DC link overvoltage

What does 3210 mean?

The DC link voltage within the drive has exceeded its safe operating limit. This commonly occurs due to regenerative energy from the motor (e.g., during rapid deceleration) that cannot be dissipated, or an excessive input supply voltage. Prolonged overvoltage can damage the drive's internal components.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Increase deceleration ramp times if regenerative braking is causing the overvoltage.

2. 4

   Check for transient overvoltages on the supply line.
