Value
Function
Description
13
Set count value reached
The terminal becomes ON when the count value reaches the value set in
C3-08.
14
Designated count value
reached
The terminal becomes ON when the count value reaches the value set in
C3-09.
15
Length reached
The terminal becomes ON when the detected actual length exceeds the value
set in C3-05.
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 b4-24 and b4-25.
19
Frequency reached
Refer to the descriptions of b4-26.
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
Module temperature reached
If the heatsink temperature of the inverter 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 b4-24 and b4-25.
27
Output current limit
exceeded
Refer to the descriptions of b4-33 and b4-34.
28
Lower voltage state output If the frequency inverter is in lower 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 U0-33.
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 load becomes 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.
34
AI1 input limit exceeded
If AI1 input is larger than the value of b5-06 (AI1 input voltage upper limit)
or lower than the value of b5-05 (AI1 input voltage lower limit), the terminal
becomes ON.
35
Alarm output (all faults)
If a fault occurs on the frequency inverter and the frequency inverter
continues to run, the terminal outputs the alarm signal.
36
This time running time
reached
If the current running time of frequency inverter exceeds the value ofb2-31,
the terminal becomes ON.
