Proportion of Motor Leakage Inductance (17-12)
(1) Parameter can only be set when using stator resistance auto tuning (17-00=2).
(2) Static non-rotational and rotational type auto tuning automatically measure the proportion of motor leakage
inductance so there for this parameter is not active in these tuning modes.
(3) Default value is 4%. It is required to perform an auto tune to save the adjusted value into parameter 02-33.
Motor Slip Frequency (17-13)
(1) Parameter can only be set when using stator resistance auto tuning (17-00=2).
(2) Static non-rotational and rotational type auto tuning automatically measure the proportion of motor leakage
inductance so there for this parameter is not active in these tuning modes.
(3) It is required to perform an auto tune to save the adjusted value into parameter 02-34.

Figure 4.3.98 Rated voltage and frequency settings
Step 1:
Select auto-tuning mode (17-00) and set motor rated output power (17-01) and motor rated current
(17-02) based on the motor nameplate data.
Step 2:
Set the motor rated voltage (17-03) to 440V based on the motor nameplate data.
Step 3:
Set the motor rated frequency (17-04) to 60Hz
Step 4:
Set the motor rated speed (17-05) and number of motor poles (17-06)
Step 5:
Set the motor no-load voltage (17-08) to 360V and value 20V lower than input voltage when using
torque control.
Step6:
Execute auto-tuning by setting auto-tuning parameter 17-10 to 1, next go to main screen and press
RUN to start auto-tuning. The value of motor rated frequency (17-04) is automatically set the base
frequency of motor 1. The inverter will automatically adjust the value of maximum output frequency of
motor 1(01-02) to the same value as base frequency of the motor 1 (01-12) if the maximum output
frequency set in parameter 01-02 is different from the base frequency of the motor 1 (01-12),
When the inverter input voltage (or frequency) is higher than the motor rated voltage (or frequency), set the motor
rated voltage (17-03) and the motor rated frequency (17-04) to the values of the motor nameplate.
