4.5 Auto-Tuning
Parameters such as stator resistance (R
s
), stator leakage inductance (sL ), flux
current (IF), rotor time constant (τ
r
) and stator self-inductance (Ls) are
indispensable for obtaining an excellent control performance in the vector control
and are automatically measured and set using auto-tuning function.
■ SV-iV5 features two types of Auto-tuning: 1) Rotational Auto Tuning
2) Standstill Auto Tuning
4.5.1 Motor and encoder parameter setting for auto-tuning
The Motor capacity, Basic speed, Rating voltage, Pole number, Efficiency, Rating
slip and Rating current on the nameplate of the motor and the pulse number of
encoder should be set before operation.
LCD Display Description

Enter the motor capacity.

Basic capacity is same with Inverter capacity

Enter directly in the PAR_08 after selecting
“User Define” if there is no Motor capacity.

Enter the motor capacity directly at PAR_08
incase that select “User Define” at PAR_07.

Set the pulse numbers per revolution of pulse
encoder coupled to the motor shaft.

Set the motor base speed.
Note) It is not rating current of name plate.
Base Speed = 120 X Base Frequency/
Pole number

Set the rated voltage of the motor.
(Voltage value on the name plate)

Set the number of poles of the motor.

Set the efficiency of the motor. If you cannot
find the efficiency in name plate, Do not set
the Efficiency.

Set the rated slip speed of the motor.
(Rated slip=synchronous speed
–rated speed)

Set the rated current of the motor.
