3 Parameter Description
NB!
This parameter cannot be changed while the motor is running.
1-28 Motor Rotation Check
Option:
3
[0] * Off
[1] Enabled
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 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 par.1-28
motor phase cables should be interchanged. IMPORTANT:
Mains power must be removed before disconnecting motor phase cables.
1-29 Automatic Motor Adaptation (AMA)
Option:
[0] * Off
[1] Enable complete AMA
[2] Enable reduced AMA
Activate the AMA function by pressing [Hand on] after selecting [1] or [2]. See also the section
the display will read: "Press [OK] to finish AMA". After pressing the [OK] key the frequency converter is ready for operation.
Note:
• For the best adaptation of the frequency converter, run AMA on a cold motor
• AMA cannot be performed while the motor is running
NB!
It is important to set motor par. 1-2* Motor Data correctly, since these form part of the AMA algorithm. An AMA must be performed
to achieve optimum dynamic motor performance. It may take up to 10 min., depending on motor power rating.
NB!
Avoid generating external torque during AMA

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).
Motor Rotation Check is not active.
Motor Rotation Check is enabled. Once enabled, Display shows:
"Note! Motor may run in wrong direction".

Function:
The AMA function optimizes dynamic motor performance by automatically optimizing the advanced
