Function
Description
7
Frequency upper limit
reached
If the running frequency reaches the upper limit, the terminal becomes ON.
8
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.
9
Frequency lower limit
reached (having output at
stop)
If the running frequency reaches the lower limit, the terminal becomes ON.
In the stop state, the signal is still ON.
10
Reverse running
If the frequency inverter is in the reverse running state, the terminal becomes
ON.
11
Zero-speed running (no
output at stop)
If the frequency inverter runs with the output frequency of 0Hz, the terminal
becomes ON. If the frequency inverter is in the stop state, the terminal
becomes OFF.
12
Zero-speed running 2
(having output at stop)
If the output frequency of the frequency inverter is 0Hz, the terminal
becomes ON. In the state of stop, the signal is still ON.
16
PLC cycle complete
When simple PLC completes one cycle, the terminal outputs a pulse signal
with width of 250ms.
17
Frequency-level detection
FDT1 output
Refer to the descriptions of b4-22 and b4-23.
18
Frequency level detection
FDT2 output
Refer to the descriptions of b4-25 and b4-26.
19
Frequency reached
Refer to the descriptions of b4-24.
20
Frequency 1 reached
Refer to the descriptions of b4-27 and b4-28.
21
Frequency 2 reached
Refer to the descriptions of b4-29 and b4-30.
22
Current 1 reached
Refer to the descriptions of b4-35 and b4-36.
23
Current 2 reached
Refer to the descriptions of b4-37 and b4-38.
24
IGBT Module temperature
reached
If the heatsink temperature of the inverter IGBT module (b9-07) reaches the
set module temperature threshold (b4-39), the terminal becomes ON.
25
Timing reached
If the timing function (b2-28) is valid, the terminal becomes ON after the
present running time of the frequency inverter reaches the set time.
26
Zero current state
Refer to the descriptions of b4-31 and b4-32.
27
Output current limit
exceeded
Refer to the descriptions of b4-33 and b4-34.
28
Under voltage state output
If the frequency inverter is in lower normal voltage state, the terminal
becomes ON.
29
Frequency inverter overload
pre-warning
The frequency inverter 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 bb-01 to bb-03.
30
Motor overheat warning
If the motor temperature reaches the temperature set inbb-27 (Motor
overheat warning threshold), the terminal becomes ON. You can view the
motor temperature by using U0-34.
31
Motor overload pre-warning
The frequency inverter judges motor overload according to preset motor
overload threshold, and terminal becomes ON. The overload threshold
setting refer to bb-01~bb-03.
32
Off load
If the motor load lost 0, the terminal becomes ON.
33
AI1 larger than AI2
When the input of AI1 is larger than the input of AI2, the terminal becomes
ON.
