The table below lists functions that can be assigned to terminals [Y1] and [30A/B/C].
To make the explanations simpler, the examples shown below are all written for the normal
logic (Active ON).
Inverter running -- RUN (Function code data = 0)
This output signal tells the external equipment that the inverter is running at a starting frequency
or higher. It comes ON when the output frequency exceeds the starting frequency, and it goes
OFF when it is less than the stop frequency. It is also OFF when the DC braking is in operation.
If this signal is assigned in negative logic (Active OFF), it can be used as a signal indicating
"Inverter being stopped."
Frequency arrival signal -- FAR (Function code data = 1)
This output signal comes ON when the difference between the output frequency and reference
frequency comes within the frequency arrival hysteresis width specified by E30. (Refer to the
description of E30.)
