Checking Motor Rotation; Checking Encoder Rotation; Local-Control Test - Danfoss VLT Midi Drive FC 280 Operating Instructions Manual

Commissioning
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.
5 5
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 [
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.

] for positive speed reference.
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):

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 [
(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
▲
[
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
chapter 8.5 Troubleshooting. See chapter 8.2 Warning and
Alarm Types for resetting the frequency converter after a
trip.
a. Verify that the motor turns
counterclockwise.
b. Verify that the LCP direction
arrow is counterclockwise.
