Enable Auto Tune
Auto Tune function starts running.
NB!
To gain optimum tuning of frequency converter, run Auto Tune on a cold motor.
4.2.2. 1-3* Adv. Motor Data
Adjust advanced motor data using one of these methods:
1.
Run Auto Tune on cold motor. Frequency converter measures value from motor.
2.
Enter X
1
value manually. Obtain value from motor supplier.
3.
Use R
s
, X
1
, and X
2
default setting. Frequency converter establishes setting based on motor nameplate data.
NB!
These parameters cannot be changed while motor runs.
1-30 Stator Resistance (R
s
)
Range:
Function:
Depending on motor data
*
[Ohm]
Set stator resistance value.
1-33 Stator Leakage Reactance (X
1
)
Range:
Function:
Depending on motor data
*
[Ohm]
Set stator leakage reactance of motor.
1-35 Main Reactance (X
2
)
Range:
Function:
Depending on motor data
*
[Ohm]
Set motor main reactance.
4.2.3. 1-5* Load Independent Setting
This parameter group is for setting the load independent motor settings.
1-50 Motor Magnetization at Zero Speed
Range:
Function:
This parameter enables different thermal load on motor when running at low speed.
100 %
*
[ 0 - 300%]
Enter a percentage of rated magnetizing current. If setting is too low, motor shaft torque may be reduced.
1-52 Min. Speed Normal Magnetizing [Hz]
Range:
Function:
Use this parameter along with par. 1-50,
