F8203

Safety technology configuration parameter invalid

Bosch Rexroth · IndraDrive MPx02

What does F8203 mean?

This fatal safety error indicates that a safety technology configuration parameter in the IndraDrive MPx02 is invalid or inconsistent. This means the drive's safety logic cannot be reliably established, rendering the safety functions inoperable and causing a system shutdown.

Common Causes

  • Corruption of safety configuration parameters due to power interruption or improper save/load operations.
  • Incompatible parameter values (e.g., exceeding limits, conflicting settings).
  • Mismatched safety configuration between the IndraDrive MPx02 and an external safety PLC.
  • Manual entry of incorrect or out-of-range safety parameter values.
  • Firmware incompatibility with the current safety parameter set.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Review all safety technology configuration parameters in the IndraDrive MPx02, comparing them against the machine's safety documentation and drive manual.

  2. 2

    Attempt to load a previously saved, validated safety parameter set that is known to be correct for the application.

  3. 3

    Verify that the firmware version of the IndraDrive MPx02 is compatible with the version of the safety parameters.

  4. 4

    If an external safety PLC is used, ensure its safety program and parameters match the drive's configuration.

  5. 5

    Perform a safety system re-commissioning, if necessary, meticulously verifying each parameter setting.
