| 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. | rexroth ppcr221 fault codes full
