Note 1. The setting units for parameters E1-04, E1-06, and E1-09 can be changed.
Note 2. This function is specific to flux vector control.

Setting Motor Parameters
The motor parameters (function E2) will all be set automatically when auto-tuning is performed, so it
normally isn’t necessary to set them manually. Set these parameters manually if auto-tuning can’t be
completed properly. These parameters cannot be changed during operation.
Set the rated current (A) shown on the motor’s nameplate.

Note The setting range is 10% to 200% of the Inverter’s rated output current. The default setting de-
pends upon the type of Inverter. (The table shows the default setting for 200-V class, 0.4-kW In-
verters.)
Calculate the rated slip (E2-02) from the value shown on the motor’s nameplate with the following equa-
tion and set this value.
Rated slip = rated frequency (Hz) – rated speed (r/min)

number of poles/120
Set the no-load current (E2-03) at the rated voltage and rated frequency. Normally this value isn’t shown
on the motor’s nameplate, so it might be necessary to contact the motor manufacturer.

Note 1. The default setting depends upon the type of Inverter.
(The table shows the default settings for 200-V class, 0.4-kW Inverters.)
Note 2. The setting range is between 0.00 and 0.1 less than the Inverter’s rated current.
Set the number of poles (E2-04) shown on the motor’s nameplate.

Set the motor’s terminal resistance between U and V, V and W, or W and U.
Usually the nameplate of the motor does not provide the motor’s terminal resistance. Contact the motor
manufacturer for a test report on the motor’s terminal resistance to set the following values.
•
Type E insulation:
Motor’s terminal resistance (
Ω
) at 75
°
C x 0.92
•
Type B insulation:
Motor’s terminal resistance (
