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:

ξFor 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].

ξFor each frequency arrival threshold, the output anticipates the threshold (turns ON early) by 1.5Hz.

ξThe output turns OFF as the output frequency moves away from the threshold, delayed by 0.5Hz.

ξThe delay time of the output signal is 60 ms (nominal).

ξThe 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 transistor.
