Intelligent Output Terminal Function

Frequency Arrival Signal [FA1]/[FA2]
Frequency Arrival [FA1] and [FA2] signals indicate when the output frequency accelerates or decelerates to
arrive at a constant frequency. Refer to the figure below.
Frequency Arrival [FA1](upper graph) turns on when the output frequency gets within 0.5Hz below or 1.5Hz
above the target constant frequency.
The timing is modified by a small 60ms delay. Note the active low nature of the signal, due to the
open collector output.
Frequency Arrival [FA2] (lower graph) uses thresholds for acceleration and deceleration to provide more
timing flexibility than [FA1].
Parameter C22 sets the arrival frequency threshold for acceleration, and parameter C23 sets the thresholds
for deceleration.
This signal also is active low and has a 60ms delay after the frequency thresholds are crossed.

Valid for inputs: C13, C14,C15, C22, C23
Required setting (none)
Notes:
• At the time of acceleration, an arrival signal at
a frequency between the set frequency
-0.5Hz to +1.5Hz is turned on.
• At the time of deceleration, an arrival signal at
a frequency between the set frequency
+0.5Hz to -1.5Hz is turned on.
• The delay time of the output signal is 60m
(nominal).
