When the motor operates normally, alarm output becomes OFF. When the protective
function operates, alarm output becomes ON. The upper controller being used by the
user detects this alarm and then stops motor operation command. If overload or
overcurrent occurs while the motor is ope rating, the drive detects it and cuts off
the motor's current. And alarm output is set to ON and also 'AlarmBlink' flash
so that the user can check abnormality type. The following table shows alarm type
according to flash count.
