4.1.4 Test run
If the user configures the function codes wrongly without completely understanding this Instruction
Manual, the motor may rotate with a torque or at a speed not permitted for the machine.
Accident or injury may result.
Follow the descriptions given in Section 4.1.1 "Checking prior to powering on" to Section 4.1.3
"Preparation before a test," then begin the test run of the motor.
If any abnormality is found in the inverter or motor, immediately stop operation and investigate the
cause referring to Chapter 6 "TROUBLESHOOTING."
------------------------------------------------
Test Run Procedure
-------------------------------------------------
(1) Turn the power ON and check that the reference frequency
*00
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 may be required, such as
adjustments of torque boost (F09), acceleration time (F07, E10), and deceleration time
(F08, E11).
