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 C21 sets the arrival frequency threshold for acceleration, and
parameter C22 sets the thresholds for deceleration. This signal also is active
low and has a 60ms delay after the frequency thresholds are crossed.
