Prewarning supply module overload

What does E2086 mean?

The supply module is experiencing an elevated load, approaching its thermal capacity. This prewarning indicates that continuous operation at this level could lead to a shutdown of the supply module or the entire system.

• Continuous operation at or above the supply module's rated current.
• Motor or mechanical system experiencing excessive load or regeneration.
• Inadequate cooling for the supply module, possibly due to blocked vents, fan failure, or high ambient temperature.
• Incorrect configuration or undersized supply module for the application.

Click steps to track your progress.

1. 1

   Verify the total current draw from the supply module and ensure it is within its continuous operating limits.

2. 2

   Check the supply module's cooling fan for proper operation and ensure ventilation openings are clear of obstructions.

3. 3

   Measure the ambient temperature around the supply module and ensure it is within the specified operating range.

4. 4

   Review the application's duty cycle and peak loads; consider reducing load or increasing acceleration/deceleration times if possible.
