Precharge
Precharge is the process of gradually increasing the DC-bus voltage. During this increase in DC-bus voltage, the DC-bus filter capacitors are
charged in a controlled manner. The precharge assembly can be part of the drive design or for some drives it can be externally provided and
controlled.
If an external voltage source is used to power the logic boards of the PowerFlex drives, take precautions to control the precharge sequence.
We recommend that you use the Precharge Enable digital input on the drive for common bus operation. The logic input can be coordinated
through a PLC or system-level control to sequence the precharge. The sequencing lets charge time constants for various horsepower drives
settle out before the precharge completes. Generally, a three second delay is acceptable after power has been applied. See Drives in
Common Bus Configurations Application Technique, publication DRIVES-AT002
, for precharge functionality on all Powerflex drive frame
types.
ATTENTION: An external source of power can be present. To avoid an electric shock hazard, verify that the AC power supply has been
removed before any maintenance is performed.
