1397 Enhanced Field Supply Card 9
Setup (3) drive parameters, Jumper 21 on the drive’s Regulator Board, and
the Enhanced Field Supply Card’s jumper wire must be set to
configure the Enhanced Field Supply Card.
P.050 — Nominal AC Freq
This parameter must be set to match the AC input line’s frequency.
P.273 — Fld Econ Delay
Some motor fields may not be able to withstand the power dissipated
under full field voltage with the motor stoped. Parameter
P.273 [Fld Econ Delay] allows a fixed reduction of field voltage to be set
for a user specified amount of time while the motor is stopped. When
restarted, the motor will be returned to the full field output voltage
level set by
P.272 [E-Fld Volts Adj] .
Installation
