E29
E30
Frequency arrival delay timer (FAR2)
Frequency arrival detection width (Detection width)
E30 specifies the detection level for the Frequency (speed) arrival signal “FAR”, Frequency (speed) arrival signal 2
“FAR2” and the Frequency (speed) arrival signal 3 “FAR3”.

assignment data
Operating condition 1
Operating condition 2
"FAR"
1
The signals come ON when the
difference between the output
frequency (estimated/actual speed)
and the reference frequency
(reference speed) comes within the
frequency arrival width specified by
E30.
FAR always goes OFF when the run
command is OFF or the reference
speed is “0.”
“FAR3”
72
When the run command is OFF, the
inverter regards the reference
speed as “0,” so FAR3 comes ON
as long as the output frequency
(estimated/ actual speed) is within
the range of “0 ± the frequency
arrival width specified by E30.”
“FAR2”
21
The signal comes ON when the
difference between the output
frequency (before torque and current
limiting) and the reference frequency
(reference speed) comes within the
frequency arrival width specified by
E30.
This signal always goes OFF when
the run command is OFF or the
reference speed is “0.”
The delay can be specified by E29.
"FARFDT"
87
“FAR” and “FDT” AND signals
• Data setting range: E30: 0.0 to 10.0 (Hz), E29: 0.01 to 10.00 (s)
The operation timings of each signal are as shown below.
