Product Description:

The PPC-P11.1N-N-P1-N1-NN-FW control unit is produced by Bosch Rexroth Indramat within the PPC Controllers series. Packaged in an industrial PC housing, it functions as the motion and communication core for multi-axis cells, generating position commands, collecting feedback, and coordinating fieldbus exchanges between drives and higher-level automation controllers. This arrangement allows one unit to manage both machine logic and axis-related communication from a central location. It is suited to installations where several servo axes and plant networks must operate in step.

Internally, a 32 MB flash device stores user code, and no additional memory expansion slot is fitted. The logic section provides a regulated 1400 mA supply on the 3.3 V rail to power internal buses and attached option hardware. A dedicated pulse-output module provides sixteen outputs, and each connector carries eight channels for straightforward wiring. These outputs refresh every 250 µs, which supports close timing alignment with drive cycles. The controller can coordinate 40 drives, and its Profibus-DP master port uses an optically isolated RS-485 layer with a 9-pin D-Sub plug, four status LEDs, and a data rate of 12 MBaud for deterministic communication.

Hardware built to Design Version 1 delivers 450 mA on the 5 V plane for panel indicators and the Profibus transceiver, while each pulse line can source 250 mA at 24 V for direct actuation of solenoids or lamps. The fitted PLS option card NSW01 occupies the single expansion slot and brings the pulse-output connections to the controller front edge, so separate breakout boards are unnecessary. Rear-mounted service connectors keep the industrial PC layout compact and keep cabling grouped on one side of the housing. The isolated bus interface helps reduce ground-loop problems when the unit operates across multiple cabinets. This layout also supports cleaner separation between control wiring and power-related connections.
