Frequency Arrival Signals
Frequency Arrival
The
current velocity profile of the inverter. As the name implies, output [FA1] turns ON
when the output
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 most applications you will need to use only
one type of frequency arrival outputs (see
examples). However, it is possible assign both
output terminals to output functions [FA1] and
[FA2]
 For each frequency arrival threshold, the output
anticipates the threshold (turns ON early) by
1.5Hz
 The output turns OFF as the output frequency
moves away from the threshold, delayed by
0.5Hz
 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
