Undervoltage

What does 4631 mean?

An undervoltage condition has been detected or reported in the drive or terminal. This means the supply voltage to the component has dropped below its minimum operational threshold. Undervoltage can cause erratic drive behavior, unstable control, or complete power loss, potentially damaging sensitive electronics if power fluctuates significantly.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Verify the capacity of the power supply unit is adequate for the connected load.

2. 4

   Monitor the supply voltage for transient drops or sags during operation.
