Product Description:

The PPC-R22.1N-T-Q1-P1-NN-FW is a programmable control unit produced by Bosch Rexroth Indramat for the PPC Controllers series. Mounted alongside Rexroth drive modules, it executes motion sequences, fieldbus coordination, and diagnostic tasks that support industrial automation cells. The module houses its electronics in a compact RECO-style enclosure and mounts on a 24 VDC power rail inside a protected cabinet, where it serves as the central logic layer between higher-level PLCs and the Sercos, Profibus, and Ethernet communication networks of a machine.

Its primary power requirement is 24 VDC, and under peak load the unit draws up to 1.2 A, so the cabinet supply must deliver enough power for stable operation. A local flash store of 32 MB retains control programs and configuration data even when power is removed. For fieldbus duties, the integrated Profibus master negotiates traffic at up to 12 MBaud, while the optical Sercos interface exchanges drive telegrams at 16 MBaud to preserve deterministic cycle times. Internal measurement channels are supervised by the DAQ03 board, and its 5 V rail is limited to 700 mA while loads that exceed the 4 Vpp ripple limit are rejected to protect logic integrity.

For higher-level networks, an RJ45 connector supports 100 MBaud Ethernet and communicates through TCP port 5001, permitting cross-communication with engineering or SCADA hosts. Supplied as design version 1, the hardware offers 3 vacant expansion bays that accept future I/O or fieldbus cards without requiring changes to compiled projects. The controller carries an IP20 rating, so it must be installed in an enclosed panel where airflow keeps internal ripple within limits. With a mass of only 1.3 kg, it places minimal strain on DIN-rail hardware while still supporting a 40-drive capacity and the two serial links used in complex motion platforms.
