Undervoltage Error

¿Qué significa F226 ?

The drive controller monitors the DC bus voltage. If the DC bus voltage falls below a predefined minimal threshold, the drive independently shuts down, triggering the configured error reaction. This protects the drive from operation with insufficient power.

• The power source has been interrupted without first switching off the drive enable (RF) signal.
• Disturbance or sag in the main power supply.

1. 1

   Verify the logic and sequence of operations for the drive enable (RF) signal within the connected control system, ensuring it is removed before the power source is interrupted.

2. 2

   Check the main power supply voltage to the drive controller for stability and correct levels.

3. 3

   Measure the DC bus voltage during operation to identify any sags or interruptions.

4. 4

   Ensure the control enable signal is removed to clear the error.
