• These frequency arrival signals will be output when the output frequency reaches the set level.
• In applications such as an elevator, use this signal for applying the brake. To release the brake, use
the overtorque (OTQ) signal (C021 to C025, C026 = 07).
• Set the Multi-function Output P1 to P5 Selection (C021 to C025) or Multi-function Relay Output (MA,
MB) Function Selection (C026) to 01 (FA1: Constant speed arrival signal), 02 (FA2: Set frequency
exceeded signal), 06 (FA3: Set-frequency only signal), 24 (FA4: Set frequency exceeded signal 2), or
25 (FA5: Set-frequency only signal 2) to allocate the desired signal.
• 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]
However, when the above parameter is set to 06 (FA3) or 25 (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]
