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.
