Hardware Description
The PowerFlex DC drive contains a power structure that has an armature and
field supply. The armature supply consists of a three–phase, full wave rectified,
dual bridge, capable of two or four quadrant output. The field supply consists of
single phase, full wave rectified bridge. Also associated with the power structure
are incoming line protection devices and contactor and dynamic brake control
circuits.
Frame D drives may contain series B fan components. Verify that you are working
on a Frame D, series A or series B drive by checking the data nameplate label on
the lower right side of the drive. The frame size is printed just above the serial
number in the lower right corner of the label. The series letter is printed on the
upper right corner of the label.
