Rexroth Ppcr221 Fault Codes Full | !!better!!

The Rexroth PPC-R22.1 Go to product viewer dialog for this item.

(and associated R22 models) is a high-performance motion controller often used in SYNAX 200 and VisualMotion systems. Fault codes for these controllers are typically displayed on an H1 two-digit seven-segment display on the front panel. Overview of PPC Fault Categories

Fault codes on the PPC controller generally follow a specific classification based on the nature of the error:

Initialization Messages (-01 to -2x): These occur during the startup sequence and often indicate internal hardware checks or firmware loading status.

Hardware Errors (¥01 to ¥14): Critical hardware failures, such as internal circuitry or power supply issues.

Process Errors (F codes): These are operational faults ranging from communication loss to memory corruption. Common PPC-R Fault Codes and Troubleshooting Typical Cause & Remedy F11 - F14 Parameter Loss

Often caused by power outages or grounding failures affecting the CF card. Remedy: Restore the previous backup from the engineering software. F21 - F22 Debugging Errors

Typically appear during initial setup or commissioning. Remedy: Recheck the debugging process and configuration parameters. F23 Spare Part Error

Occurs when a replacement PPC module or component is incompatible. Remedy: Ensure the hardware version and firmware match the system requirements. F24, F27, F28 Memory Issues

Internal RAM or memory buffer errors. Remedy: Cycle the control power. If persistent, the hardware may be defective. F29 Password Error Invalid or incorrect password entry for system settings. F31 - F40 Bus Communication

Issues with fieldbus (e.g., SERCOS, PROFIBUS) communication. Remedy: Inspect fiber optic cables, connectors, and bus addresses. F98 Drive Fault

The most frequent code; indicates that at least one connected drive has an error. Remedy: Check the individual drive displays or use software like SynTop to find the specific faulty axis. Advanced Diagnosis with Software

For a complete diagnostic history, it is highly recommended to use Rexroth Engineering Tools:

SynTop / VisualMotion Toolkit: These allow users to interpret the detailed diagnostic parameters (e.g., parameter Y-0-0048) which provide more context than the two-digit H1 display.

F HW (18/19): These specific internal codes indicate hardware defective status, specifically regarding "CON_CYC-Signal" or general circuitry.

For detailed wiring and technical specifications, refer to the Rexroth PPC-R Project Planning Manual

Common Fault Categories & Meanings

  • Power Supply Faults

    • Cause: Undervoltage/overvoltage, supply instability, blown fuses, poor wiring.
    • Troubleshoot: Verify supply voltage at module, check fuses/terminals, inspect wiring for loose connections or corrosion.

  • Internal Electronics / Hardware Faults

    • Cause: Faulty PCB, damaged components, thermal stress.
    • Troubleshoot: Cycle power to confirm transient; check module temperature; if persistent, replace module or send for repair.

  • Sensor / Transducer Faults

    • Cause: Pressure sensor open/short, incorrect sensor wiring, failed transducer.
    • Troubleshoot: Measure sensor output/resistance; verify connector pins; substitute known-good sensor.

  • Valve / Actuator Faults

    • Cause: Coil open/short, valve jamming, hydraulic contamination.
    • Troubleshoot: Check coil resistance; inspect hydraulic fluid/filters; operate valve manually if possible; clean or replace valve.

  • Communication / Fieldbus Faults

    • Cause: Bus wiring errors, termination missing, address conflicts, protocol mismatch.
    • Troubleshoot: Verify bus voltage and wiring, check termination resistors, confirm node addressing and protocol settings, test with known-good node.

  • Configuration / Parameter Errors

    • Cause: Incorrect parameter values, calibration lost after power cycle.
    • Troubleshoot: Reload correct parameter set, restore from backup, re-calibrate per manual.

  • Temperature / Overload Faults

    • Cause: Excessive ambient or device temperature, continuous overload.
    • Troubleshoot: Improve ventilation, reduce duty cycle, check for blocked cooling paths.

  • Diagnostic / Watchdog Faults

    • Cause: Firmware or control loop errors, watchdog timer triggered.
    • Troubleshoot: Update/restore firmware, power-cycle device, consult Rexroth support if recurring.

2. How to Read the Fault Codes (The Real Method)

The PPCR221 does not have a 7-segment display. Faults are communicated via:

A. RUN/ERR LED Patterns (Hardware & System Bus):

| 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 |

B. Fieldbus Specific Errors (Most Common):

  • PROFIBUS DP (if equipped): The PPCR221 acts as a master/slave. Faults appear as BF (Bus Fault) LED flashing.
    • Code 0x0xxx: Station not ready.
    • Code 0x7xxx: Parameterization error (wrong GSD file).
  • PROFINET: Faults are read via the engineering tool (IndraWorks). Typical codes: 0xE000 (Link down), 0xE010 (Name mismatch).

C. The "User Faults" (80% of what you see): The PPCR221 runs CoDeSys 2.3. Any "Fault Code" shown on an HMI is almost certainly a custom variable (e.g., fault_code := 1234). You need the PLC project source code or a fault list exported from the program.

Final Thoughts: Mastering Your Rexroth PPCR221

Having the full list of Rexroth PPCR221 fault codes at your fingertips transforms reactive troubleshooting into proactive machine management. Bookmark this guide, print the table, and tape it inside your electrical cabinet door.

Remember these three golden rules:

  • Never reset a fault more than three times without investigating – you will blow the output IGBTs.
  • Document each fault with a timestamp – recurring weekly F501 points to cable flex fatigue, not a random glitch.
  • Use IndraWorks Ds for live diagnostics – the onboard display shows only 10% of available diagnostic data.

If you need the official Bosch Rexroth manual supplement for the PPCR221 (Document no. DOK-SUPPL*-PPCR221**-ITRS-EN), contact Bosch Rexroth Customer Service at 1-800-739-7684 (North America) or visit their download portal at www.boschrexroth.com/service.

Keep your hydraulics moving and your production lines running. No fault is unfixable with the right code list and a logical approach.

FAQ – Quick Answers

Q: My PPCR221 shows "F 000". What does that mean? A: No active fault. The drive is healthy. If the motor won't run, check your enable signal (terminal X4.2).

Q: Can I clear fault codes remotely via Ethernet? A: Yes. Send a control word bit (typically bit 7 of STW) via Profisafe or Modbus. But local reset is safer.

Q: Why do I get an F305 fault only at 3:00 AM? A: Likely a shared 24V power supply dropping voltage due to a cleaning robot or other automated system starting up. Install a dedicated 24V, 10A PSU for the PPCR221 alone.

This is a specific request, as Bosch Rexroth does not publicly release the full PPCR221 (Part Number: R911170328) fault code list in a single consumer-accessible manual. The PPCR221 is a PLC/PAC (Programmable Automation Controller) running the Rexroth IndraLogic (CoDeSys 2.3) firmware.

The fault codes you see are a combination of system diagnostics (I/O, Bus, CPU) and user-programmed errors.

Here is the best practical guide to finding, interpreting, and troubleshooting PPCR221 fault codes.

Final Professional Advice

Call Rexroth Service (1-800-REXROTH in US) with these details:

  • Part number: R911170328 (PPCR221)
  • Firmware version (from IndraWorks online)
  • Exact LED state (RUN/ERR blinking pattern)
  • Exact error message (e.g., "Fieldbus error 0x7E10")

They will give you the diagnostic matrix directly. For the application-specific codes (e.g., "Fault 47: Motor overload"), you must get the machine builder's documentation or the original *.pro project file. The Rexroth PPC-R22

Do you have a specific fault code number or LED pattern you are seeing right now? If you share it, I can interpret it.

In the world of Rexroth motion control, the PPCR221 (PPC-R22.1) is a powerhouse servo module that acts as the "brain" for multi-axis machines. When this brain encounters a problem, it communicates via a specific set of diagnostic codes.

Here is the "story" of how to read and resolve the various fault states of a PPCR221 controller. 1. The Startup Phase: Initialization Messages

When you first flip the switch, the PPCR221 goes through a self-check. If it freezes before it even starts, look at the small display for negative numbers: Codes -01 to -2x: These are initialization stages.

The "State -08" Trap: If the controller hangs here, it often points to a malfunctioning CPU on the motherboard.

Fix: This usually requires a repair or replacement of the control unit itself. 2. The Optical Ring: Communication Errors

The PPCR221 often talks to its drives through fiber optic cables. If this "circle of conversation" is broken, you'll see "F" codes: F01 to F06: These signal a break in the optical fiber ring.

F07: "Address Recognition Error." This happens if two drives have the same address or an address is missing.

F08: You've tried to connect more drives than the optical ring can handle.

Fix: Trace the cables. Look for a "red light" on the drive's optical card; that’s usually where the break is. 3. The Memory Vault: CF Card & Parameter Errors

The PPCR221 stores its "memories" (parameters) on a CF card.

F15 to F18: "Soft Faults." These usually crop up after a sudden power outage or lightning strike that scrambles the data on the CF card.

F23: The "New Part" code. This appears when you swap a motherboard but keep the old CF card; the data doesn't match.

Fix: Restoring a backup or a simple power cycle (for F23) usually sets things right. 4. The External Messenger: Bus Communication

If the PPCR221 can't talk to the rest of the factory (via PROFIBUS or Ethernet): F31 to F40: These are Bus communication errors.

Fix: Check your fieldbus cables and ensure the master PLC is sending the right signals. 5. The "Rich" Code: F98

The most common code you will see is F98. This is a catch-all signal that says, "One of my connected drives is broken, but it's not my fault".

Fix: You must leave the PPCR221 and check the individual drive displays. Using SynTop software is the fastest way to pinpoint exactly which drive is crying for help.
