Product Description:

The PPC-R22.1N-N-G2-V2-NN-FW is a motion and logic control unit produced by Bosch Rexroth Indramat for the PPC Controllers series. This DIN-rail device coordinates axis drives and peripheral I/O inside automated machinery by processing position feedback, exchanging fieldbus telegrams, and issuing step sequences to connected drive modules. When mounted in a protected cabinet, it provides centralized control of multiple servo axes without requiring additional PC hardware. That arrangement suits packaging, printing, and handling systems where compact cabinet installation and deterministic motion control are important.

The controller draws its logic power from a 24 VDC cabinet bus and tolerates line ripple up to 4 Vpp, so a standard regulated supply is sufficient. Under peak load, the electronics consume 1.2 A, which helps determine the required supply capacity. Machine I/O is handled through 3 digital inputs for status signals and 2 digital outputs rated for 0.5 A each, allowing direct actuation of opto-isolated relays or contactors. The internal LAG encoder card accepts incremental feedback on two master channels and processes count rates up to 200 kHz, giving the processor fine position resolution for fast axes. The unit uses design version 1 hardware, and the circuit boards are housed in a compact RECO enclosure that supports backplane stacking.

For higher-level networking, the controller carries a DeviceNet slave interface that exchanges process data with central PLCs over the CAN physical layer. The enclosure has an IP20 rating, so the unit must be installed inside a closed rack or cabinet. At 1.3 kg, the module is light enough for slide-in card frames and places little mechanical stress on the backplane. No memory expansion sockets are installed, and the board set omits onboard Ethernet, so operation is limited to the available bus interface and local control resources. This layout keeps the controller focused on deterministic motion tasks rather than general-purpose computing functions.
