Inverter DC Link Undervoltage

¿Qué significa 5 ?

This alarm indicates an undervoltage condition in the DC link of the Inverter (Servo Amplifier). This can stem from loose DC link connections or issues with the control printed-circuit board's seating. If multiple modules are affected, the Power Supply may be the root cause.

• Loose screws for the DC link connection cable (bar).
• DC link low voltage condition occurring in more than one module (potentially Power Supply related).
• Faceplate (control printed-circuit board) of the Servo Amplifier not fully seated.

1. 1

   Check that the screws for the DC link connection cable (bar) are tight.

2. 2

   If the alarm occurs in only one Servo Amplifier, ensure the faceplate (control printed-circuit board) of that Servo Amplifier is pushed in as far as it will go.

3. 3

   Replace the Servo Amplifier in which this alarm has occurred.
