10 If required, reinstall the auxiliary panel cover or AC line
disconnect removed in steps 4a & 4b. Torque the (3) bus bar
fasteners to the values listed below.
Fastener Size Maximum Torque
1 / 4 " 7.46 N-m (66 lb.-in.)
3 / 8 " 26.66 N-m (236 lb.-in.)
Installation, Cont’d
(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. The J21 Jumper on the Regulator
Board must be set to the same setting as the Enhanced Field Supply.
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 stopped. 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] .
