H 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.
