Trial Operation
Operation Using the Digital Operator
Press the Run Key. The motor will start to rotate. (forward rotation)
Press the Forward/Reverse Key. The motor will rotate in the reverse direction.
Press the Stop Key. The motor will stop. (The operation LED indicator will keep flashing until the motor

The frequency reference can be changed, even during operation. When this is done, the frequency
reference is changed as soon as the Enter Key is pressed to input the set values.
If the Jog Key is pressed when the Unit is stopped, it will rotate by the jog frequency (default setting: 6.0
Hz) only while the Key is being pressed.

After changing the frequency reference or the rotation direction, check that there is no vibration or
abnormal sound from the motor.
Check that no faults have occurred in the Inverter during operation.

4-2-7 Actual Load Operation

After checking the operation with the motor in no-load status, connect the mechanical system and
operate with an actual load.
Connecting the System
After confirming that the motor has stopped completely, connect the mechanical system.
Be sure to tighten all the screws when fixing the motor axis in the mechanical system.
Operation using the Digital Operator
In case a fault occurs during operation, make sure the Stop Key on the Digital Operator is easily acces-
sible.
Use the Digital Operator in the same way as no-load operation.
First set the frequency reference to a low speed of one tenth the normal operating speed.
Checking Operating Status
Having checked that the operating direction is correct and that the machine is operating smoothly at
slow speed, increase the frequency reference.
After changing the frequency reference or the rotation direction, check that there is no vibration or
abnormal sound from the motor. Check the monitor display to ensure that the U1-03 (output current) is
not becoming excessive.
