8-8 Frequency Arrival Signal (FA1 to
FA5)
These frequency arrival signals will be output when the output frequency reaches the set level.
Allocate output terminals 11 to 15 (CC-01 to CC-05) or relay output 16 AL (CC-06, CC-07) to 002 (FA1:
Constant speed arrival signal), 003 (FA2: Set frequency exceeded signal), 004 (FA3: Set frequency
only signal), 005 (FA4: Set frequency exceeded signal 2), 006 (FA5: Set frequency only signal 2).
Below is the hysteresis of the frequency arrival signal:
ON: Set frequency - 1% of maximum frequency [Hz]
OFF: Set frequency - 2% of maximum frequency [Hz]
When the above parameter is set to 04 (FA3) and 06 (FA5), the hysteresis during acceleration is:
ON: Set frequency - 1% of maximum frequency [Hz]
OFF: Set frequency - 2% of maximum frequency [Hz]
And the hysteresis during deceleration is:
ON: Set frequency - 1% of maximum frequency [Hz]
OFF: Set frequency - 2% of maximum frequency [Hz]
The signal will be output when the frequency has reached the enabled frequency command.
Assign the output terminal function 002 [FA1]constant-speed reaching output signal to one of [CC-01]
to [CC-07] that corresponds to the output terminal and output the signal.
Precautions for Correct Use
The signal [FA1] may not be output stably when the frequency command fluctuates because an
analog input command is used. In this case, the symptom may be alleviated by using the
ON/OFF delay function of the output terminal.

(Operation example)
Maximum frequency: 60 Hz
Set frequency: 50 Hz
• fon=60×0.01=0.6Hz
• foff=60×0.02=1.2Hz
• In acceleration: On at 50 - 0.6 = 49.4 Hz
• In deceleration: On at 50 - 1.2 = 48.8 Hz
