Function Description
29
Current 2 reach The DO outputs the active signal when the output current of
the AC drive is within the current detection range of F8‑40
(detection level of current 2).
Current detection range: F8‑40 – F8‑41 x F1‑03 (rated motor
current) to F8‑40 + F8‑41 x F1‑03
30
Timing reach
With the timing function (F8‑42) enabled, the DO outputs
the active signal when the current running time of the AC
drive reaches the set time. The timing duration is set
through F8‑43 and F8‑44.
31
AI1 input limit
exceeded
The DO outputs the active signal when the value of AI1 is
above F8‑46 (AI1 input voltage upper limit) or below F8‑45
(AI1 input voltage lower limit).
32
Load lost The DO outputs the active signal when the AC drive is in load
lost state.
33
Reverse running
The DO outputs the active signal when the AC drive is in
reverse running state.
34 Zero current
state
The DO outputs the active signal when the output current of
the AC drive remains in the zero current range for a period
longer than the value of F8‑35 (zero current detection delay).
Zero current detection range: 0 to F8‑34 x F1‑03
35 IGBT temperature
reach
The DO outputs the active signal when the IGBT module
temperature (F7‑07) reaches the temperature threshold (F8‑
47).
36 Output current
limit violation
The DO outputs the active signal when the output current of
the AC drive remains higher than the value of F8‑36 (output
overcurrent threshold) for a period longer than the value of
F8‑37 (output overcurrent detection delay).
37
Frequency lower
limit reach
(having output at
stop)
The DO outputs the active signal when the running frequency
reaches the lower limit (F0‑14). The DO also outputs the active
signal when the AC drive is stopped.
38
Alarm (all faults) The DO outputs the active signal when the AC drive is faulty,
and the fault protection action is "continue to run".
For details about fault protection actions, see the description
of parameters F9‑47 to F9‑50.
39 Motor
overtemperature
The DO outputs the active signal when the motor temperature
reaches the value of F9‑58 (motor overtemperature pre‑
warning threshold). You can check the motor temperature
using U0‑34.
40
Current running
time reach
The DO outputs the active signal when the current running
time of the AC drive exceeds the value of F8‑53 (current
running time threshold).
