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.
