083F0000 hex

Regeneration Processing Error

Omron · NJ/NX-series Machine Automation Controller

What does 083F0000 hex mean?

The regeneration processing was stopped to protect the Regeneration Resistor. This means the system halted regenerative braking to prevent damage to the resistor, potentially due to incorrect settings or overload conditions.

Common Causes

  • The regeneration processing is set inappropriately
  • The Regeneration Resistor is selected inappropriately
  • The Regeneration Resistor is used for continuous regenerative braking
  • The applied power supply voltage is higher than the specified value
  • Regeneration Resistor failure

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Verify regenerative braking parameters (e.g., resistor value, regeneration capacity, external resistor enable) in the associated servo drive against system design specifications.

  2. 2

    Inspect the wiring connections between the servo drive's regenerative terminals and the external braking resistor for integrity, looseness, corrosion, or damage.

  3. 3

    Measure the resistance value of the external braking resistor and compare it to its specified nominal value to confirm proper functionality.

  4. 4

    Monitor the application's operating conditions and the drive's regenerative load to assess if the braking resistor's capacity is sufficient for the duty cycle.
