Appears immediately after replacing a sub-component or control card.
If the fault cannot be cleared:
The hardware E-stop loop is open. Check safety relays, light curtains, and physical stop buttons across the line.
: He checked these first. They often appeared after swapping spare parts or during a messy debugging session, usually signaling a mismatch between the RAM on the motherboard and the CF card. Everything looked synced. F24, F27, and F28
An infinite reading indicates an (replace coil). rexroth ppcr221 fault codes full
The onboard battery for preserving parameters is weak or dead.
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
The PPC-R22.1 coordinates synchronized multi-axis movements via SERCOS, Profibus, or Profinet. Breakdowns in this network layer trigger communication faults.
The controller fails to initialize.
Solution: Inspect physical DIP switches or system address variables to guarantee uniquely mapped nodes.
The PPC-R22.1 controller has a diagnostic display on the front panel that shows the current status or a fault code.
Rexroth PPC-R22.1 controllers display diagnostic codes, often starting with F or E, to indicate faults within SYNAX200 motion control systems. Common issues include optical cable faults (F01-F06), parameter loss (F15-F18), or F98, which indicates a fault on a connected drive. Detailed information, including troubleshooting steps for specific codes and diagnostic categories, can be found via Wake Industrial . Debugging Rexroth PPC Fault Codes - Wake Industrial
Internal component degradation or severe external electromagnetic interference (EMI). : He checked these first
This error often resolves by powering off and allowing the controller to re-synchronize data with the new hardware. 3. Memory and Password Settings (F0024 - F0029) F0024, F0027, F0028: Memory Issues Cause: Internal memory exhaustion or corruption.
When encountering a fault code, follow these general steps:
