 2PL: The 2PL connector is responsible for connecting various ±5V, 15V, and 24V direct current (dc) inputs from the Power Supply/Interface Board to the component. These inputs provide the necessary power supply voltages to the component for its operation.
• 3PL: This connector facilitates the transmission of SDCC outputs to the LAN Communications Card (SLCC). It allows for communication between the SDCC and the LAN Communications Card, enabling network connectivity and data exchange.
• 6PL: The 6PL connector serves as an I/O interface between the Drive Terminal Board (NTB) or Simple Drive Terminal Board and the SDCC. It enables the exchange of control signals, feedback, and other relevant information between these components.
• 7PL: This connector establishes I/O communication between the Signal Processor Card (SPC) or Multibridge Signal Processing Card and the component. It enables data transfer and signal processing between the component and these signal processing boards.
• 8PL: Similar to the 6PL connector, the 8PL connector also facilitates I/O communication between the Drive Terminal Board (NTB) or Simple Drive Terminal Board and the SDCC. It provides an additional interface for data exchange and control signals.
• 9PL: The 9PL connector is labeled as "Not Used," indicating that it does not have a designated function or connection in this configuration or context.

Wire jumpers, denoted by the abbreviation WJ, are physical wires used to create connections between different points on the module. They serve similar purposes to hardware jumpers but provide more flexibility in terms of positioning and length. Wire jumpers are typically used for specific configuration needs or customizations, allowing users to establish specific connections or bypass certain circuitry as required.
• Both hardware jumpers and wire jumpers contribute to the module's configurability by providing options for factory testing and user-defined settings. While some jumper configurations may be pre-programmed by the manufacturer to cater to common use cases, the hardware's flexibility allows for modifications and adjustments to suit individual requirements. The factory-set positions of the jumpers are documented on the test data sheets accompanying each controller, typically found in the drive/exciter door pocket. These sheets provide important information for identifying the correct jumper configurations based on the specific controller model.

Operator-Maintenance Interface

• An IBM-compatible PC, color monitor, keyboard, cursor positioning device (either touch screen and/or trackball or mouse), and printer serve as the system's primary operator interface. The operator interface is used to issue commands such as start/stop, load/unload, manage and log alarms, and monitor unit operation. The operator interface does not control or protect the unit, with the exception of the Plant Load Control option. ARCNET Local Area Network (LAN) communication is used to connect the operator interfaces to the panel(s).
• The Stage Link is the connection between the operator interfaces and the Mark V control panel(s). To accommodate long distances between the operator interface computers and the turbine control panel, the Stage Link may include fiber optic cables and repeaters in some cases.
• The operator interface can also be used to configure or modify the control, protection, monitoring, and logging functions of the interface computer's programs. Passwords are required to modify or configure these functions. Monitor sizes, color printers, laser printers, and an audible alarm horn are among the interface options.
