Rexroth Ppcr221 Fault Codes Full

The PPCR221 does not have a 7-segment display. Faults are communicated via:

A. RUN/ERR LED Patterns (Hardware & System Bus):

| LED State | Meaning | Likely Fault Code Category | | :--- | :--- | :--- | | Green RUN, Red ERR OFF | Normal operation | No fault | | Green OFF, Red ON | Hardware fault (internal) | CPU error, watchdog | | Green OFF, Red flashing (1Hz) | STOP state (no program) | Configuration missing | | Green ON, Red flashing (2Hz) | Bus communication error (Sercos, PROFIBUS, PROFINET) | Fieldbus fault | | Both flashing alternately | Firmware update / Bootloader mode | Recoverable via service tool | rexroth ppcr221 fault codes full

B. Fieldbus Specific Errors (Most Common):

C. The "User Faults" (80% of what you see): The PPCR221 runs CoDeSys 2.3. Any "Fault Code" shown on an HMI is almost certainly a custom variable (e.g., fault_code := 1234). You need the PLC project source code or a fault list exported from the program. The PPCR221 does not have a 7-segment display

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).

While the manual lists thousands, these are the most frequently encountered faults in the field: PROFINET: Faults are read via the engineering tool

| Code | Description | Typical Cause | | :--- | :--- | :--- | | E-0141 | Velocity controller limit | Hydraulic pump not keeping up, or valve disconnected. | | E-1010 | CNC Emergency Stop | Safety circuit open; wire broken on E-stop button. | | E-1600 | Position deviation | Mechanical jam or hydraulic cylinder leak causing drift. | | E-0020 | Watchdog triggered | PLC program crash or infinite loop in logic. | | E-1000 | Drive enable missing | Control voltage missing or safety relay tripped. |
