•This signal is also output during DC injection braking. Below is the time chart.
Frequency Arrival Signal
•This function outputs a signal when the output frequency has reached the set value. For elevating
machines, use this signal for applying the brake.

Description
The Inverter output frequency has reached the F001
set value.
The Inverter output frequency has fallen below the
F001 set value.
The Inverter output frequency has exceeded the C042
set value during acceleration.
The Inverter output frequency has fallen below the
C042 set value during acceleration.
Data Default setting
f on:1% of max. frequency
Set frequency
f off:2% of max. frequency
(Example) Max. frequency fmax = 120 (Hz)
Set frequency fset = 60 (Hz)
fon = 120 × 0.01 = 1.2(Hz)
foff = 120 × 0.02 = 2.4(Hz)
During acceleration:ON at 60 – 1.2 = 58.8 (Hz)
During deceleration:OFF at 60 – 2.4 = 57.6 (Hz)
