3 Contactor Basic Bypass with Disconnect Package (Style C) 3-7
Rockwell Automation Publication 22C-IN002E-EN-P - November 2010
Operating Modes
Drive Mode
For this mode to be active, the door-mounted selector switch needs to be in
the DRIVE position. The DIC and DOC are energized and the BC is
de-energized.
When the drive is in HAND configuration, the start command comes from
the integral keypad Start/Hand key. The speed reference come from the
Digital Increment and Decrement keys.
When the drive is in AUTO configuration, the start command is set for
two-wire control. The drive runs when there is a closed contact between
terminals 19-20 located inside the Option Cabinet and stops when the
contact is open. Parameter P038 [Speed Reference] determines the source of
the speed reference. The drive package ships with the speed reference
configured for Analog In1 which would be wired to signal terminals 13-14
located on the drive. Refer to the PowerFlex 400 User manual for
information on other control schemes.

the “Test” position. The DIC is energized and the DOC and BC are
de-energized.
Off Mode
For this mode to be active, the door-mounted selector switch needs to be in
the “Off” position. The DIC, DOC and BC are all de-energized. The
PowerFlex drive will not be powered and the motor will not run.
Bypass Mode
In the Bypass Mode the BC is energized and the DIC and DOC are
de-energized. The motor is powered by the AC line. The motor will
immediately be powered when the selector switch is in the “Bypass”
position unless the “Drive/Bypass Enable” relay, CR, is used and is not
picked up.
