Rexroth Ppcr221 Fault Codes High Quality Full
| Fault Code | Description | Common Cause | Immediate Action | | :--- | :--- | :--- | :--- | | | DC Bus Undervoltage | Mains supply sag; blown input fuse; weak transformer. | Measure input L1-L2-L3. Should be within ±10% of rating. | | F302 | DC Bus Overvoltage | Excessive regenerative braking; decel time too short. | Increase decel time. Add a larger braking module. | | F305 | 24V Control Supply Fault | Internal power supply failure; overload on +24V terminals. | Remove all external 24V loads (sensors, relays). Test one by one. | | F310 | Phase Loss – Input Mains | Missing one phase on three-phase input. | Check upstream contactor, fuses, or circuit breaker. |
A: Yes. Send a control word bit (typically bit 7 of STW) via Profisafe or Modbus. But local reset is safer. rexroth ppcr221 fault codes full
| Fault Code | Description | Common Cause | Immediate Action | | :--- | :--- | :--- | :--- | | | Encoder Communication Error (EnDat) | Broken shield; faulty ribbon cable; noise interference. | Reseat encoder connector X8. Check for 5V supply between pins. | | F503 | Hall Sensor Invalid State | Three hall sensors giving an impossible pattern (e.g., 111 or 000). | Inspect hall sensor PCB inside motor. Replace if magnetized debris present. | | F510 | Resolver Mismatch | Motor feedback and drive resolver settings differ. | Compare P-0-0114 (Resolver poles) with actual motor. | | F512 | Speed Deviation Too High | Commanded speed vs. actual speed difference > threshold. | Mechanical binding; encoder coupling slipped. | | Fault Code | Description | Common Cause
