Control Power Transformer (CPT) (“B” Frame only)
A control power transformer is supplied only in certain drive configurations. If
there is no control transformer supplied in the drive being commissioned, please
disregard the following information on setting the control voltage output level.
Measure the control voltage level at the secondary of the control power
transformer located in the DC link low voltage cabinet of the drive. Ensure that
the output of the transformer matches the specification on the electrical
schematics.
You can adjust the value of the output by changing the taps on the control
transformer. Disconnect the power at the disconnect switch prior to attempting
to change the control transformer tap setting.
AC/DC Converter (PS1)
Every PowerFlex 7000 “A” or “B” Frame drive has at least one AC/DC power
supply. As the number of devices increases, or to provide a redundant power
supply, the number of installed AC/DC power supplies may increase. The
electrical schematics provided by Rockwell Automation identify the number of
AC/DC power supplies in the drive being commissioned.
Ensure the output of the AC/DC power supply is 56V DC. To make
adjustments, see Publicat
