You will speak with a real human immediately. A Rexroth PPC is the central motion controller in a SYNAX 200 system. It coordinates synchronized axes, exchanges real-time data with Indramat drives over the SERCOS fiber-optic ring, and can supervise the PLC, master axes, host interfaces, fieldbus connections, and PPC-link. A code on the PPC display can therefore identify a problem within the controller or another device reporting through it.
Use this guide to translate the complete display code, locate the associated diagnostic parameters, and follow the corrective action for the exact subcode. Record the display and diagnostic values before resetting the controller. A clear command removes an active message from the diagnostic source, but it does not correct the parameter, hardware, feedback, or communication condition that generated the fault. Even though Bosch Rexroth Indramat PPC Controllers are designed for reliable performance, they may encounter an occasional issue. Wake Industrial is not an authorized distributor for these manufactured goods and Wake Industrial does not provide OEM technical support.
How to Use This Rexroth PPC Fault-Code Guide
Work through the displayed code in order and preserve the diagnostic evidence before clearing it. The four items below provide the fastest route from the front-panel display to the correct fault-table entry.
Step | What to Record or Check | Why It Matters |
1 | Front-panel display and machine state | Separates a normal startup or operating-state display from an active fault. Note whether the PPC is still initializing or has reached operating mode. |
2 | Corrective action for the exact code or subcode | Prevents a broad fault-family label from being mistaken for the remedy to a specific parameter, communication, or hardware condition. |
3 | Source-specific clear input | Removes the active diagnostic only after the reported cause has been corrected. |
Common Rexroth PPC Fault Codes and Their Solutions
1. Power On State Errors (Codes -01 to -2X)
Upon powering the PPC controller, if it halts at a specific state and doesn't proceed, it could indicate a problem with the CPU on the controller motherboard. For instance, if it pauses at state -08, the CPU might be malfunctioning.
Solution: CPU replacement or control unit repair may be required. If your PPC-R02.2N-N-NN-P2-NN-FW is experiencing any issues, contact Wake Industrial today.
2. Optical Cable Communication Errors (Codes F01 to F06)
These codes indicate issues in the PPC's optical cable communications, which connects the controller to the driver.
Solution: Inspect the optical cable connections, identify any disrupted node, and check for any flashing or constant red light on the optical cable card of the driver at the faulted node.
3. Address Recognition Errors (Code F07) and Exceeding Driver Limit (Code F08)
Code F07 indicates the presence of unrecognized addresses, such as duplicate or unset addresses in the optical cable ring. Code F08 signifies that the number of drives in the optical cable ring exceeds the maximum limit.
Solution: Ensure unique, correct addressing for each device and adhere to the controller's maximum driver limit.
4. Soft Fault Errors (Codes F15 to F18)
These codes appear when there are changes or loss in the parameters of the PPC controller's CF card, often due to sudden power outages, cabinet grounding system failures, or thermostatic element lightning.
Solution: Restoring the previous backup normally resolves this issue.
5. Debugging and Spare Parts Errors (Codes F21 to F23)
Codes F21 and F22 usually appear during debugging, while code F23 is common when customers replace PPC spare parts.
Solution: Recheck the debugging process and ensure compatibility of spare parts.
6. Memory Issues (Codes F24, F27, F28) and Password Settings (Code F29)
Codes F24, F27, and F28 indicate memory problems, whereas code F29 is related to password settings.
Solution: Power cycle the PPC controller to reset memory issues. For password setting problems, ensure you are using correct and valid passwords.
7. Bus Communication Errors (Codes F31 to F40)
These codes indicate problems with bus communication.
Solution: Check the bus connection and address potential communication issues.
8. Drive Fault (Code F98)
If any of the connected drives encounters a fault, the PPC controller will display code F98.
Solution: Use SynTop software to identify the faulty driver and apply the corresponding solution. This software not only displays the fault information of the PPC controller but also the driver.
PPC Diagnostic Parameters
PPC diagnostic parameters are internal records that provide more detail than the short fault code shown on the controller display. The main parameters are Y-0-0046, which identifies where the error originated, Y-0-0047, which provides the diagnostic text, and Y-0-0048, which supplies the corresponding error number.
In simpler terms, the display code works like a warning light on a vehicle, while the diagnostic parameters explain what triggered that warning. Additional parameters can show when the error occurred, which settings are invalid, whether communication failures have accumulated, and whether controller temperature or a connected drive contributed to the problem. Reading these values before clearing the fault gives technicians a clearer starting point for troubleshooting.

Startup, Operating-State, and Hardware Displays
Initialization codes are expected to advance as the PPC runs its boot sequence. If an initialization number remains on the display, the stalled display indicates an initialization failure. P0 through P3 and bb identify normal control states rather than fault numbers.
Display | Meaning | Interpretation or Action |
-01 | FLASH checksum test | Normal during initialization if the display continues to advance. |
-02 | SDRAM test | Normal during initialization if the display continues to advance. |
-04 | Extended CRC32 checksum test | Normal during initialization if the display continues to advance. |

-20 to -2x | SYNAX system initialization | Normal during initialization if the display continues to advance. |
IFS | File-system or integrated-PLC initialization | Normal during initialization if the display continues to advance. |
P0 | PPC initialization mode | Status display. No fault is indicated by error number 0. |
P1 | SERCOS communication phase 1 | Status display. No fault is indicated by error number 0. |
P2 | PPC parameter mode | Status display. No fault is indicated by error number 0. |
P3 | SERCOS communication phase 3 | Status display. No fault is indicated by error number 0. |
bb | PPC operating mode | The PPC has reached operating mode. |
¥01¥ to ¥14¥ | Hardware error detected during the internal test | Replace the PPC or PSM identified by the machine configuration and submit it for service. |
How to Clear PPC Fault Codes in Operating Mode
Once the PPC has reached operating mode, the manual assigns a separate clear input to each diagnostic source. Use the input associated with the source that reported the error after the underlying condition has been corrected.
Error Source | Clear Input | Function |
Master-axis error |
| Clears the master-axis error and removes it from the active diagnosis when that axis supplied the diagnostic. |
Drive error |
| Clears the error for drive address # and removes it from the active diagnosis when that drive supplied the diagnostic. |
System error |
| Clears the system-error category identified in the fault tables. |
Communication error |
| Clears errors associated with external communications, including 3964R and fieldbus interfaces. |
PPC-link error |
| Clears or acknowledges a PPC-link error on the PPC. |

When PPC Repair, Refurbishment, or Replacement May Be Required
Parameter, configuration, and communication faults should be investigated at the named parameter or interface before a controller is removed. Correcting the underlying setting, wiring, address, drive condition, or communication problem may return the system to operation without replacing the PPC.
Hardware-test displays and a PPC that remains stalled during initialization require a different response. A PPC-R22.1N-T-NN-P2-NN-FW could have a different operational error than a base PPC-R22.1N. When the exact table entry directs replacement of the PPC, DAQ board, PSM, or related control hardware, or when the same hardware fault returns after restart, preserve the diagnostic record and arrange a repair evaluation or compatible replacement.
