Frequency Arrival Signals
The Frequency Arrival group of outputs helps coordinate external systems with the current
velocity profile of the inverter. As the name implies, output [FA1] turns ON when the output
frequency arrives at the standard set frequency (parameter F001). Output [FA2] relies on
programmable accel/ decel thresholds for increased flexibility. For example, you can have
an output turn ON at one frequency during acceleration, and have it turn OFF at a different
frequency during deceleration. All transitions have hysteresis to avoid output chatter if the
output frequency is near one of the thresholds.

Notes:
 For each frequency arrival threshold, the output
anticipates the threshold (turns ON early) by 1%
of the maximum frequency.
 The output turns OFF as the output frequency
moves away from the threshold, delayed by 2%
of the maximum frequency.
 The example circuit for terminal [11] drives a
relay coil. Note the use of a diode to prevent the
negative going turn-off spike generated by the
coil from damaging the inverter's output
