Open circuit detected on the line to proportional solenoid B.
The difference between the commanded position and actual position is too large for too long.
The supply voltage exceeds the safe operating limit (usually over 32V). rexroth ppcr221 fault codes full
Look for crimped wires, corroded pins, or loose terminal screws that trigger intermittent open circuits. 4. Monitor the Lag Error
Using the Rexroth service software allows you to view the active fault log and click "Clear Errors." Open circuit detected on the line to proportional solenoid B
Most fault codes on the PPCR221 require a specific action to clear:
The feedback sensor is reporting a value outside the expected physical window. ⚡ Group 3: Solenoid and Output Errors Look for crimped wires, corroded pins, or loose
Internal sensor supply or reference voltage is out of tolerance. 📈 Group 2: Input and Signal Errors
