F3-04
Factory
default value
0 (No output)
RELAY refers to relay output terminal TA/TB/TC, in which TA is common
terminal of relay output, TB is the normally closed output terminal and TC is
the normally open terminal.
F3-01 to F3-04 function selections are as follows:
Setup
value
Function Description
0 No output The output terminals do not have any function.
1 Inverter running When the inverter is running, ON signal is output.
2 Fault output
When the inverter has fault, ON signal is output
Caution: It do not output ON signal upon
under-voltage.
3
Frequency level
detection FDT
arrival
Refer to F5-15 and F5-16 function codes for the
detailed descriptions.
4 Frequency arrival
Refer to F5-17 function code for the detailed
descriptions.
5
Frequency upper
limit arrival
When the operating frequency of the inverter reaches
the frequency upper limit, it outputs ON signal.
6
Frequency lower
limit arrival
When the operating frequency of the inverter reaches
the frequency lower limit, it outputs ON signal.
7
Running at zero
speed
When the inverter stops or is running, it outputs ON
signal.
8
Motor overload
pre-alarm
Judgment will be made according to the prealarm
parameter value before the motor electronic thermal
protection is enabled. If it exceeds the prealarm
parameter value, ON signal will be output. Refer to
FB-00 to FB-02 function codes for the descriptions of
motor overload.
9
Inverter overload
pre-alarm
When it is found that the inverter is overloaded, ON
signal will be output before the overload protection
occurs.
10
Setup counting
pulse value arrival
When the counting value reaches the frequency
upper limit, it outputs ON signal.
11 Designated When the actual length exceeds the setup value in
