Setting Reference Frequency
The default of inverter reference frequency is keypad VP potentiometer regulation.
Before trial operation, please confirm the setting frequency of F0-00, and set the
expected reference input frequency through VP potentiometer.
Starting the Inverter
1.
In function setting status, press
JOG
+/-
, inverter starts up as per setting value of F0-11(The
default is 5.00Hz), and motor runs as per the direction set presently, please monitoring if
it runs in a correct direction.
2.
Press
RUN
on the keypad or turn the start terminal on, the motor runs to the setting
frequency of F0-00 displayed.
3.
When reverse terminal is on, the motor reverses to setting frequency.
4.
Press
<
<
to adjust motor speed during running process (See 4.2.6 for reference.).
5.
Press
STOP
RESET
to enter ramp-to-stop status, the speed of motor decreases until the motor
stops.
Operation Status Monitoring
1. Change input frequency or rotation direction, and monitor if there is vibration or
unexpected noise with the motor or not.
2. Check if inverter runs stably.
5.2.4
On-Load Operation
After idling operation of motor is succeeded, please connect motor to the mechanical load for
a trial operation.
Connecting Motor to Mechanical Load
1.
After motor stops, turn off the power of inverter, and connect the motor to mechanical
load.
2.
Tighten up screw to locate the mechanical load onto the motor shaft.
Starting up the Inverter
1.
Start up the inverter in the same way as that in idling operation.
2.
Set the frequency about 1/10 of the normal running speed.
3.
Get ready for pressing
STOP
RESET
in case of anything unexpected.
Operation Status Monitoring
1.
Monitor that the motor runs in the correct direction.
2.
Increase frequency setting only after load mechanism is stable when running at a low
speed.
3.
Change the input frequency or rotation direction of motor, and monitor whether there is
vibration or unexpected noise with motor or not.
4.
Monitor the parameters of C0-12 or C0-13 in running, and confirm whether the output
current of the inverter is normal.
