Product Description:

The PPC-R01.2N-N-B2-FW is a compact control unit manufactured by Bosch Rexroth Indramat as part of the PPC Controllers series. Installed in multi-axis or process stations, the unit executes program logic, sequencing, and communication tasks so higher-level PLCs can coordinate drives and sensors from a single node. It is suited to applications that need centralized handling of drive commands, signal processing, and machine-state communication within one compact housing. The platform uses the bus structure and power arrangement common to this controller line, which helps the module fit into established cabinet layouts.

The controller operates from a nominal supply of 24 VDC, and the internal electronics draw no more than 0.7 A. This modest current demand allows the device to share a regulated low-voltage rail with nearby automation components when the power budget is planned correctly. The unit provides 3 digital inputs with opto-isolation and 2 digital outputs for status signaling such as motion acknowledgment or fault indication. With external dimensions of 41.5 × 192 × 150 mm, the module occupies one slot width in a standard 200 mm rack. Its enclosure has an IP20 rating, so it is intended for installation inside a closed electrical cabinet rather than for exposed mounting on the machine.

The control section mounts as a RECO unit, which locks onto a DIN rail and aligns the bus connector automatically with adjacent modules. Automatic connector alignment helps the module seat correctly beside neighboring units and supports orderly rack assembly. Data exchange with the supervisory PLC passes through the Interbus fieldbus slave interface IBS03, providing cyclic communication without a separate gateway. At 1.1 kg, the module places little load on cabinet structures during installation or removal. The product is in Series 1, which identifies the early production version of this controller line.

Fault code on display What it means First thing to check / do
F HW (19) PPC hardware-self-test failed Cycle power; if F HW (19) re-appears, replace the PPC module. 
F01 (01) SERCOS ring break Inspect fiber-optic cables & connectors, close the ring, reset PPC. 
F02 (02) No drives detected on SERCOS Check drive power, ID plugs, and addresses; re-initialise phase 1. 
F03 (03) Error when switching to phase 3 A drive did not acknowledge; view drive diag, fix, then re-enter phase 3. 
F04 (04) Can’t switch to operating mode Parameter mismatch; verify C-0-0086, number of drives, restart. 
F06 (06) Fiber-optic ring not closed Swap IN/OUT plugs or replace damaged fiber to complete loop. 
F07 (07) Drive addresses wrong Set unique SERCOS IDs (ID plug or keypad) - addresses 1…40 only. 
F08 (08) Max. number of drives exceeded Reduce attached drives or upgrade to PPC-R02 (two-slot) controller. 
F09 (09) Fatal internal error – PPC reset req. Save log with SynTop; power-cycle; replace controller if recurrent. 
F TN (25) PPC in test-mode “zero bit stream” Clear test mode bit C-0-0038, initialise, then restart. 
Controller Model Slots in RECO rack Field-bus & option code Typical use

Code (display) What it means
F HW (19) PPC hardware-self-test failed
F01 (01) SERCOS interface – ring break (fiber ring open)
F02 (02) SERCOS interface – no drives connected
F03 (03) Error when switching to phase 3 (drive reported diagnostic)
F04 (04) Error when switching into operating mode
F06 (06) Fiber-optic ring not closed (Tx/Rx crossed or cable break)
