Enhanced Field Supply
The Enhanced Field Supply (Fig. 4.5) allows adjustment of the field
voltage through hardware jumper settings and parameter adjustment.
Prior to applying the Enhanced Field Supply output to the DC
motor’s field windings, the output voltage must be adjusted so that it
doesn’t exceed the rated motor field voltage. This procedure is
described in the Enhanced Field Supply Kit Installation manual,
Publication 1397-5.12.

ATTENTION: It is imperative that the Drive NOT
BE STARTED with the field windings in the
un-powered condition. Failure to follow these
procedures may result in a machine malfunction and/or
personal injury.
The output voltage and current of both the enhanced
field supply and the regulated field supply are
determined by the values contained in set-up
parameters.
