Product Description:

The PPC-R22.1N-T-NN-B2-NN-FW is a control unit produced by Bosch Rexroth Indramat for the PPC Controllers series. Acting as a programmable motion coordinator, the module resides on a Sercos ring and distributes set-point data and diagnostics to multiple drives in an automated cell. By centralizing sequencing, interpolation, and axis synchronization, the unit reduces PLC load and permits tighter path control in packaging, printing, and material-handling machinery.

Electrical input for the controller is 24 VDC, and internal circuitry tolerates up to 4 Vpp of ripple on that line, so regulated low-voltage supplies must be selected accordingly. Under full bus traffic and I/O activity, the board draws a maximum of 1.2 A, a figure that helps size cabinet power distribution. An onboard Ethernet port is installed and negotiates at 10/100 MBaud for programming or supervisory links, while two RS-232 serial ports serve external serial devices. Motion commands leave the unit over a Sercos optical ring, and the controller can supervise up to 64 Sercos drives without additional hardware. For conventional I/O networks, an Interbus slave interface of type IBS03 is integrated, and this design does not include memory expansion.

Mechanical characteristics suit low-depth electrical enclosures. The RECO housing is 165 mm deep and 84 mm wide, and it mounts on a DIN rail alongside other Rexroth I/O. Despite its feature set, the unit weighs only 1.3 kg, which helps keep handling simple during installation. The protection rating is IP20, indicating finger-safe terminals but no sealing against moisture, so installation must remain inside a closed cabinet with adequate airflow. Three back-plane expansion connectors give the controller 3 user slots for specialty modules, and design version 1 is supplied without factory-installed option cards.
