Motor parameter
 If induction motor can be completely disconnected from the load, select 05-00(P.301)=1 run motor to measure,
then press or on keypad and inverter will automatically calculate following parameters:
05-07(P.308)~05-08(P.309)
 If induction motor cannot be completely separated from the load, select 05-00(P.301)=2 don’t run motor to
measure, then press or on keypad and inverter will automatically calculate following
parameters:05-07(P.308)~05-08(P.309)

Users can also calculate these two parameters according to motor nameplate, parameters motor nameplate used
are: rated voltage U, rated current
I
, rated frequency
f
and power factor

.

Calculation method of no-load excitation current and mutual inductance of the motor is as follows, where

L
is
leakage inductance of the motor.

Note: 1. When inverter is used with different size motor, please be sure to set parameters
05-01(P.302)~05-06(P.307)。Vector control relies heavily on motor parameters, so to obtain good control
performance, accurate parameters of the motor controlled must be set.
2. If one or more parameter values in 05-01(P.302)~05-08(P.309) have been manually modified, reset the
inverter to reload the new parameter values.
