Description
7
Motor overload pre-
warning
The AC drive determines whether the motor load exceeds the overload
pre-warning threshold according to the overload pre-warning coefficient
(F9-02) before performing the protection action. The terminal outputs an
"active" signal when the overload pre-warning threshold is exceeded.
8
AC drive overload pre-
warning
The terminal outputs an "active" signal 10s before the AC drive performs
overload protection.
9
Motor over-temperature
pre-warning
The terminal outputs an "active" signal when the motor temperature
reaches the threshold defined by F9-58, F9-60, or F9-62 (motor
overtemperature pre-warning threshold).
10
AC drive load loss output The terminal outputs an "active" signal when load loss occurs.
11
Undervoltage state output
The terminal outputs an "active" signal when undervoltage occurs on
the AC drive.
12
Output overcurrent
The DO/RO terminal outputs an "active" signal when the output current
of the AC drive remains higher than F8-40 (output overcurrent threshold)
for longer than F8-41 (output overcurrent detection delay).
13
Frequency-level detection
FDT1 output
When the running frequency is higher than the detected value, the DO/
RO terminal outputs an "active" signal. When the running frequency is
lower than the result of the detected value minus the FDT hysteresis
value, the "active" signal is canceled. For details, see the description of
F8-22 and F8-23.
14
Frequency-level detection
FDT2 output
When the running frequency is higher than the detected value, the DO/
RO terminal outputs an "active" signal. When the running frequency is
lower than the result of the detected value minus the FDT hysteresis
value, the "active" signal is canceled. For details, see the description of
F8-24 and F8-25.
15
Frequency reach
The DO/RO terminal outputs an "active" signal when the running
frequency of the AC drive is within a certain range (target frequency
±setpoint of F8-26).
16
Frequency 1 reach output
The DO/RO terminal outputs an "active" signal when the running
frequency of the AC drive is within the frequency detection range of F8-
27 (detection value 1 for frequency reach). The frequency detection
range is as follows: (F8-27–F8-28) to (F8-27+F8-28).
17
Frequency 2 reach output
The DO/RO terminal outputs an "active" signal when the running
frequency of the AC drive is within the frequency detection range of F8-
30 (detection value 2 for frequency reach). The frequency detection
range is as follows: (F8-30–F8-31) to (F8-30+F8-31).
18
Frequency upper limit
reach
The terminal outputs an "active" signal when the running frequency
reaches the frequency upper limit (F0-12).
19
Frequency lower limit
reach (output even at
stop)
The terminal outputs an "active" signal when the running frequency
reaches the frequency lower limit (F0-14). The terminal also outputs the
"active" signal when the AC drive stops.
20
Frequency lower limit
reach (no output at stop)
If F8-15 (running mode when frequency reference lower than lower limit)
is set to 1 (stop), the terminal outputs an "inactive" signal no matter
whether the running frequency reaches the frequency lower limit.
If F8-15 (running mode when frequency reference lower than lower limit)
is set to 0 (run at frequency lower limit) or 2 (run at zero speed), the
terminal outputs an "active" signal when the running frequency reaches
the frequency lower limit.
21
Timing reach output
When the timing function (F8-46) is enabled, the terminal outputs an
"active" signal when the current operation time of the AC drive reaches
the set timing duration. The timing duration is defined by F8-47 and F8-
48.
