and
1-35 Main Reactance
.
1-22 Motor Voltage (U_
m.n
)
Range:
Function:
230/400 V [50-999 V] Enter motor voltage from nameplate
data.
1-23 Motor Frequency (f_
m.n
)
Range:
Function:
50 Hz
*
[20-400 Hz] Enter motor frequency from nameplate
data.
1-24 Motor Current (I_
m.n
)
Range:
Function:
M-type dependent
*
[0.01-100.00 A] Enter motor current from
nameplate data.
1-25 Motor Nominal Speed (n_
m.n
)
Range:
Function:
M-type Dependent
*
[100-9999 RPM] Enter motor nominal
speed from nameplate
data.
1-29 Automatic Motor Tuning (AMT)
Option:
Function:
Use AMT to optimize motor performance.
NOTE
This parameter cannot be changed while
motor runs.
1.
Stop the frequency converter - make
sure motor is at standstill
2.
Choose
[2] Enable AMT
3.
Apply start signal
- Via LCP: Press [Hand On]
- Or in Remote On mode: Apply start
signal on terminal 18
[0]
*
Off
AMT function is disabled.
[2]
Enable
AMT
AMT function starts running.
NOTE
To gain optimum tuning of the frequency
converter, run AMT on a cold motor.
4.2.2 1-3* Adv. Motor Data
Adjust advanced motor data using one of these methods:
1.
Run AMT on cold motor. The 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. The frequency
converter establishes setting based on motor
nameplate data.
NOTE
These parameters cannot be changed while the motor
runs.

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.
