890: Why am I getting over-voltage trips?

1. The motor is getting overhauled by the process.
   1. Try and pinpoint it to one part of a move profile during operation, what part of the operation is different there?
2. The motor is driving a high-inertia load.
   1. Trying to slow down or speed up a high-inertia load at any rate can certainly cause the drive to trip on overvoltage. The load will want to keep spinning more than what the drive can produce to affect it.
3. The inverter is trying to decelerate or stop the motor too quickly.
   1. Adjust your decelerate time. When given more time to decelerate does the issue persists? If not then...
4. The application requires Dynamic Braking and does not have a Brake installed or....
5. There is a problem with the dynamic brake configuration.
   1. The Dynamic Brake is not enabled.
   2. The Dynamic Brake Overload is tripped.
   3. The Dynamic Brake Resistor is improperly sized.
   4. The Dynamic Brake is not properly set up in the configuration.
6. The application requires too much regeneration for a Dynamic Brake and requires an Active Front End (AFE) product.
