• Normally, you perform offline auto-tuning to set motor parameters.
However, if the offline auto-tuning process is aborted, for example, when the inverter does not reach
50% of its rated current during auto-tuning, you need to set the motor parameters manually.
• To configure the motor parameters manually, set the 1st/2nd Motor Parameter Selection
(H002/H202) to 00 (Standard motor parameter).
To maximize the performance of vector control, adjust the parameter values according to your motor.
• Obtain your motor’s datasheet from the motor manufacturer and set each motor parameter.
The following values must be set as 50-Hz converted data for one phase in Y-connection.
• After setting each motor parameter, adjust the parameter values according to
6-1-4 Adjustments for
Sensorless Vector Control
on page 6-10.
• 1st/2nd Speed Response (H005/H205) are parameters to adjust the speed response of sensorless
vector control. Increase the set value to enhance the responsiveness and decrease it if motor hunting
occurs.

Motor Parameter Settings
Winding resistance
on primary side of motor (H020/H220) : Set the wiring resistance (in
Ω
) on the primary side of the
motor for one phase in Y-connection.
Winding resistance
on secondary side of motor (H021/H221): Set the wiring resistance (in
Ω
) on the secondary side of
the motor for one phase in Y-connection.
Motor leakage inductance (H022/H222) : Set the leakage inductance (in mH) of the motor for one
phase in Y-connection.
Motor no-load current (H023/H223)
: Set the no-load current of the motor, or set the current
value measured when the motor is in isolated no-load run
at 50 Hz.
Moment of inertia (H024/H224)
: Calculate the motor-shaft conversion of the moment of
inertia of the load machine, add the moment of inertia of
the motor to it, and set the sum.
