Parameter Description
1-26 Motor Cont. Rated Torque
Range: Function:
parameter is valid for PM and non-
salient SPM motors only.
1-28 Motor Rotation Check
Option: Function:
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: "Please Note! Motor may run in wrong direction".
Pressing [OK], [Back] or [Cancel] will dismiss the message
and display a new message: "Press [Hand On] to start the
motor. Press [Cancel] to abort". Pressing [Hand On] starts
the motor at 5 Hz in the forward direction; 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 1-28 Motor Rotation Check. If
motor rotation direction is incorrect, two motor phase
cables should be interchanged.
WARNING
Line power must be removed before disconnecting motor
phase cables.
1-29 Automatic Motor Adaptation (AMA)
Option: Function:
The AMA function optimizes dynamic motor
performance by automatically optimizing the
advanced motor 1-30 Stator Resistance (Rs) to
1-35 Main Reactance (Xh)) while the motor is
stationary.

NOTICE!
1-29 Automatic Motor Adaptation (AMA) will not have effect
when 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 will
read: "Press [OK] to finish AMA". After pressing [OK] the
adjustable frequency drive is ready for operation.
NOTICE!
•
For the best adaptation of the adjustable
frequency drive, run AMA on a cold motor
•
AMA cannot be performed while the motor is
running
NOTICE!
Avoid generating external torque during AMA.
NOTICE!
If one of the settings in parameter group 1-2* Motor Data
is changed, 1-30 Stator Resistance (Rs) to 1-39 Motor Poles,
the advanced motor parameters, will return 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 AQUA Drive Design Guide, MG20NXYY.
3.3.5 1-3* Adv. Motor Data
Parameters for advanced motor data. The motor data in
1-30 Stator Resistance (Rs) to 1-39 Motor Poles must match
the relevant motor in order to run the motor optimally.
The default settings are figures based on common motor
parameter values from normal standard motors. If the
motor parameters are not set correctly, a malfunction of
the adjustable frequency drive system may occur. If the
motor data is not known, running an AMA (Automatic
Motor Adaptation) is recommended. See section:
Application Examples > Automatic Motor Adaptation in the
VLT AQUA Drive Design Guide, MG20N. The AMA sequence
will adjust all motor parameters except the moment of
inertia of the rotor and the iron loss resistance (1-36 Iron
Loss Resistance (Rfe)).
