Issue:
DC bus level at which the Brake resistor engages for the ATV312 drives

Product line:
ATV312, Altivar 312

Environment:
all

Cause:
n/a

Resolution:
The internal transistor will output to a Brake resistor at the following voltage levels:

For 200-240V drives, the DC bus level is 379V
For 380-480V drives, the DC bus level is 792V
For 575V drives, the DC bus level is 948V
