Primary Functions
The DSPX board acts as the central controller for essential operations, including bridge and motor regulator control for Innovation Series drives, as well as overseeing gating functions critical to their operation. Additionally, it manages generator field control functions integral to the EX2100 Excitation Control.
Logic, Processing, and Interface Functions
Beyond its primary control functionalities, the DSPX board provides logic processing and interface capabilities, ensuring efficient communication and coordination between various system components and functions.
Customized Functions via Field Programmable Gate Arrays (FPGA) or ASICs
Specialized functions on the DSPX board are facilitated through custom logic implemented in Field Programmable Gate Arrays (FPGA) or Application-Specific Integrated Circuits (ASICs). These components are equipped with supporting circuits as needed to carry out specific operations efficiently.
Integration into Board Rack via Connector (P1)
The DSPX board is installed in the board rack and interfaces with the system's backplane through a 4-row, 128-pin DIN connector labeled as P1. This connector serves as a primary point of connection, enabling communication and data transfer between the DSPX board and other system components through the backplane.
Additional Connectors for External Communication
The DSPX board features two additional connectors for external communication and monitoring purposes:
- P5 - DSP Emulator Port: This port allows connectivity for a DSP emulator, enabling debugging, testing, and emulation of the DSPX board for development or troubleshooting purposes.
- P6 - Engineering Monitor Port: This port serves as an interface for engineering monitoring tasks, providing access to monitoring and diagnostic functions related to the DSPX board's operations.
Indicating Lights
- DS1 - FAULT LED (Red):
- ON or Flashing: Indicates the occurrence of a fault in the system or when the system is undergoing a reset process. The red LED illuminates steadily or blinks to alert operators about the presence of a fault or during system reset procedures.
- OFF: Indicates the absence of any faults within the system. When the red LED remains off, it signals that no faults are currently detected or active.
- DS2 - STATUS LED (Green):
- Flashing: Signifies that the system is operational and running. The green LED flashes intermittently when the system is in operation, providing a visual cue of its active status.
- ON: Indicates that the system has stopped or is currently not running. When the green LED remains steadily illuminated, it denotes a stopped state of the system or that the system is not currently operational.
- OFF: Informs about the occurrence of a fault in the system or during a reset process. Similar to DS1, the green LED remains off when a fault is present or during system reset procedures.
