Country of Origin
This processor is engineered and manufactured by ABB Switzerland Ltd. in Turgi, the global center for ABB’s high-power electronics and excitation technology.
Application Fields
The PPC905AE101 is designed for applications where standard PLCs are too slow:
- Large AC Drives: The core controller for MEGADRIVE-LCI and high-power frequency converters.
- Excitation Systems: Managing the UNITROL 6000 series for large power plant generators.
- Static Frequency Converters (SFC): Converting grid power for railway systems (e.g., 50Hz to 16.7Hz).
- HVDC Systems: Controlling the firing pulses for High Voltage Direct Current transmission valves.
- Renewable Energy: Managing grid-tie inverters for utility-scale solar and wind installations.
Product Usage Instructions
- Handling: This is a highly sensitive electronic component. Always use an ESD wrist strap and follow anti-static procedures during installation.
- Mounting: Insert the module into the designated slot of the AC 800PEC subrack. Ensure the module is pushed fully into the backplane before tightening the front panel screws.
- Optical Links: If your application uses fiber optic communication for remote I/O, ensure the fiber ends are clean. The optical ports are critical for the low-latency feedback required in power electronics.
- Firmware Loading: Configuration is typically done via MATLAB/Simulink or ABB’s proprietary engineering tools. Ensure the firmware version matches the rest of the control system to avoid communication mismatches.
- Cooling: Ensure the subrack’s forced-air cooling system is functional, as high-speed processors generate significant heat during operation.
Product Technical Description
Technically, the PPC905AE101 is a “Hybrid Controller.” It bridges the gap between the digital world of a DCS and the analog-like speed required for firing thyristors or IGBTs. It features a powerful FPGA (Field Programmable Gate Array) that handles time-critical tasks like pulse width modulation (PWM) and fast fault protection, while the RISC processor handles higher-level control tasks and communication. This “dual-layer” processing allows the unit to respond to grid disturbances or internal faults in microseconds, preventing damage to expensive power semiconductors.
Q&A (Common Questions)
Q: What is the difference between PPC905 and standard AC 800M processors? A: The AC 800M (like the PM866) is designed for general process control with cycle times in milliseconds. The PPC905 (AC 800PEC) is designed for power electronics with cycle times in microseconds.
Q: Can I replace a PPC905AE101 with a PPC907? A: Not directly. While they are in the same family, different model numbers (905 vs 907) usually signify different I/O densities, processing power, or physical pinouts. Always match the part number exactly.
Q: Why is the “Error” LED flashing after installation? A: This often indicates a “Version Mismatch” between the software on the processor and the configuration in the system rack. It may also indicate a missing fiber optic link.
Q: Does the unit store data logs locally? A: Yes, the PPC905 has integrated transient recorders that can capture high-speed data during a fault for later analysis in ABB’s diagnostic software.
