4.2.60 Running signal (RUN)
While the inverter is operating, it outputs the running (RUN) signal via
an intelligent output terminal ([11] to [15]) or the alarm relay terminal.
To use this signal function, assign function "00" (RUN) to one of the intelligent output terminals [11] to [15] (C021 to
C025) and the alarm relay terminal (C026).
The inverter outputs the RUN signal even while operating the DC brake. The following figure shows a timing chart for
the signal output:

4.2.61 Frequency arrival signals (FA1, FA2, FA3, FA4, and FA5)
The inverter outputs a frequency-arrival signal when the inverter
output frequency reaches a set frequency.
When using the inverter for a lift, use the frequency-arrival signal
as a trigger to start braking. Use the over-torque signal as the trigger
to stop braking.
Assign the following functions to five of the intelligent output terminals [11] to
[15] (C021 to C025) and the alarm relay terminal (C026):
"01" (FA1: constant-speed reached), "02" (FA2: set frequency overreached), "06" (FA3: set frequency reached), "24"
(FA4: set frequency overreached 2), and "25" (FA5: set frequency reached 2)
The hysteresis of each frequency-arrival signal is as follows:
When the signal is on: ("set frequency" - "1% of maximum frequency") (Hz)
When the signal is off: ("set frequency" - "2% of maximum frequency") (Hz)
The signal hysteresis at acceleration with function "06" (FA3) or "25" (FA5) set is as follows:
When the signal is on: ("set frequency" - "1% of maximum frequency") (Hz)
When the signal is off: ("set frequency" + "2% of maximum frequency") (Hz)
The signal hysteresis at deceleration with function "06" (FA3) or "25" (FA5) set is as follows:
When the signal is on: ("set frequency" + "1% of maximum frequency") (Hz)
When the signal is off: ("set frequency" - "2% of maximum frequency") (Hz)
