How can resolve problem 3210 DC link overvoltage Fault in ABB ACS380 Drive ?
Cause : Excessive intermediate circuit DC voltage.
1. Check that overvoltage control is on (parameter 30.30 Overvoltage control).
2. Check that the supply voltage matches the nominal input voltage of the drive.
3. Check the supply line for static or transient overvoltage.
4. Check brake chopper and resistor (if present).
5. Check deceleration time.Use coast-to-stop function (if applicable).
6. Retrofit drive with brake chopper and brake resistor.
Cause : Excessive intermediate circuit DC voltage.
If your Application has DBR(Braking Resistor Installed) and also has Inertia:
1) The drive (ACS 380) often trips with 3210 Fault, make sure that the overvoltage control (parameter 30.30) is not activated when using a braking resistor, as this could damage your drive.
2) Ensure that you have properly configured the Brake Chopper Parameters in Parameter 43.
3) Check the supply lines for any overvoltage and configure the drive accordingly in Parameter 95 HW configuration.
4) Customize the drive with an adaptive brake resistor and its Pmax capacity.
