Note 1. For the input level, select whether you want a fault to be detected when the input signal is ON
(normally open input) or OFF (normally closed input).
Note 2. For the detection method, select whether you want faults to be detected any time that the Inverter is on or only during operation.
Note 3. For the operation selection, select the processing method that you want to be performed
when a fault has been detected.
Decelerate to stop: A fault is output and the output stopped in the selected deceleration time.
Coast to stop: A fault is output and the Inverter output is cut off.
Emergency stop: A fault is output and the output stopped in the fast-stop time (C1-09).
Continue operation: An alarm is output and operation continues.
When an alarm is going to be output externally, be sure to set one of the multi-function outputs
(H2) to alarm (Minor Fault, setting 10).
• An external fault setting cannot be set in more than one multi-function input.
