Description
8
Frequency reached
Refer to P08.36
9
Running in zero speed
Output ON signal when the inverter output frequency and
reference frequency are both zero.
10
Reach upper limit
frequency
Output ON signal when the running frequency reaches
upper limit frequency
11
Reach lower limit
frequency
Output ON signal when the running frequency reached
lower limit frequency
12
Ready to run
Main circuit and control circuit powers are established,
the protection functions do not act; when the inverter is
ready to run, output ON signal.
13
In pre-exciting
Output ON signal during pre-exciting of the inverter
14
Overload pre-alarm
Output ON signal after the pre-alarm time elapsed based
on the pre-alarm threshold; see P11.08–P11.10 for
details.
15
Underload pre-alarm
Output ON signal after the pre-alarm time elapsed based
on the pre-alarm threshold; see P11.11–P11.12 for
details.
23
Virtual terminal output of
Modbus communication
Output corresponding signal based on the set value of
Modbus; output ON signal when it is set to 1, output OFF
signal when it is set to 0
