3.7 Check Motor Rotation
Before running the adjustable frequency drive, check the
motor rotation.
1. Press [Hand On].
2. Press [
►
] for positive speed reference.
3. Check that the speed displayed is positive.
When
1-06 Clockwise Direction
is set to
[0] Normal
(default
clockwise):
4a. Verify that the motor turns clockwise.
5a. Verify that the LCP direction arrow is
clockwise.
When
1-06 Clockwise Direction
is set to
[1] Inverse
(counter-
clockwise):
4b. Verify that the motor turns counter-clockwise.
5b. Verify that the LCP direction arrow is counter-
clockwise.
3.8 Check Encoder Rotation
Check encoder rotation only if encoder feedback is used.
Check encoder rotation in default open-loop control.
1.
Verify that the encoder connection is according
to
Figure 3.7 Wiring Diagram
NOTE!
When using an encoder option, refer to the option manual.
2.
Enter the speed PID feedback source in
7-00 Speed PID Feedback Source
.
3.
Press [Hand On].
4.
Press [
►
] for positive speed reference
(
1-06 Clockwise Direction
at
[0] Normal
).
5.
Check in
16-57 Feedback [RPM]
that the feedback
is positive.
NOTE!
If the feedback is negative, the encoder connection is
wrong!
