1-25 Motor Nominal Speed
Range: Function:
Size

*
[100 -
60000 RPM]
NOTICE
This parameter cannot be
adjusted while the motor is
running.
Enter the nominal motor speed value
from the motor nameplate data. The
data is used for calculating automatic
motor compensations.
1-26 Motor Cont. Rated Torque
Range: Function:
Size
related
*
[1 -
10000.0
Nm] Enter the value from the motor
nameplate data. The default value
corresponds to the nominal rated output.
This parameter is available when
parameter 1-10 Motor Construction is set
to [1] PM, non-salient SPM , that is the
parameter is valid for PM and non-salient
SPM motors only.
1-28 Motor Rotation Check
Option: Function:
WARNING
HIGH VOLTAGE
Frequency converters contain high voltage
when connected to AC mains input, DC
supply, or load sharing.
•
Remove mains power before
disconnecting motor phase cables.
NOTICE
Once the motor rotation check is enabled,
the display shows:
Note! Motor may run in
wrong direction .
Pressing [OK], [Back], or [Cancel] dismisses
the message and shows a new message:
Press [Hand On] to start the motor. Press
[Cancel] to abort
. Pressing [Hand On] starts
the motor at 5 Hz in forward direction and
the display shows:
Motor is running . Check
if motor rotation direction is correct. Press
[Off] to stop the motor. Pressing [Off] stops
the motor and resets
parameter 1-28 Motor
Rotation Check . If motor rotation direction
is incorrect, interchange 2 motor phase
cables.
Following installation and connection of the
motor, this function allows the correct motor
rotation direction to be verified. Enabling this
1-28 Motor Rotation Check
Option: Function:
function overrides any bus commands or digital
inputs, except external interlock and Safe Torque
Off (STO) (if included).
[0]
*
Off Motor rotation check is not active.
[1] Enabled Motor rotation check is enabled.
1-29 Automatic Motor Adaptation (AMA)
Option: Function:
The AMA function optimizes dynamic motor
performance by automatically optimizing the
advanced motor
parameter 1-30 Stator
Resistance (Rs) to parameter 1-35 Main
Reactance (Xh) ) while the motor is stationary.
[0]
*
Off No function.
[1] Enable
Complete
AMA Performs AMA of the stator resistance R
S
, the
rotor resistance R
r
, the stator leakage
reactance X
1
, the rotor leakage reactance X
2
,
and the main reactance X
h
.
[2] Enable
Reduced
AMA Performs a reduced AMA of the stator
resistance R
s
in the system only. Select this
option if an LC filter is used between the
frequency converter and the motor.
[3] Enable
Complete
AMA II Performs enhanced functionality AMA II of the
stator resistance R
S
, the rotor resistance R
r
, the
stator leakage reactance X
1
, the rotor leakage
reactance X
2
, and the main reactance X
h
. For
improved results, update
parameter 14-43 Motor Cosphi .
[4] Enable
Reduced
AMA II Performs a reduced AMA II of the stator
resistance R
s
in the system only. Select this
option if an LC filter is used between the
frequency converter and the motor.
NOTICE
Parameter 1-29 Automatic Motor Adaptation (AMA) has no
effect when parameter 1-10 Motor Construction = [1] PM,
non-salient SPM .
Activate the AMA function by pressing [Hand On] after
selecting
[1] Enable complete AMA or [2] Enable reduced
AMA . See also the chapter Automatic Motor Adaptation in
the design guide . After a normal sequence, the display
reads: Press [OK] to finish AMA . After pressing [OK], the
frequency converter is ready for operation.
