balance of electrical power. It compares the motor charac-
teristics with the data entered in parameters 1-20 to 1-25.
NOTICE
If warnings or alarms occur, see chapter 6.5 List of
Warnings and Alarms
Some motors are unable to run the complete version of
the test. In that case, or if an output filter is connected
4 4
to the motor, select [2] Enable reduced AMA.
For best results, run this procedure on a cold motor.
1. Press [Main Menu].
2. Select 1-** Load and Motor and then press [OK].
3. Select 1-2* Motor Data and then press [OK].
4. Select parameter 1-29 Automatic Motor Adaptation
(AMA) and then press [OK].
5. Select [1] Enable complete AMA and then press
[OK].
6. Press [Hand On] and then [OK].
The test runs automatically and indicates when it
is complete.

4.5 Testing Before System Startup

WARNING
MOTOR START
Failure to ensure that the motor, system, and any
attached equipment are ready for start can result in
personal injury or equipment damage. Before start:
•
Ensure that equipment is safe to operate under
any condition.
•
Ensure that the motor, system, and any
attached equipment are ready for start.

4.5.1 Motor Rotation

NOTICE
If the motor runs in the wrong direction, it can damage
equipment. Before running the motor, check its direction
of rotation by briefly running the motor. Run the motor
at either 5 Hz or the minimum frequency set in
parameter 4-12 Motor Speed Low Limit [Hz] as follows:
1. Press [Hand On].
2. Move the cursor to the left of the decimal point
by using the left arrow key and then enter an
RPM value that causes the motor to rotate slowly.
3. Press [OK].
4. If the motor rotation is wrong, change
parameter 1-06 Clockwise Direction to [1] Inverse.

4.5.2 Encoder Rotation

Only check encoder rotation if encoder feedback is used.
For more information on the encoder option, refer to the
option manual.

NOTICE
NEGATIVE FEEDBACK
If the feedback is negative, the encoder connection is
wrong. Use either parameter 5-71 Term 32/33 Encoder
Direction or parameter 17-60 to inverse the direction, or
reverse the encoder cables. Parameter 17-60 Feedback
Direction is only available with the VLT
MCB 102 option.

4.5.3 Local Control Test

Perform the local control test as follows:
1.
2.
3.
4.
If acceleration or deceleration problems occur, see
chapter 6.6 Troubleshooting. To reset the drive system after
a trip, clear all faults and then manually reset the system.
For a list of warnings and alarms, see chapter 6.5 List of
Warnings and Alarms.

Select [0] Open loop in parameter 1-00 Configu-
ration Mode.
Select [1] 24 V encoder in parameter 7-00 Speed
PID Feedback Source.
Press [Hand On].
Press [►] for positive speed reference
(parameter 1-06 Clockwise Direction at [0] Normal).
Check in parameter 16-57 Feedback [RPM] that the
feedback is positive.
Press [Hand On] to provide a local start command
to the drive system.
Accelerate the unit by pressing [
speed is reached. Moving the cursor to the left of
the decimal point provides quicker input changes.
Note any acceleration problems.
Press [Off]. Note any deceleration problems.
