Function code data = 8
Current limiter early warning -- CUR
This output signal comes ON when the current
command value exceeds the current limiter early
warning level specified by H19 and it is kept for the
timer period specified by H20.
This signal enables the converter to reduce the load
before the current limiter function is activated.

Restarting after momentary power failure -- U-RES
This output signal comes ON when the converter
detects a momentary power failure and shuts off its
output. After the power is restored and the DC link bus
voltage exceeds the undervoltage recovery level, this
signal goes OFF.
If such a long-time power failure that the control power
of the converter is lost occurs when the
U-RES is ON,
then restoring the power causes the converter to start in
the regular startup sequence with the
U-RES being
OFF.
Function code data = 10
In synchronization with source frequency -- SY-HZ
This output signal comes ON when the control
frequency inside the converter is synchronized with the
source frequency. It goes OFF upon detection of
out-of-synchronization, momentary power failure, or
frequency alarm.
This signal may go OFF when there is distortion or
dipping in the source voltage waveform due to adverse
power supply conditions.

E14 I/O function (Normally open/closed)
E14 configures contacts RUN, X1, Y1 to Y3, Y5 and
30RY individually as a "normally open" or "normally
closed" contact by software.
OP: Open
CL: Closed

E15 Converter overload early warning level
E15 specifies the overload early warning signal level to
apply before the overload protective function is
activated.
To issue an overload early warning, set E15 to less than
100%. When E15 = 100%, the early warning will be
issued at the same timing as the overload alarm.
Setting range: 50 to 105%
The overload early warning will be issued when
PRE-OL is assigned to any of control terminals [Y1]
through [Y3], [Y5], and [Y11] through [Y18] using any
of E02 to E13.
