P75 Motor Rated Power Factor FUN 06
LED Display LCD Display
Range -0.01 – 1.00 (Default –0.92)
Description The Rated Power Factor parameter sets the motor power factor value that is used by the MX
2
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.

P76 Rated RMS Voltage FUN 05
LED Display LCD Display
Range 100, 110, 120, 200, 208, 220, 230, 240, 350, 380, 400, 415, 440, 460, 480, 500, 525, 575, 600, 660, 690, 800,
1000, 1140 (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.
See Also Meter (P79 / FUN 01) parameter on page 127.
Under Voltage Level (P39 / PFN 08) parameter on page 103.
Voltage Trip Time (P40 / PFN 09) parameter on page 104.
zNOTE: The rated RMS voltage must be set properly in order for the starter to operate properly.
