4.1.4 Test run
If the user set the function codes wrongly or without completely understanding this Instruction Manual and the
FRENIC-Eco User's 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 of the previous Section 4.1.1, "Inspection and preparation prior to powering on" to Section
4.1.3, "Preparation before running the motor for a test," and begin test-driving of the motor.
If any abnormality is found to the inverter or motor, immediately stop operation and determine the cause
referring to Chapter 6, "TROUBLESHOOTING."
--------------------------------------------------------- Procedure for Test Run ---------------------------------------------------------
(1) Turn the power ON and check that the LED monitor blinks while indicating the
*00
Hz frequency.
(2) Set the frequency to a low frequency such as 5 Hz, using
/ keys. (Check that frequency command
blinks on the LED monitor.)
(3) Press the
key to start running the motor in the forward direction. (Check that the frequency command is
displayed on the LED monitor correctly.)
(4) To stop the motor, press the
key.
<Check the following points>
• Check if the direction of rotation is forward.
• 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, and increase the frequency
command using
/
keys. Check the above points for the test-driving of the motor.

4.2 Operation
After confirming ordinary operation by performing a test run, make mechanical connections (connections of the
machine system) and electrical connections (wiring and cabling), and set the necessary parameters properly
before starting a production run.
Depending on the conditions of the production run, further adjustments can be required, such as
adjustments of torque boost (F09), acceleration time (F07), and deceleration time (F08). Make sure to
set relevant function codes properly.
