FUN:Rated PF
06 -0.92
Range -0.01 to 1.00 (Default –0.92)
Description The Rated Power Factor parameter sets the motor power factor value that is used by the MX starter
for TruTorque and Power control calculations and metering calculations.
If TruTorque or Power acceleration and/or deceleration control is used, it is very important to
properly set this parameter to the motor’s full load rated power factor (usually available on the motor
nameplate or from the motor manufacturer). For a typical induction motor, this value is between 0.80
and 0.95.
If the motor rated Power Factor is not available from either the motor nameplate or the motor
manufacturer, the value can be obtained by viewing the power factor meter.
With the motor running at full name plate current, view the power factor meter either by setting the
LED display’s Meter parameter to PF, or by pressing the up arrow key until the Motor PF meter is
displayed using the LCD display.
The meter value can be entered into the Rated Power Factor parameter.

11.50K, 12.00K, 12.47K, 13.20K, 13.80K (Default 480)
Description The Rated Voltage parameter sets the line voltage that is used when the starter performs Over and
Under line voltage calculations. This value is the supply voltage, NOT the motor utilization voltage.
When applied to medium voltage, (2200 and above) the voltage must be set correctly for the starter to
function properly.
