To run AMA using the LCP
1.
By default parameter setting, connect terminals
12 and 27 before running AMA.
2.
Enter the
Main Menu
.
3.
Go to parameter group
1-** Load and Motor
.
4.
Press [OK].
5.
Set motor parameters using nameplate data for
parameter group
1-2* Motor Data
.
6.
Set motor cable length in
parameter 1-42 Motor
Cable Length
.
7.
Go to
parameter 1-29 Automatic Motor Adaptation
(AMA)
.
8.
Press [OK].
9.
Select
[1] Enable complete AMA
.
10.
Press [OK].
11.
The test runs automatically and indicates when it
is complete.
Depending on the power size, the AMA takes 3 to 10
minutes to complete.
NOTICE
The AMA function does not cause the motor to run and
it does not harm the motor.
5.5 Checking Motor Rotation
Before running the frequency converter, check the motor
rotation.
1.
Press [Hand On].
2.
Press [
▲
] for positive speed reference.
3.
Check that the speed displayed is positive.
4.
Verity that the wiring between the frequency
converter and the motor is correct.
5.
Verity that the motor running direction matches
the setting in
parameter 1-06 Clockwise Direction
.
•
When
parameter 1-06 Clockwise Direction
is set to
[0] Normal
(default clockwise):
a.
Verify that the motor turns
clockwise.
b.
Verify that the LCP direction
arrow is clockwise.
•
When
parameter 1-06 Clockwise Direction
is set to
[1] Inverse
(counterclockwise):
a.
Verify that the motor turns
counterclockwise.
b.
Verify that the LCP direction
arrow is counterclockwise.
5.6 Checking Encoder Rotation
Only check encoder rotation if encoder feedback is used.
1.
Select
[0] Open Loop
in
parameter 1-00 Configu-
ration Mode
.
2.
Select
[1] 24 V encoder
in
parameter 7-00 Speed
PID Feedback Source
.
3.
Press [Hand On].
4.
Press [
▲
] for positive speed reference
(
parameter 1-06 Clockwise Direction
at
[0] Normal
).
5.
Check in
parameter 16-57 Feedback [RPM]
that the
feedback is positive.
NOTICE
NEGATIVE FEEDBACK
If the feedback is negative, the encoder connection is
wrong. Use
parameter 5-71 Term 32/33 Encoder Direction
to inverse the direction, or reverse the encoder cables.
5.7 Local-control Test
1.
Press [Hand On] to provide a local start command
to the frequency converter.
2.
Accelerate the frequency converter by pressing
[
▲
] to full speed. Moving the cursor left of the
decimal point provides quicker input changes.
3.
Note any acceleration problems.
4.
Press [Off]. Note any deceleration problems.
If acceleration or deceleration problems occur, see
. See
for resetting the frequency converter after a
trip.
