Table 6-5 Functions of output terminals
Value Function Description
0 No output The terminal has no function.
1 AC drive running
When the AC drive is running and has output frequency
(can be zero), the terminal becomes ON.
2 Fault output (stop)
When the AC drive stops due to a fault, the terminal
becomes ON.
3
Frequency-level
detection FDT1 output
Refer to the descriptions of F8-19 and F8-20.
4 Frequency reached Refer to the descriptions of F8-21.
5
Zero-speed running
(no output at stop)
If the AC drive runs with the output frequency of 0, the
terminal becomes ON. If the AC drive is in the stop state,
the terminal becomes OFF.
6
Motor overload
pre-warning
The AC drive judges whether the motor load exceeds the
overload pre-warning threshold before performing the
protection action. If the pre-warning threshold is exceeded,
the terminal becomes ON. For motor overload parameters,
see the descriptions of F9-00 to F9-02.
7
AC drive overload pre-
warning
The terminal becomes ON 10s before the AC drive overload
protection action is performed.
8
Set count value
reached
The terminal becomes ON when the count value reaches
the value set in FB-08.
9
Designated count
value reached
The terminal becomes ON when the count value reaches
the value set in FB-09.
10 Length reached
The terminal becomes ON when the detected actual length
exceeds the value set in FB-05.
11 PLC cycle complete
When simple PLC completes one cycle, the terminal
outputs a pulse signal with width of 250 ms.
12
Accumulative running
time reached
If the accumulative running time of the AC drive exceeds
the time set in F8-17, the terminal becomes ON.
13 Frequency limited
If the set frequency exceeds the frequency upper limit or
lower limit and the output frequency of the AC drive reaches
the upper limit or lower limit, the terminal becomes ON.
14 Torque limited
In speed control mode, if the output torque reaches the
torque limit, the AC drive enters the stall protection state
and meanwhile the terminal becomes ON.
15 Ready for RUN
If the AC drive main circuit and control circuit become
stable, and the AC drive detects no fault and is ready for
RUN, the terminal becomes ON.
16 AI1 larger than AI2
When the input of AI1 is larger than the input of AI2, the
terminal becomes ON.
17
Frequency upper limit
reached
If the running frequency reaches the upper limit, the
terminal becomes ON.
18
Frequency lower limit
reached (no output at
stop)
If the running frequency reaches the lower limit, the terminal
becomes ON. In the stop state, the terminal becomes OFF.
