1-28 Motor Rotation Check
Option:
Following installation and connection of the motor,
this function allows the correct motor rotation
direction to be verified. Enabling this function
overrides any bus commands or digital inputs,
except External Interlock and Safe Stop (if included).
[0] Off Motor Rotation Check is not active.
[1] Enabled Motor Rotation Check is enabled.
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 displays 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.
WARNING
Remove mains power before disconnecting motor phase
cables.

Function:
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, i.e. the parameter is valid for PM and
nonsalient SPM motors only.
Function:
Function:
The AMA function optimises dynamic motor
performance by automatically optimising the
advanced motor parameter 1-30 Stator
Resistance (Rs) to parameter 1-35 Main
Reactance (Xh)) while the motor is stationary.

1-29 Automatic Motor Adaptation (AMA)
Option:
NOTICE
Parameter 1-29 Automatic Motor Adaptation (AMA) does
not have 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 item 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.

NOTICE
Avoid generating external torque during AMA.
NOTICE
If one of the settings in parameter group 1-2* Motor
Data is changed, parameter 1-30 Stator Resistance (Rs) to
parameter 1-39 Motor Poles, the advanced motor
parameters, returns to default setting.
This parameter cannot be adjusted while the motor is
running.
NOTICE
Full AMA should be run without filter only while reduced
AMA should be run with filter.
See section: Application Examples > Automatic Motor
Adaptation in the VLT
3.3.5 1-3* Adv. Motor Data
Parameters for advanced motor data. The motor data in
parameter 1-30 Stator Resistance (Rs) to
, the
S
parameter 1-39 Motor Poles must match the relevant motor
to run the motor optimally. The default settings are figures
and the

based on common motor parameter values from normal
standard motors. If the motor parameters are not set
correctly, a malfunction of the frequency converter system
may occur. If the motor data is not known, running an
AMA (Automatic Motor Adaptation) is recommended. See
Function:
option if an LC filter is used between the
frequency converter and the motor.
For the best adaptation of the frequency
converter, run AMA on a cold motor
AMA cannot be performed while the motor is
running
