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.

Common Rexroth PPC Fault Codes and Their Solutions * 1. Power On State Errors (Codes -01 to -2X) Upon powering the PPC controller, Wake Industrial Main Failure Codes of PPC Controller and Removal Method 14 Oct 2019 —

The Rexroth PPC-R22.1 (and the specific variant PPCR22.1) uses a 4-character alphanumeric display to communicate its operating state and error conditions. These codes are divided into startup/initialization states (negative numbers) and functional fault codes (typically starting with "F" or "E"). 🔌 Power-On / Startup Errors

If the controller stops at any of these negative numbers during power-up, it indicates a hardware or initialization failure. Common Cause / Solution -01 to -07 CPU Initialization CPU or RAM test failed. Replace control unit. -08 CPU Malfunction Often indicates a motherboard or processor failure. -10 to -2X System Startup Problem loading the operating system from the CF card. E1 Processor Fault

Static discharge or hardware error. Check RS-232 for details. E2 RAM Error Programming module RAM is defective or poorly seated. E3 / E4 Watchdog Trigger

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

F01 - F06: Optical Cable Errors. Communication lost between the PPC and a drive. Check for broken fiber optics or a red light on the driver's optical card.

F07: Address Recognition Error. Duplicate or unset addresses found in the optical ring.

F08: Driver Limit Exceeded. Too many drives connected to one optical ring.

F31 - F40: Bus Communication Errors. Issues with the fieldbus (Profibus/DeviceNet) interface. 💾 Parameter & Memory Faults How easy is it to decipher the "full" list of codes

F15 - F18: Soft Fault. Corruption or loss of parameters on the CF card. Often caused by sudden power loss. Solution: Restore from backup.

F24, F27, F28: Memory Issues. Internal memory access failure. Try a power cycle to reset.

F29: Password Error. Invalid or missing password for protected parameters. ⚙️ Hardware & Drive Faults

FHW (18/19): Hardware Defective. The PPC internal hardware is faulty (Sync signal lost).

F98: Global Drive Fault. A generic code meaning one of the connected drives has a fault. You must check the individual drive displays or use SynTop software to find the specific axis causing the error. ⚠️ Warning & Status Codes

These do not necessarily stop the machine but indicate a transition or a near-limit state.

bb: Ready for Operation. Control voltage is present, and no errors exist.

Ab: Drive Ready. Power is on and the system is ready to enable.

AF: Drive Enabled. The system is currently active and following commands.

P0, P1, P2, P3: Communication Phases. Normal startup phases for SERCOS communication. If it gets stuck here, there is a configuration mismatch.

E-xxxx: Warning Messages. For example, E8260 (Torque Overload) or E226 (Undervoltage). These warn that a shutdown is imminent unless the condition is corrected. 🛠 Troubleshooting Steps

Check the CF Card: Ensure the CompactFlash card is fully seated and the firmware version matches your application.

Inspect Fiber Optics: Look for tight bends or cracks in the SERCOS cables. The "H2" LED on the front panel indicates communication status.

Use SynTop / IndraWorks: Connect via the serial port (X10) to read the full diagnostic buffer. The 4-digit display is limited; the software provides the exact reason for "F98" or "F-codes."

Reset S2: Use the small reset button (S2) on the front panel to force a reboot if the system hangs during initialization.

Which specific code is your PPC showing right now? If it is stuck on a negative number or a specific "F" code, I can give you the exact pinout or parameter to check.

(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 Code | Description | Probable Cause

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.
