Rockwell Automation 7000 PowerFlex Medium Voltage AC Drive (B Frame) - Classic Control - Manual (Page 200)

Commissioning 4-41
7000 “B” Frame 7000-UM150I-EN-P – June 2013
Three Phase Input / Single Phase Input
This configuration has two sources of control power:
• Three phase control power for fan operation and drive control
• Single-phase control power to operate the Interface, I/O and
additional auxiliaries.
Similar to the three-phase configuration, the input power for the fan
and control must be verified at the primary of FDS1. However, the
second source of control power must also be verified against the prints
at Circuit Breaker 1 (Labeled CB1 on the Electrical Schematics).
If the ratings match the designation on the electrical schematic, it is
acceptable to apply control power to the drive by closing CB1 and
FDS1. Take necessary measures to rectify the control power levels in
the event that they do not meet the design specifications.
Power Supply Tests
The variety of components installed within the PowerFlex 7000 “B”
Frame requires a versatile control distribution design. As a result
there are many power supplies incorporated within the drive design.
The following section describes how to verify that all power supplies
installed within the drive are functioning as designed.
Circuit Board Healthy Lights
Once all sources of control power have been verified and proven to
be within specified levels, close the low voltage input breaker (CB1)
and Fan Disconnect Switch (FDIS); doing so will apply control
power to the drive.
Observe the healthy lights on all drive control boards to ensure that
the unit has passed all power-up self-tests. The following table
identifies the LEDs that should be illuminated, assuming the drive
passes all self-tests and is in a ready state:
