DC Link Not Charged

Was bedeutet V4 ?

The V4 (Red) LED indicates that the DCLINK circuit inside the servo amplifier is charged to the specified voltage. If this LED does not light after the pre-charge sequence is finished, it suggests a problem with the DC link charging, potentially due to a short circuit or a defective charge current control resistor.

• DC link capacitor bank not adequately charged.
• Main power supply voltage is too low (e.g., P6-01).
• Faulty rectifier or charging circuit in the power module.
• Inrush current limiter failure.

1. 1

   Check the DC Link circuit for a short-circuit connection.

2. 2

   Replace the emergency stop unit, as the charge current control resistor may be defective within it.

3. 3

   Replace the servo amplifier.
