PPC-P01.1A-N-A3-NN-NN-FW EP

The PPC-P01.1A-N-A3-NN-NN-FW EP is a control unit manufactured by Bosch Rexroth Indramat for the PPC Controllers series. Installed in multi-axis drive cabinets, it coordinates motion sequences and peripheral I/O so production lines follow programmed paths and timing. Its industrial PC housing allows direct mounting beside drive amplifiers, and the 5 V logic supply ties the unit to the same low-voltage rail used by adjacent automation electronics.

The controller operates from a regulated input of 5 VDC and draws up to 1.5 A during peak computational load. A 8 MB SDRAM main memory holds the real-time operating system, while a dedicated 4 MB flash device stores the application image so code is retained when power is off. A 32-bit Power PC microprocessor executes interpolation, communication, and diagnostic tasks; its bus architecture connects to an additional 4 MB plug-in expansion module when programs exceed the primary space. This memory hierarchy permits large cam tables and PLC logic without paging delays, and the logic core is dimensioned for the cycle times required in high-speed packaging machines.

User data that must survive extended shutdowns is kept in a 4 MB SDRAM buffer battery-backed by the motherboard. Configuration bytes such as axis scaling are written to a 256 Byte EEPROM, and production counters reside in a 64 KB NVRAM so they are not lost during maintenance power cuts. Deterministic drive communication is handled by the integrated SERCON 816 Sercos controller, matching the series-1 hardware layout and design version 1 board revision. The industrial PC enclosure simplifies cabinet airflow planning, and the memory expansion socket lets the unit grow with process complexity without changing the field-wired backplane connectors.
