FA2 will be output when the output frequency exceeds the Arrival Frequency During Accelera-
tion/Deceleration 1 (CE-10/CE-11); F4 will be output when the output frequency exceeds the Arrival
Frequency During Acceleration/Deceleration 2 (CE-12/CE-13).
Assign the output terminal functions 003 [FA2] and 005 [FA4] exceeding set frequency signal to one of
[CC-01] to [CC-07] that corresponds to the output terminal and output the signals.
The signals [FA2] and [FA4] can be output to output terminal functions individually as the exceeding set
frequency output signal.
Precautions for Correct Use
• The operation of [FA2] can be set through [CE-10] and [CE-11].
• The operation of [FA4] can be set through [CE-12] and [CE-13].

(Operation example)
Maximum frequency: 60 Hz
When [CE-10] = [CE-11] = 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
