These codes trigger when the PPC controller experiences an interruption or corruption in its operating parameters.
3. Processor Memory & Security Restrictions (Codes F24, F27, F28, F29)
If your Rexroth PPCR221 triggers a fault, follow these sequential steps to diagnose and clear the issue. 1. Verify the Power Supply
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.
If electronics check out but E40/E41 errors persist, the issue is likely hydraulic. Override the valve manually using the mechanical override pin (if equipped) to check if the spool moves freely. If it sticks, the valve body must be flushed or replaced due to oil contamination. Preventive Maintenance Tips rexroth ppcr221 fault codes full
These codes trigger during commissioning, system expansion, or hot-swapping hardware components.
The single most frequent fault code seen on a PPC-R22.1 controller is . This is a collective alarm mechanism. It indicates that the PPC itself is perfectly healthy, but one or more of the digital servo drives connected down the line has faulted out .
Solution: Flash the correct firmware build variant specified by the OEM or the Bosch Rexroth Product Portal. Commissioning and Component Integrity Faults (F21 to F23)
Check the drive status diagnostics in SynTop to identify the specific axis (driver) that is triggering the alarm. These codes trigger when the PPC controller experiences
Issues with the communication link between the PPC and the servo drives. This can be caused by faulty optical fibers, damaged connectors, or malfunctioning nodes.
Are you currently seeing a on your controller's display that you need to resolve? Debugging Rexroth PPC Fault Codes - Wake Industrial
The is a high-performance, multi-axis motion control processor platform designed for complex automation systems like the Rexroth VisualMotion and SYNAX environments. When a system malfunction occurs, the PPC-R22.1 controller’s built-in HMI display or diagnostic software quickly shows specific error codes. Identifying these codes immediately keeps down-time to a absolute minimum.
If you are experiencing a specific fault code not covered here, or if the problem persists after following the recommended steps, do not hesitate to reach out to Bosch Rexroth's technical support team. They have the specialized tools and expertise to resolve the most complex issues and get your production line moving again. Override the valve manually using the mechanical override
Too many drives connected for the controller's maximum capacity. F15 to F18 Soft Fault (Parameter Loss)
When the controller is powered on, it goes through a sequence of internal checks. If it hangs on a specific number, it indicates a hardware or firmware failure. Wake Industrial -01 to -2X
Triggered when a replacement hardware module or a different CF card is installed. The motherboard detects that the internal hardware identity profile differs from the stored validation string.
Issues with fieldbus (e.g., SERCOS, PROFIBUS) communication. Inspect fiber optic cables, connectors, and bus addresses. F98 Drive Fault
