Solution: Check for hardware failures. This could indicate a need for professional repair.

| Fault Code(s) Displayed | Description / Meaning | Probable Cause(s) | Troubleshooting & Resolution | | :--- | :--- | :--- | :--- | | – 01 to – 2X | Status codes during PPC power-on self-test (POST). | Normal operation; these codes flash briefly as the controller initializes. | No action required if the code proceeds to a normal state (e.g., BB or P0 - P3 ). If the process stops at a specific code, it indicates a hardware initialization problem. | | – 08 | Power-on self-test halt. | The CPU on the PPC controller motherboard is likely defective. | This code suggests a fatal hardware failure. The controller likely requires component-level repair or replacement by a qualified service center. | | BB , P0 , P1 , P2 , P3 | Normal communication states (e.g., "BB" = ready and waiting for commands). | These are normal operational modes, not faults. | No action needed. | | F01 to F06 | Communication faults on the SERCOS II optical fiber ring. | Issues with the fiber optic cables, connectors, or interface cards. | 1. Inspect all fiber optic cables for physical damage or kinks. 2. Clean all fiber optic connectors using a proper cleaning kit. 3. Check the SERCOS ring configuration for a broken loop. 4. Look for a red LED on the drive's communication card to locate the fault node. | | F07 | Unrecognized address in the SERCOS ring. | Duplicate or unassigned addresses for drives in the system. | Verify and correct all drive addresses in the SERCOS network configuration. | | F08 | Maximum drive count exceeded. | The number of drives in the SERCOS optical cable ring exceeds the limit of the PPC controller. | Reduce the number of drives in the ring or reconfigure the system if possible. | | F09 | PPC controller software fault. | A transient software error or a bug in the controller's firmware. | Perform a full power cycle (turn the controller off, wait 30 seconds, then turn it back on). If persistent, update or reinstall the controller firmware. | | F15 to F18 | Indicates a "soft fault" (configuration or parameter error). | Incorrect parameter settings in the PPC controller software or the drive parameters. | 1. Review recently changed parameters. 2. Restore a known good backup of the controller's configuration. 3. Re-commission the axis in question following the correct procedure. | | E825 | Overvoltage fault. | High line voltage, deceleration energy from the motor back-feeding into the DC bus, or a faulty braking resistor/regenerative power supply. | 1. Check the incoming line voltage. 2. Verify the braking resistor is functional and correctly sized. 3. Inspect the power supply module for internal faults. | | F277 | Overcurrent fault. | Short circuit in motor cables, motor winding damage, incorrect motor parameters, or a failed output stage in the drive. | 1. Disconnect the motor and test the drive; if the fault clears, the issue is likely external (motor/cables). 2. Check motor cables for shorts or grounding issues. 3. Verify motor parameters match the actual motor. | | F873 | Power drive board fault. | Internal failure of the drive's power electronics (e.g., IGBTs, gate drive circuits). | This fault usually requires replacing the drive's power section or the entire drive unit. | | F267 , F860 | General software or parameter faults. | Defective software checks, parameter range violations, or communication mismatches. | 1. Review the drive/controller logs for more details. 2. Restore default parameters and reconfigure. 3. Update firmware to the latest version. | | F211 | DISC-Error. | A hardware error related to the drive's internal communication bus. | This is a hardware fault that requires drive replacement or component-level repair. | | 4000 to 4999 | Internal software errors (e.g., invalid unit, invalid equipment ID, invalid action). | Software bugs in the PPC controller's operating system or the user's logic program. | 1. Contact Rexroth support with the specific code for a software patch. 2. Review and debug the user's PLC/Motion program. | | 4151 | PPC Handler sanity check failure. | Severe software inconsistency detected by the PPC's internal diagnostic routines. | Requires in-depth debugging or firmware reinstallation; consult Rexroth support. | | Sxxx (e.g., S123 ) | Four-digit "S" code (e.g., Sxxx ). | The letter "S" followed by three decimal digits indicates a four-digit error code. | Consult the specific error code table for the controller's firmware version. | | General PLC Errors (MTX, Minor, etc.) | Classified by severity: MTX (fatal), Minor (non-fatal), Servo Loop & Drive Fault , etc. | Varies widely, ranging from incorrect cable connections to software programming errors. | Identify the specific error subclass and follow the recommended resolution, which often involves checking connections and reviewing the program code. | rexroth ppcr221 fault codes full

Fault codes are alphanumeric strings that indicate specific problems or errors within the controller. They serve as a diagnostic tool, allowing users to pinpoint issues and perform corrective actions. Rexroth PPCR221 fault codes are typically displayed on the controller's screen or through a diagnostic interface.

The codes are grouped into four logical categories: , Voltage & Power Supply (F30x–F40x) , Encoder & Feedback (F50x–F60x) , Communication & Fieldbus (F70x–F90x) , and System & Internal Errors (A/B Codes) .

These errors are related to the logical configuration of devices on the fiber optic ring. The supply voltage to the module has dropped

Here are some common fault codes associated with the Rexroth PPCR221 controller:

When a fault code flashes on the screen, follow these steps to narrow down the issue: Step 1: Check the Diagnostic LED Identify if it's a critical fault (F) or a warning. Step 2: Clear the Fault

| 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. | General Drive Fault Solution: Check for hardware failures

Hardware watchdog failure; typically requires unit replacement. System Fault Codes (F-Codes) F-codes represent failures that usually stop operation. 🌐 Optical & Communication Faults
