7.3 Testing Before System Start-up
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.
7.3.1 Motor Rotation
NOTICE
If the motor runs in the wrong direction, it can damage
equipment. Before running the unit, check the motor
rotation by briefly running the motor. The motor runs
briefly at either 5 Hz or the minimum frequency set in
parameter 4-12 Motor Speed Low Limit [Hz]
.
1.
Press [Hand On].
2.
Move the left cursor to the left of the decimal
point by using the left arrow key, and enter an
RPM that slowly rotates the motor.
3.
Press [OK].
4.
If the motor rotation is wrong, set
parameter 1-06 Clockwise Direction
to
[1] Inverse
.
7.3.2 Encoder Rotation
If encoder feedback is used, perform the following steps:
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.
In
parameter 16-57 Feedback [RPM]
, check that the
feedback is positive.
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 Feedback Direction
to
inverse the direction, or reverse the encoder cables.
Parameter 17-60 Feedback Direction
is only available with
the VLT
®
Encoder Input MCB 102 option.
7.4 System Start-up
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.
The procedure in this section requires user-wiring and
application programming to be completed. The following
procedure is recommended after application set-up is
completed.
1.
Press [Auto On].
2.
Apply an external run command.
Examples of external run commands are a switch,
key, or programmable logic controller (PLC).
3.
Adjust the speed reference throughout the speed
range.
4.
Ensure that the system is working as intended by
checking sound and vibration level of the motor.
5.
Remove the external run command.
