Cause
• Via running AMA in VVC+ mode, the drive builds a mathematical model of the motor to optimize compati-
bility between drive and motor, and thus enhances the motor control performance.
• Some motors may be unable to run the complete version of the test. In that case, select
[2] Enable Reduced
AMA
in
parameter 1-29 Automatic Motor Adaptation (AMA)
.
• For best results, run the following procedure on a cold motor.
Procedure:
1. Set motor data in
parameter group 1-** Load and Motor
according to the motor nameplate.
2. Connect terminal 27 to terminal 12 (24 V voltage) or choose
[0] No operation
in
parameter 5-12 Terminal
27 Digital Input
.
3. Set
[1] Enable Complete AMA
or
[2] Enable Reduced AMA
for
parameter 1-29 Automatic Motor Adaptation
(AMA).
4. Press the [Hand On] key, the test runs automatically and the main display indicates when it is completed.
8.2 Automatic Motor Adaptation (AMA)
N O T I C E
[2] Coast inverse
is the default option for
parameter 5-12 Terminal 27 Digital Input
. If there is no 24 V supply to terminal 27,

does not start the motor. Connect terminal 12 to terminal 27.

(1) Stops the motor but does not remove power to the drive. (2) Resets the drive manually after a
fault has been cleared. (3) In alarm mode, the alarm is reset when the alarm condition is removed.
Puts the system in remote operational mode, in which the drive only respond to an external start
command via control terminals or bus communication.

and edit setup, only that setup number is shown (factory setting).
• For LCP 23, the setup number shows on the upper right corner in the status mode. For example, “1(2)” means
the active setup is "1" and the editing setup is "2".
