P.272 E-Fld Volts Adj

Parameter

P.272 [E-Fld Volts Adj]

is used to match the drive’s rated field

voltage to different DC motor field voltages. A field voltage below the
motor’s rated value can operate the motor above rated base speed with
reduced torque. A voltage above the motor’s rated base speed however,
could also result in armature overvoltage and overheating of the motor’s
field windings.

Shown below and on the following page is the range of output motor field
voltages available using the Enhanced Field Supply Card. With the
Enhanced Field Supply Card, output voltage to the motor field is set equal
to the AC input line voltage times a line multiplier.

Where:

The Line Multiplier = The Motor Nameplate Field Voltage

AC Line Input Voltage

The following line multipliers correspond to an Enhanced Field Supply
jumper setting of either A-C or B-C. The shaded values shown
correspond to settings for parameter

P.272 [E-Fld Volts Adj]

as explained in the

example on the following page. Jumper J21 on the Drive’s Regulator
Board must then be set to match the calculated A-C or B-C range.
