Operation
No-load Operation
•Start the no-load motor (i.e., not connected to the mechanical system) using the Digital Operator.
* Before operating the Digital Operator, check that the FREQ adjuster is set to "MIN."
* Make sure that the LED indicator above the FREQ adjuster and the RUN command LED indicator
are lit.
Forward/Reverse Rotation via the Digital Operator
•By turning the FREQ adjuster, make sure that there is no vibration or abnormal sound from the
motor.
•Make sure that no errors have occurred in the Inverter during operation.
•Switch between forward and reverse with the operator rotation direction selection (F004).
Stopping the Motor
•After completing the no-load operation, press the STOP/RESET key. The motor will stop.
Actual Load Operation
•After checking the operation with the motor in the no-load status, connect the mechanical system
and operate with an actual load.
* Before operating the Digital Operator, check that the FREQ adjuster is set to "MIN."
Connecting the Mechanical System
•After confirming that the motor has stopped completely, connect the mechanical system.
•Be sure to tighten all the screws when fixing in the motor axis.
Operation via the Digital Operator
•Because a possible error may occur during operation, make sure that the STOP/RESET key on
the Digital Operator is easily accessible.
•Use the Digital Operator to operate the Inverter the same way as in no-load operation.
Checking the Operating Status
•After making sure that the operating direction is correct and that the Inverter is operating smoothly
at a slow speed, increase the frequency reference.
•By changing the frequency reference or the rotation direction, make sure that there is no vibration
or abnormal sound from the motor.
Make sure that the output current (output current monitor [d002]) is not excessive.
