Select one of the following according to
motor inertia.
0 Less than 10 times that of motor
inertia
1 About 10 times that of motor
inertia
H37 [Load inertia
rate]
0/2
2 More than 10 times that of motor
inertia
0 X 10-6
H39 [Carrier
frequency
select]
1/15
[kHz]
This parameter affects the audible
sound of the motor, noise emission from
the inverter, inverter temp, and leakage
current. If the value is set higher, the
inverter sound is quieter but the noise from
the inverter and leakage current will
become greater.

H41 [Auto tuning] 0/1 If this parameter is set to 1, it
automatically measures parameters of the

0/5.0[Ω]
This is the value of the motor stator
resistance.

This is leakage inductance of the stator
and rotor of the motor.
