Product Review: Bosch Rexroth PPC-R22.1 (PPCR221) Controller

Focus: Diagnostic Capabilities and Fault Code Management

Executive Summary

The Bosch Rexroth PPC-R22.1 (often referred to as the PPCR221) is a robust, industrial-grade Programmable Logic Controller (PLC) designed specifically for hydraulic and motion control applications. While the hardware is renowned for its durability in harsh environments, its true value lies in its diagnostic system. For maintenance engineers and technicians, understanding the "full" scope of its fault codes is the difference between hours of downtime and a quick reset.

• IndraWorks DS → Diagnostics → Fault Memory → Last 8 faults

• Provide the exact fault code table for PPCR221 (firmware-specific) — requires the module’s firmware version or manual PDF.
• Draft a printable troubleshooting flowchart.

Solution: Perform a full power cycle of the PPC controller to reset memory issues. For password errors, verify your credentials against the system’s security parameters. 4. Bus Communication Faults (F31 – F40) rexroth ppcr221 fault codes full

Saving Tip: Bookmark this article. The "full" list of Rexroth PPCR221 fault codes is rarely found in a single manual—they are split across drive, power, and communication supplements. Product Review: Bosch Rexroth PPC-R22

Do not ignore B001. If you see this after a power outage, the drive’s battery-backed RAM may have failed. You must rewrite parameters manually. IndraWorks DS → Diagnostics → Fault Memory →

| LED State | Meaning | Likely Fault Code Category | | :--- | :--- | :--- | | Green RUN, Red ERR OFF | Normal operation | No fault | | Green OFF, Red ON | Hardware fault (internal) | CPU error, watchdog | | Green OFF, Red flashing (1Hz) | STOP state (no program) | Configuration missing | | Green ON, Red flashing (2Hz) | Bus communication error (Sercos, PROFIBUS, PROFINET) | Fieldbus fault | | Both flashing alternately | Firmware update / Bootloader mode | Recoverable via service tool |

Acknowledge via Signal: Many systems are programmed to clear the fault once a dedicated "Reset" or "Enable" digital input is toggled from Low to High.
