Configuring the Field Supply
The FlexPak 3000 drive can be used with one of three types of field supplies:
• Standard Field Supply: Provides field control for the standard drive. All configuration
for the standard field supply is through hardware. There are no parameters related
to the standard field supply. This supply generates a fixed field voltage and does not
provide field economy.
• Optional Enhanced Field Supply: Provides electronic field trim, field economy, and
higher voltage field supplies than the standard field supply. The Enhanced Field
Supply kit must be installed to use this field supply.
• Field Current Regulated Supply: Replaces the standard or enhanced field excitation
supply with a current regulated supply. It provides user-adjustable field economy,
constant horsepower operation, and user-adjustable field loss. The Field Current
Regulator kit must be installed to use this field supply.
The Field Current Regulator kit is standard for drives that are 150 to 600 HP @
460 VAC or 75 to 300HP at 230 VAC. It is optional for lower HP drives.
The parameters you will configure for the field supply depend on the supply that is
installed in your drive. You can check
FLD CURRENT REGULATOR (P.586) to determine if
the Field Current Regulator kit is installed. If FLD CURRENT REGULATOR (P.586) reports
NOT INSTALLED , you have either the standard field supply, an Enhanced Field Supply
kit, or an incorrectly installed or failed Field Current Regulator kit. Check your drive
and installation notes to verify the type of field supply.
