Issue:   On an ATV312......M3X series drive, 200-240V input:  At what voltage on the DC bus does the braking transistor turn on and conduct power through the braking resistor?
 
Product Line:   ATV312
 
Environment:  ATV312......M3X
 
Cause:   DC bus voltage treshold for braking
 
Resolution:   
The braking transistor will turn on when the DC bus voltage reaches 379VDC.
