Over-voltage of DC Link (ECM)

What does 6 mean?

The DC link voltage in the servo amplifier system has exceeded the upper threshold. This can be caused by excessive regenerative energy not being dissipated or an issue with the power supply.

1. 1

   Measure the DC link voltage at the servo amplifier.

2. 2

   Verify the proper operation of the regenerative discharge unit and its connections.

3. 3

   Check the input power supply voltage for overvoltage conditions.
