Note
A warning signal output can be provided in advance by the multi-function output terminal before
the inverter overload protection function (IOLT) operates. When the overcurrent time reaches
60% of the allowed overcurrent (120%, 1 min; 140%, 5 sec), a warning signal output is provided
(signal output at 120%, 36 sec).
6.2.4 Speed Command Loss
When setting operation speed using an analog input at the terminal block, communication
options, or the keypad, speed command loss setting can be used to select the inverter
operation for situations when the speed command is lost due to the disconnection of signal
cables.
