DC Bus information

4.10.1 SE DC Bus levels
0V trip level
Braking level
Rated upper level (AC mains +10% x 1.4142)
Rated lower level (AC mains -10% x 1.4142)
*
UV reset level
UV trip level
Standard ramp voltage 2.08
* These are the absolute minimum DC voltages that the drive can be supplied with. If the drive is not supplied with at least
this voltage, it will not reset out of a UU trip at power up.
