Write down everything, including the prefix (F, A, E, or B) and any decimal. Example: F 203.2 is different from F 203.
Rexroth PPC-R22.1 (VisualMotion) controller uses a specific set of fault codes to identify hardware, communication, and configuration issues. Common PPC-R22.1 Fault Codes Description Potential Cause / Remedy -01 to -2X Power-On State Errors Controller halted during boot. If stuck at , the CPU motherboard may be defective. F01 to F06 Optical Communication Errors
Issues with fiber optic cables connecting controller to drives. Inspect for cable damage or disrupted nodes. Address Recognition Error Duplicate or unset addresses in the fiber optic ring. Exceeding Driver Limit
Too many drives connected for the controller's maximum capacity. F15 to F18 Soft Fault (Parameter Loss)
CF card parameters missing or changed due to power outage or grounding issues. Restore from backup. F21 to F23 Debugging / Spare Parts
Mismatch between RAM data on the CF card and the motherboard. Usually requires a power cycle to resolve. F24, F27, F28 Memory Issues rexroth ppcr221 fault codes full
Internal RAM or memory addressing failure. Attempt a reset via power cycle. F31 to F40 Bus Communication Errors
Fieldbus connection (e.g., Profibus, DeviceNet) failure. Check bus cabling and terminator resistors. General Drive Fault
A connected drive is faulted. The PPC displays this as a catch-all; check individual drives for specific codes (e.g., F8xx). Drive Phase 4 Switch Error
Failed transition from Sercos phase 3 to 4. Often due to invalid drive parameters. Use or DriveTop to view invalid parameter lists. Diagnosis Tools SynTop / DriveTop

A common misconception is that the controller screen shows "everything." To get the "full" list of fault codes, you must utilize the controller's Diagnostic Buffer (Diagnosis History). A common misconception is that the controller screen
Step-by-Step Review of the Retrieval Process:
| Fault Code | Description | Probable Cause | Corrective Action |
| :--- | :--- | :--- | :--- |
| F3001 | Fieldbus Module Not Found | Communication module (e.g., Profibus, EtherCAT) loose or defective. | 1. Check module seating in the backplane.
2. Inspect ribbon cables/connectors. |
| F3005 | No Communication with Drive | Broken fiber optic cable or SERCOS interface error. | 1. Check fiber optic cables for bends/breaks.
2. Verify drive has power and is addressed correctly. |
| F3100 | PLC Communication Timeout | Master-Slave communication interrupted. | 1. Check network cables.
2. Verify termination resistors are correct. |
If the PPCR221 loses track of the motor’s rotor position, it will fault immediately to prevent runaway.
| Fault Code | Description | Common Cause | Immediate Action | | :--- | :--- | :--- | :--- | | F501 | Encoder Communication Error (EnDat) | Broken shield; faulty ribbon cable; noise interference. | Reseat encoder connector X8. Check for 5V supply between pins. | | F503 | Hall Sensor Invalid State | Three hall sensors giving an impossible pattern (e.g., 111 or 000). | Inspect hall sensor PCB inside motor. Replace if magnetized debris present. | | F510 | Resolver Mismatch | Motor feedback and drive resolver settings differ. | Compare P-0-0114 (Resolver poles) with actual motor. | | F512 | Speed Deviation Too High | Commanded speed vs. actual speed difference > threshold. | Mechanical binding; encoder coupling slipped. |
Pro Tip for F503: This is common in high-vibration environments. Use a syringe of electronic contact cleaner on the hall sensor connector. If the fault returns weekly, replace the motor feedback board.
