Chap. 9 FUNCTION CODES
Alarm output (for any alarm) -- ALM
(Function code data = 99)
This output signal comes ON if any of the protective functions is activated and the inverter
enters Alarm mode.
E30 Frequency Arrival (Hysteresis width for FAR)
E30 specifies the detection level (hysteresis width) for FAR ("Frequency arrival signal").
The moment the output frequency reaches the zone defined by "Reference frequency ±
Hysteresis width specified by E30," the FAR comes ON.
The operation timings of signals are shown in the graph below.
E31 Frequency Detection (Detection level for FDT)
E32 Frequency Detection (Hysteresis width for FDT)
When the output frequency exceeds the frequency detection level specified by E31, the FDT
signal ("Frequency detected") comes ON; when it drops below the "Frequency detection level
minus Hysteresis width specified by E32," it goes OFF.
You need to assign the FDT (function code data = 2) to one of digital output terminals.
- Data setting range: 0.0 to 400.0 (Hz)
