Enter the name plate rated voltage.
Unit: volt
Value range: 120...500 V
Default setting: 230 or 460 V based on drive voltage
Adjustment value: in accordance with the motor name plate
Enter the no load phase to phase back EMF rms voltage at rated
speed (LF.11).
Unit: Vrms / at rated speed
Value range: 1...32000 V
Default setting : none
Adjustment value: in accordance with the motor name plate
Note: For LF.80 software versions =< v1.3 this parameter dis-
played volts peak at 1000 rpm. So the value was signi cantly
higher (i.e. greater than 1000V). When upgrading to the newer
software this value must be recalculated using the new meth-
od (Vrms at rated speed)
To convert the old value from V1.3 to the new value for V1.7 use
the following equation:
V1.7 value for LF.14 =
V1.3 value x LF.11
1000 x 1.414
This value is measured during auto tuning and will provide the
best value.

This parameter is not the efficiency of the motor but the ratio of
the magnetizing current to the total phase current of the motor.
Lower power factor values will increase the magnetizing cur-
rent to the motor and thus increase the  eld strength resulting in
tighter control of the motor. Higher values decrease the magne-
tizing current and the  eld strength.
Unit: 1
Value range: 0.50...1.00
Default setting: 0.90
Adjustment value: in accordance with the motor name plate
Note: If not known, a value of 0.9 is recommended for old high
slip motors and a value of 0.65 is recommended for gearless
induction motors.
For PM motors this parameter is not required and therefore is not
visible.
