Note: On older software versions this parameter displayed
volts peak at 1000 rpm. So the value was significantly higher
(i.e. greater than 1000V). When upgrading to the newer soft-
ware this value must be recalculated using the new method
(Vrms at rated speed)
To convert the old value from V1.3 to the new value for V1.6
use the following equation:
V1.6 value for LF.14 =
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
IM
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 field strength resulting in
tighter control of the motor. Higher values decrease the magne-
tizing current and the field strength.

Note: If not known, a value of 0. 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.
