Chapter 4 Commissioning the Drive
Three-Phase Input / Single Phase Input
This configuration has one source of control power:
• Three-phase control power for fan operation which is also converted to
single-phase control power to operate the Interface, power supplies, 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 DS1.
If the ratings match the designation on the electrical schematic, it is acceptable to
apply control power to the drive by closing CB1 and DS1. 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 Disconnect Switch
(DIS); 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:
