H37 [Load inertia
rate]
0/2 Select one of the following according to
motor inertia.
0 X 10-6
0 Less than 10 times that of motor
inertia
1 About 10 times that of motor
inertia
2 More than 10 times that of motor
inertia
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.

H40 [Control mode
select]
0/3 0 {Volts/frequency Control} 0 X 9-15
1 {Slip compensation control} 10-6
2 {PID Feedback control} 10-8
3 {Sensorless vector control} 10-11
H41 [Auto tuning] 0/1 If this parameter is set to 1, it
automatically measures parameters of the
H42 and H43.
0 X 10-
10
H42 [Stator
resistance
(Rs)]
0/5.0[
Ω
] This is the value of the motor stator
resistance.
- X
H44 [Leakage
inductance
(L
σ
)]
0/300.0
[mH]
This is leakage inductance of the stator
and rotor of the motor.

H46 Sensorless I
gain
I gain for Sensorless control 100 O
H50 [PID
Feedback
select]
0/1 0 Terminal I input (0 ~ 20 mA) 0 X 10-8
1 Terminal V1 input (0 ~ 10 V)
1) : Set H40 to 2 (PID control) or 3(Sensorless vector control) to display these parameters.
