6-2-4 Setting Motor Parameters
The motor parameters other than the V/f pattern parameters are described below:
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.
Note 3. These settings are used as reference values for the motor slip compensation function.
Set the motor’s terminal resistance (phase to phase) in parameter E2-05. 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 varies with the Inverter’s capacity. The above setting applies to 200-V
class, 0.4-kW Inverters.
Note 2. Set
the motor iron core loss in 1-W increments. The default setting does not normally need to
be changed.
Note 3. The set value is used as the reference value for the torque compensation function.
