• When the output frequency is within the range of ± Frequency Arrival Detection Width (FAR1/FAR2/
FAR3/FDT3/FDT4) (3005Hex-1FHex) centering around the frequency reference, ON is output, and
when it is outside the range, this signal turns OFF
.
• During free-run or when the set frequency is less than the stop frequency, the RUN command turns
OFF, and turns OFF during a deceleration stop.
• The figure below shows an example of changing the frequency reference from frequency reference
(1) to frequency reference (2).

Alarm Signal (AL)
• The inverter detects an overcurrent, overvoltage, or some other abnormality, and outputs an alarm
signal (AL).
• The alarm signal is the default data of Output T
erminal [ROA, ROB] Function Selection
(3005Hex-1CHex).
• A trip state can be canceled by resetting the inverter, by which the alarm signal is also turned OFF.
• For details on a reset, refer to 6-8-1 Reset Function on page 6-43.

0 Hz Detection Signal (ZS)
• This signal is output when the output frequency of the inverter falls below the 0Hz Detection Output
Detection Level (ZS) (301FHex-64Hex).
