* 1. The factory setting depends on the Inverter capacity. The value for a 200 V Class Inverter of 0.4 kW is given.
* 2. The setting range is from 10% to 200% of the Inverter rated output current. The value for a 200 V Class Inverter for 0.4 kW is given.
* 3. The setting range depends on the Inverter capacity. The value for a 200 V Class Inverter of 0.4 kW is given.
„ Manual Motor Constant Setting Methods
The motor constants settings methods are given below. Make (enter) settings referring to the motor test report.
Motor Rated Voltage Setting
Set E2-01 to the rated current on the motor nameplate.
Motor Rated Slip Setting
Set E2-02 to the motor rated slip calculated from the number of rated rotations on the motor nameplate.
Amount of motor rated slip = Motor rated frequency (Hz) - No. of rated rotations (min
− 1
) x No. of motor
poles/120.
Motor No-Load Current Setting
Set E2-03 to the motor no-load current using the rated voltage and rated frequency. The motor no-load current
is not normally written on the motor nameplate. Consult the motor manufacturer.
Factory setting is the no-load current value for a standard Yaskawa 4-pole motor.
Number of Motor Poles Setting
E2-04 is displayed only when V/f control method with PG is selected. Set the number of motor poles (number
of poles) as written on the motor nameplate.
Motor Line-to-Line Resistance Setting
E2-05 is set automatically when performing motor line-to-line resistance autotuning. When you cannot per-
form tuning, consult the motor manufacturer for the line-to-line resistance value. Calculate the resistance from
the line-to-line resistance value in the motor test report using the following formula, and then make the setting
accordingly.

Motor Leak Inductance Setting
Set the amount of voltage drop due to motor leak inductance in E2-06 using the percentage over the motor
rated voltage. Make this setting when the high-speed motor inductance is small. If the inductance is not writ-
ten on the motor nameplate, consult the motor manufacturer.
Motor Iron Saturation Coefficients 1, 2 and 3 Settings
E2-07, E2-08 and E2-12 are set automatically using rotational autotuning.
E2-12
Motor iron sat-
uration coeffi-
cient 3
Sets the motor iron saturation
coefficient at 130% of magnetic
flux.
This constant is automatically set
during rotational autotuning.
