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
Internal RAM or memory addressing failure. Attempt a reset via power cycle. F31 to F40 Bus Communication Errors rexroth ppcr221 fault codes full
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
: These software packages are essential for viewing the detailed "rich meaning" behind general codes like Status LEDs
: A red flashing LED on the controller indicates a system error, while a yellow flashing LED indicates a warning.

Step 1: Identify the fault type
Step 2: Connect with IndraWorks Engineering Is the PLC in STOP
16#4002 = memory error).Step 3: Interpret Common System Error Codes (Hex)
| Hex Code | Description (System) | Action |
| :--- | :--- | :--- |
| 16#0001 | Watchdog overflow | Increase task cycle time or optimize code. |
| 16#2001 | No user program | Download project. |
| 16#3002 | I/O bus failure (K-Bus/E-Bus) | Check terminal bus coupler, power supply. |
| 16#4003 | Retain data corrupted | Clear retain memory and reload defaults. |
| 16#5005 | Sercos ring error | Check fiber optic cables, ring configuration. |
| 16#6xxx (e.g., 0x6A01) | PROFIBUS DP: Station not found | Check address switch, cable termination. |
The codes are grouped into four logical categories: Overcurrent & Overload (F10x–F20x), Voltage & Power Supply (F30x–F40x), Encoder & Feedback (F50x–F60x), Communication & Fieldbus (F70x–F90x), and System & Internal Errors (A/B Codes).
The controller distinguishes between two primary states, which dictates how the code is logged and displayed:
