------------------------------------------------ Test Run Procedure -------------------------------------------------
(1) Turn the power ON and check that the reference frequency
Hz is blinking on the LED
monitor.
(2) Set a low reference frequency such as 5 Hz, using
/ keys. (Check that the frequency is
blinking on the LED monitor.)
(3) Press the
key to start running the motor in the forward direction. (Check that the reference
frequency is displayed on the LED monitor.)
(4) To stop the motor, press the
key.
< Check points during a test run >
• Check that the motor is running in the forward direction.
• Check for smooth rotation without motor humming or excessive vibration.
• Check for smooth acceleration and deceleration.
When no abnormality is found, press the
key again to start driving the motor, then increase the
reference frequency using
/
keys. Check the above points again.
If any problem is found, modify the function code data again as described below.

4.2 Operation
After confirming that the inverter normally drives the motor in a test run, make mechanical
connections (connections to the machine system) and electrical connections (wiring and cabling),
and configure the necessary function codes properly before starting a production run.
Depending on the production run conditions, further adjustments can be required, such
as adjustments of torque boost (F09/A05), acceleration time (F07/E10), and deceleration
time (F08/E11).
4.2.1 Jogging Operation
This section provides the procedure for jogging the motor.
Making the inverter ready to jog with the steps below. The LED monitor should display
LQI
.
• Enter Running mode (see page 3-3).
• Press the + keys simultaneously. The LED monitor displays the jogging frequency for
approximately one second and then returns to
LQI
again.
• Function codes C20 and H54 specify the jogging frequency and acceleration/
deceleration time, respectively. Use these function codes exclusively for the
jogging operation with your needs.
• Using the input terminal command "Ready for jogging" JOG switches between the
normal operation state and ready-to-jog state.
• Switching between the normal operation state and read-to-jog state with the
+
keys is possible only when the inverter is stopped.
Jogging the motor.
Hold down the
key during which the motor continues jogging. To decelerate to stop the motor,
release the key.
Exiting the ready-to-jog state and returning to the normal operation state
Press the
+ keys simultaneously.
