Rexroth — Ppcr221 Fault Codes Full !exclusive!
Various power-on initialization states. If the controller remains in this state, it indicates a hardware initialization failure, often requiring board replacement. Optical Cable Communication Errors (F01 - F06)
Warnings (The system may continue operating, but attention is required).
The Rexroth PPCR221 fault codes can be broadly classified into the following categories:
The PPC-R22.1 coordinates synchronized multi-axis movements via SERCOS, Profibus, or Profinet. Breakdowns in this network layer trigger communication faults. rexroth ppcr221 fault codes full
Remedy : Replace the battery located behind the card access plate while control power remains to avoid absolute system variable wipeout. E240: Axis Lag Warning
An infinite reading indicates an (replace coil).
| | Description | Possible Causes | | --- | --- | --- | | PPCR221-01 | Motor not enabled | Motor not powered, motor enable signal not present | | PPCR221-02 | Motor overcurrent | Motor current exceeds maximum limit, motor winding fault | | PPCR221-03 | Motor undercurrent | Motor current below minimum limit, motor load too light | | PPCR221-04 | Motor temperature high | Motor temperature exceeds maximum limit, cooling system fault | | PPCR221-05 | Motor temperature low | Motor temperature below minimum limit, motor not warmed up | | PPCR221-06 | Position error | Incorrect position feedback, position sensor fault | | PPCR221-07 | Velocity error | Incorrect velocity feedback, velocity sensor fault | | PPCR221-08 | Acceleration error | Incorrect acceleration feedback, acceleration sensor fault | | PPCR221-09 | Communication error | Communication link fault, controller not responding | | PPCR221-10 | Power supply error | Power supply voltage out of range, power supply fault | Various power-on initialization states
When the control voltage is first applied, the PPC-R22.1 runs internal hardware checks. If it halts on one of these codes without reaching standard application execution, use this breakdown: Error / State Display Technical Meaning Diagnostic & Repair Actions CPU Self-Test & Internal Memory Verification
The system continues operating, but a parameter is near its limit.
Review the VisualMotion 11 configuration software to ensure all drive addresses (S-0-0002) are unique and within the system limits. Soft Fault Errors (F15 - F18) F15/F16: Software configuration mismatch. F17/F18: Fatal memory error. The Rexroth PPCR221 fault codes can be broadly
Meaning: The card lost communication with the master PLC via the bus network.
Since the PPC-R22.1 often manages drives via an optical fiber ring (SERCOS), communication errors are common. F01 to F06
If you see this after a power outage, the drive’s battery-backed RAM may have failed. You must rewrite parameters manually.
The PPC-R22.1 communicates via the or Rexroth VCP software interface. The fault codes are typically displayed in a standardized format: Error Code: E-xxxx or F-xxxx followed by a timestamp and a brief textual description.
The Rexroth PPCR221 is a high-performance proportional valve amplifier card used extensively in industrial hydraulic systems. When system anomalies occur, the card generates specific fault codes via its LED display or communication interface to protect hardware and simplify diagnostics.
