C.1 Bridge, Capacitor Power Supply
The figure below shows the full-wave-bridge, capacitor-input
configuration most commonly used to power one or more 6415
drive modules. A single transformer provides isolation and
transforms the AC input voltage to a level that, when rectified,
provides the desired DC bus voltage. Fusing should be between
the rectifier and individual bus capacitors. This allows fuse size
to be based upon the current requirements of a single module to
provides the greatest protection. The capacitors must be
connected to the 6415 DC+ and DC- inputs using twisted pairs no
longer than three feet in length as shown to control winding
inductive effects. A regen clamp to absorb power transferred
from the motor to the 6415(s) is sometimes required. This
section provides selection guidelines for the power supply
components.
