Operation Example Chapter 4-2

4-2-6 Actual Load Operation

• After checking the operation with the motor in no-load status, connect the

mechanical system and operate with an actual load.

Note Before operating the Digital Operator, check that the FREQ adjuster is set to

MIN.

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 accessible.

• 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 the 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 (IOUT or multi-function monitor U03) to ensure that the

output current is not becoming excessive.
