Loaded Operation
Connect the machine to the motor and then start operation as described for no-load operation (i.e., from the
Digital Operator or by using control circuit terminal signals).
Connecting the Load
•
After confirming that the motor has stopped completely, connect the mechanical system.
•
Be sure to tighten all the screws when securing the motor shaft to the mechanical system.
Operation using the Digital Operator
•
Use the Digital Operator to start operation in LOCAL mode in the same way as in no-load operation.
•
If fault occurs during operation, make sure the STOP Key on the Digital Operator is easily accessible.
•
At 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 oscillation or abnor-
mal sound from the motor. Check the monitor display to ensure that U1-03 (Output Current) is not too high.
•
Refer to Adjustment Suggestions on page 4-17 if hunting, vibration, or other problems originating in the
control system occur.
