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].
