2.2.2 No-Load Operation

When the motor is in the no-load state (the load device is separated from the motor),
select the start mode and frequency setting as local (selected by using the MVC
‘Local/Remote’ ’control knob underneath the touch screen).
 After confirming the area in the vicinity of the machine is safe, operate the MVC locally
(not remotely). Please check for normal rotation of the motor, and that no faults are
displayed on the MVC.

When it is unable to operate locally due to site operation condition, please proceed
operation remotely after make sure E-stop loop or load machine safe device is normal.
2.2.3 Connection of Load Machine
 Check the connection of the motor shaft with load machine is secure.
2.2.4 Actual Load Operation
 Connect the motor to the equipment directly, and using the above-mentioned no-load
operation, operate in local or remote mode.
2.2.5 Local Operation

The same as no-load operation, please operate the machine in local mode.
 In order to prevent maloperation, always ensure the emergency stop operation is
working correctly.
 Test the frequency setting of 10Hz at low speed.
2.2.6 Operating State Confirmation
 Please confirm whether the rotational direction of the load machine is correct in a low
speed state, and whether the load machine operates smoothly after the frequency is
increased.
 After the frequency or the rotation direction is changed, please check whether there is
any vibration or abnormal sound from the machine.
 If a control fault occurs, such as vibration in the event of incorrect adjustment of the
settings, please make corrections with reference to the ‘Adjustment Guide’.
2.2.7 Confirm And Save Parameter Settings
Check the parameters that were changed at the trial run stage, and confirm the changed
parameters are saved (power down the controlling machine, then power on and check to confirm
the parameters have been saved correctly).
