F3133

Error when checking interrupting circuits

Bosch Rexroth · IndraDrive MPx02

What does F3133 mean?

This non-fatal safety error indicates a detected problem during the internal monitoring or validation of safety-related interrupting circuits within the IndraDrive MPx02. These circuits are crucial for safely de-energizing motor power or safety outputs, and an error suggests their integrity is compromised.

Common Causes

  • Internal hardware fault within the IndraDrive MPx02's safety module, specifically in the power section interlock or output stages.
  • Failure of internal diagnostic routines to correctly verify the state of interrupting paths.
  • Firmware errors affecting the safety interrupt circuit monitoring.
  • External influences, such as severe voltage fluctuations or EMC disturbances, impacting sensitive internal circuitry.

Repair Steps & Checklist
